Function Introduction:
The Deming Electronics 93 remote I/O module can be used to measure eight channels of digital signals and has eight channels of digital outputs. It can function as an 8-channel counter or 8-channel frequency measurement device,
and can also output 8 channels of PWM signals.
1、 Digital Signal Input and Output
8 channels of digital signal input, compatible with dry contacts and wet contacts (please refer to the wiring diagram section for details); 8 channels of digital signal output with open-collector output.
2、 Communication Protocol
Communication interface: RJ-45 Ethernet interface. The two indicator lights near the Ethernet port: the Link light (green) stays on when the network cable is connected, and the Data light (yellow) flashes intermittently.
Communication protocol: MODBUS TCP protocol is used for industrial Ethernet data exchange. The control module can also be accessed directly via a web page.
Network buffer: 2K Byte (both for receiving and sending)
Communication response time: less than 10mS.
3、 Anti-interference
The module has built-in transient suppression diodes, which can effectively suppress various surge pulses and protect the module.
