The module has strong power adaptability, and can maintain a stable working state within the voltage fluctuation range of 24V DC±10%, ensuring the accuracy of signal acquisition and output.
Input signal parameters: It supports two digital input methods: dry contacts and wet contacts. Dry contact input does not require external power supply and is suitable for connecting mechanical contact devices such as travel switches and limit switches; wet contact input requires an external 24V DC power supply and can be directly connected to active devices such as photoelectric sensors and magnetic switches. The effective voltage range of the input signal is 18 - 30V DC, which can accurately identify effective signals and avoid false triggering.
Output signal parameters: It adopts transistor output form, and each output channel has a rated load of 30V DC/2A, which can directly drive small solenoid valves, indicator lights, small relays and other equipment. Transistor output has fast response speed and long service life, making it suitable for control scenarios with frequent switching.
Power consumption: The power consumption during normal operation is low, usually not exceeding 6W, which will not bring excessive burden to the system power supply. At the same time, it reduces the heat generation of the module, which is beneficial to prolonging its service life.
(2) Performance Parameters
Channel configuration: It has 16 digital input channels and 8 digital output channels. This combination of channel quantities is suitable for industrial scenarios that need to monitor more status signals and control a certain number of executive equipment. It can meet the needs of small and medium-sized control loops, improve the integration of the system, and reduce equipment costs.
Response time: The response time of the digital input channel is less than 1ms, which can quickly capture the status changes of on-site equipment; the response time of the digital output channel is less than 2ms, which can timely transmit control instructions to executive equipment, ensuring the real-time performance of control and performing excellently in occasions with high requirements for response speed.
Isolation performance: Photoelectric isolation technology is adopted between input channels, between output channels, and between input and output channels. The isolation voltage reaches 2500V AC, which can effectively prevent on-site strong electrical interference and ground potential difference from affecting the module and the control system, improving the anti-interference ability and stability of the system.
Output channel life: The electrical life of transistor output can reach more than 1 million times, which can meet the needs of long-term frequent operations, reduce the replacement frequency of modules, and lower maintenance costs.

III. Functional Features
(1) Hybrid Control, Efficient Integration
Integration of input and output: The functions of digital input and output are integrated into one module, reducing the number of modules in the system, simplifying system wiring and control cabinet layout, and reducing the complexity and cost of the system. At the same time, the close-distance design of input and output channels shortens the signal transmission path and improves the control response speed.
In-depth collaboration with DeltaV system: As a dedicated module for the DeltaV system, it can achieve seamless connection with the system's controllers, configuration software, etc. During system configuration, module parameter configuration and channel mapping can be quickly completed through DeltaV software; during operation, data exchange between the module and the controller is efficient and smooth, ensuring timely upload of on-site status information and rapid issuance of control instructions.
(2) Reliable Signal Processing and Control
Accurate signal acquisition: The digital input channel adopts a high-sensitivity photoelectric coupler and filter circuit, which can accurately identify on-site digital signals, effectively suppress spike pulses and electromagnetic interference, and avoid misjudgment. For example, when monitoring the product in-place signal of the production line, even if there is interference from motor operation on site, the module can accurately capture the real signal.
Stable output control: The transistor of the digital output channel has good switching characteristics and stability, and can reliably control the on-off of the load. The module also has an overcurrent protection function. When the output current exceeds the rated value, it will quickly cut off the output to protect the transistor and the module from damage, and the output can be automatically restored after the fault is eliminated.
(3) Comprehensive Diagnosis and Protection
Channel status diagnosis: Each input and output channel has an independent status diagnosis function, which can monitor the signal status and working conditions of the channel in real time. When the input channel is disconnected or short-circuited, or the output channel transistor fails, the module will timely upload the fault information to the DeltaV control system and send an alarm signal through the system, facilitating operators to quickly locate and eliminate the fault.
Module self-diagnosis: The module has a perfect self-diagnosis function, which can monitor its own power supply status and internal circuit working status in real time. When the module has problems such as abnormal power supply and internal chip failure, it will immediately trigger an alarm to remind maintenance personnel to handle it in time, improving the maintainability and reliability of the system.
