Allen-Bradley 1794-IB16 16 Point Digital Input Module

Operating Voltage: Adopts 24V DC power supply. This voltage specification conforms to the common standards of digital sensors and switchgear in the industrial field, facilitating matching with on-site equipment and ensuring the stable operation of the module.

Input Voltage Range: Supports an input voltage of 10-30V DC, with a certain voltage adaptability. It can be compatible with industrial power supplies and sensor output signals of different specifications, improving the versatility of the module.

Input Current: The typical operating current of each input channel is about 7mA (under 24V DC condition). The overall power consumption is low, which can effectively reduce the energy consumption of the system.

Number of Input Points: It has 16 independent digital input channels, which can collect 16 digital signals at the same time. It meets the demand for multi-signal parallel acquisition in medium and large industrial control scenarios, reduces the number of modules used, and optimizes the system layout.

Input Type: Supports DC digital input and adopts photoelectric isolation, which can effectively isolate on-site signals from the internal circuit of the module, improving the anti-interference ability and safety of the module.

Response Time: The input signal has a fast response speed, usually with a turn-on response time ≤1ms and a turn-off response time ≤1ms. It can quickly capture changes in on-site signals, ensuring that the control system can obtain equipment status in a timely manner and meet the needs of high real-time control scenarios.

Isolation Performance: Electrical isolation design is adopted between channels, with an isolation voltage usually of 250V AC. It can effectively prevent signal interference between different channels, especially suitable for complex industrial environments where multiple signals are collected at the same time.

Operating Temperature: It can work stably in the temperature range of -25℃ to 70℃, adapting to temperature changes in different environments such as industrial production workshops and outdoor equipment rooms. Even in low-temperature cold storage warehouses or high-temperature metallurgical workshops, it can maintain reliable signal acquisition performance.

Relative Humidity: It can operate normally in a relative humidity environment of 5%-95% (non-condensing), and can cope with scenarios such as humid food processing workshops and sewage treatment plants, effectively preventing circuit faults caused by humidity.

Anti-electromagnetic Interference: It complies with industrial electromagnetic compatibility standards (such as IEC 61000-6-2), has strong anti-electromagnetic interference ability, and can resist electromagnetic interference generated by industrial on-site motors, frequency converters, electric welders and other equipment, ensuring the accuracy of input signal acquisition.

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 can reach 30g (11ms). It can withstand vibration and shock generated during the operation of industrial equipment, ensuring the stability of the module structure and performance.

Multi-channel Signal Parallel Acquisition: The 16 input channels are independent of each other and can collect 16 digital signals at the same time, and the acquisition process of each channel does not interfere with each other. For example, in an automated production line, it can collect signals such as workpiece arrival signals and equipment operation status signals from multiple stations at the same time, providing comprehensive on-site information for the control system and realizing overall monitoring of the production process.

High-speed Signal Response: It has a fast signal response capability and can capture changes in input signals within 1ms. For scenarios requiring precise control (such as sensor signal acquisition of high-speed sorting equipment), it can ensure that the control system responds in a timely manner, avoiding production errors caused by signal delay.

Photoelectric Isolation Protection: It adopts photoelectric isolation technology to electrically isolate the on-site input signal from the internal circuit of the module, preventing on-site high-voltage, surge and other interference signals from entering the control system, protecting the module and controller from damage, and improving the stability and reliability of signal acquisition.

Status Indication Function: The module is equipped with 16 LED indicators, corresponding to the input channels one by one, which can display the signal status of each channel in real time (lights up when there is a signal input, and turns off when there is no signal). By observing the status of the indicators, operators can intuitively judge the signal acquisition situation of each channel, facilitating quick troubleshooting of sensor faults, wiring problems, etc., and improving the maintenance efficiency of the system.

Seamless Integration with the System: As part of the Flex I/O series, 1794-IB16 can work seamlessly with Flex I/O racks, communication modules (such as 1794-ACN) and Logix series controllers. It transmits the collected signals to the controller through the rack backplane or communication network, with low data transmission delay and fast response. It supports configuration and parameter setting through RSLogix 5000 or Studio 5000 programming software, perfectly integrating with the control system, and the operation is convenient.

Automobile Welding Production Line: In automobile welding production lines, there are a large number of welding robots, fixtures, conveying equipment, etc., and it is necessary to collect the operating status signals of each equipment in real time (such as robot arrival signals, fixture clamping signals, workpiece conveying arrival signals, etc.). The 1794-IB16 module can collect these signals at the same time through 16 input channels and transmit them to the control system. The controller coordinates the actions of each equipment according to the signal status, ensuring the orderly progress of the welding process and improving welding quality and production efficiency.

Automated Stereoscopic Warehouse: In automated stereoscopic warehouses, the running position of stackers, the presence or absence of goods in Storage location，and the start-stop status of conveyor lines need to be detected by sensors. The 1794-IB16 module can collect digital signals from these sensors (such as photoelectric sensors to detect whether there are goods in the Storage location，limit switches to detect whether the stacker is in place, etc.) and transmit the signals to the warehouse management system. The system judges the running path and actions of the stacker according to the signals, realizes automatic access and transportation of goods, and improves the automation level of warehousing and logistics.

Packaging Machinery Control System: In food, pharmaceutical and other packaging machinery, it is necessary to detect the arrival of packaging materials, the filling status of products, the completion signal of sealing, etc. The 1794-IB16 module can collect these digital signals and transmit them to the controller. The controller controls the feeding, filling, sealing and other actions of the packaging machinery according to the signal status, ensuring the continuity and stability of the packaging process, avoiding problems such as missing packages and wrong packages, and ensuring the quality of product packaging.
