I. Product Overview

Rockwell Automation 1769-OW8I is a digital output module in the CompactLogix series, mainly used to convert digital control commands from the controller into executable switch signals in industrial fields, driving various AC load devices to act. As a key interface between the control system and AC actuators, it can receive commands from the CompactLogix controller and send switch signals to AC contactors, solenoid valves, indicator lights and other equipment through output channels, realizing control over the start/stop and state switching of AC equipment in industrial production. The module adopts a modular design, highly compatible with 1769 series racks and controllers, with easy installation and flexible wiring. It is widely used in fields involving AC equipment control such as machine tool manufacturing, textile machinery, heating, ventilation and air conditioning (HVAC), and warehousing logistics, providing reliable output support for the stable operation of industrial automation systems.

II. Performance Parameters

Power Parameters: It adopts a backplane power supply mode, obtaining working power (usually 5V DC) from the CompactLogix rack, without the need for additional independent working power supplies, which simplifies system wiring. The output circuit requires an external AC power supply, supporting 120V AC or 240V AC (depending on the specific model), to provide driving power for connected AC actuators. The external power frequency is usually 50/60Hz, adapting to power grid standards in different regions.

Output Parameters:
Number of Output Points: It has 8 digital output channels, which can control 8 AC actuators at the same time, meeting the needs of multi-equipment control in small and medium-sized industrial control scenarios, reducing the number of modules used and optimizing system layout.
Output Type: It supports AC digital output, using relay output mode, which has strong load driving capacity and electrical isolation performance. It is suitable for controlling various AC load devices and has strong compatibility with load types (such as resistive and inductive loads).
Output Current: The maximum continuous output current of each channel is usually 2A (for resistive loads). For inductive loads, the maximum output current will be reduced accordingly (such as 1A). It can directly drive small AC contactors, solenoid valves and other equipment. If it is necessary to control higher-power equipment, it needs to be used with an intermediate relay.
Mechanical and Electrical Life: The mechanical life of relay contacts can reach millions of times, and the electrical life is usually tens of thousands of times under rated load, ensuring that the module has a long service life and reducing the frequency of maintenance and replacement.
Response Time: The turn-on response time of the output signal is generally within 10ms, and the turn-off response time is within 5ms, which can quickly execute the commands issued by the controller, meeting the requirements of conventional industrial control for response speed.

Isolation Performance: Electrical isolation design is adopted between channels, with an isolation voltage usually of 250V AC, which can effectively prevent signal interference between different channels, improve the anti-interference ability of the system, and is especially suitable for scenarios where multiple load devices work at the same time.

Environmental Parameters:
Operating Temperature: It can work stably in the temperature range of 0℃-60℃, adapting to temperature changes in conventional environments such as industrial production workshops and control cabinets, with no obvious impact on performance.
Relative Humidity: It can operate normally in a relative humidity environment of 5%-95% (non-condensing), coping with humid industrial places and effectively preventing circuit faults caused by humidity.
Anti-Electromagnetic Interference: It complies with industrial electromagnetic compatibility standards, has a certain anti-electromagnetic interference ability, and can resist electromagnetic interference generated by motors, frequency converters and other equipment in industrial sites, ensuring the stability of output signals.
Vibration and Shock Resistance: The vibration resistance range is 10-500Hz, with an amplitude of 0.38mm or an acceleration of 10g; the shock resistance range is generally 15g (11ms). It can withstand vibration and shock generated during the operation of industrial equipment, ensuring the stability of the module's structure and performance.

III. Functional Features

Independent Channel Control: The 8 output channels are independent of each other, and can respectively receive commands from the controller for switching actions without affecting each other. They can realize individual control or linkage control of different AC actuators, meeting diversified control needs. For example, in a production line, it can separately control the start/stop of AC motors in different processes to realize the collaborative work of various links.

Status Indication Function: The module is equipped with 8 LED indicators, corresponding to the output channels one by one, which can display the output status of each channel in real time (lights up when turned on, turns off when turned off). By observing the status of the indicators, operators can intuitively judge the working condition of each channel, facilitating quick troubleshooting of actuators or wiring faults and improving maintenance efficiency.

Overload and Short-Circuit Protection: Some models have overload and short-circuit protection functions. When an overload or short-circuit occurs in the output channel, the module will limit the output current through internal protection mechanisms to avoid damage to the module. At the same time, relay contacts have a certain anti-welding ability and are not easy to stick in case of short-term short circuits, ensuring system safety.

Compact Structure Design: It adopts the standardized size of 1769 series modules, with a compact structure and small volume, which can be directly installed on 1769 series racks, saving installation space. The wiring terminals adopt a plug-in design, making wiring convenient and fast, facilitating on-site installation and later maintenance, and improving work efficiency.
Seamless Integration with the System: As part of the CompactLogix series, 1769-OW8I can work seamlessly with the series' controllers and other I/O modules, transmitting data with the controller through the rack backplane, with fast response and low command execution delay. It can be configured and programmed through RSLogix 5000 or Studio 5000 programming software, perfectly integrating with the control system, and the operation is convenient.

IV. Application Scenarios

Machine Tool Equipment Control: In machine tools such as lathes, milling machines, and grinders, 1769-OW8I can receive commands from the controller and control the start/stop of AC equipment such as cooling pump motors, lubricating pump motors, and lighting systems of the machine tools through output channels. For example, when the controller detects a machine tool start signal, the module outputs a signal to turn on the cooling pump and lubricating pump, providing cooling and lubrication for the machine tool processing process and ensuring the normal operation of the equipment.

HVAC Systems: In HVAC systems of industrial plants or commercial buildings, the module can control the operation of AC equipment such as fans, compressors, and heaters of air conditioning units. According to the ambient temperature collected by temperature sensors, the controller adjusts the start/stop of corresponding equipment through module output signals, realizing automatic control of indoor temperature and maintaining a comfortable ambient temperature.

Warehousing and Logistics Equipment: In stackers and conveyor line systems of automated warehouses, 1769-OW8I can control the actions of AC motor contactors, braking devices and other equipment. For example, according to the position information of goods, the controller controls the start/stop and forward/reverse rotation of AC motors of the conveyor line through module output signals, realizing accurate transportation and transfer of goods and improving the automation level of warehousing and logistics.
Textile Machinery Control: In textile machinery such as textile machines and printing and dyeing machines, the module can control the operation of AC equipment such as traction motors, winding motors, and heating devices of the equipment. According to the requirements of production processes, the controller adjusts the working status of each equipment through module output signals, ensuring the quality and production efficiency of textile products.
