The WJ69 remote I/O module can be used to measure eight-channel encoder signals, and it can also be set as a16-channel independent counter or DI state measurement.
1. Signal input
8-channel encoder signal input or 16-channel independent counter can be connected to dry contact and wet contact.Please refer to the wiring diagram section for details.
2. Communication protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface,specify when ordering and selecting.
Communication protocol: supports two protocols, the character protocol defined by the command set and theMODBUS RTU communication protocol. The module automatically recognizes the communication protocol and canrealize network communication with various brands of PLC, RTU or computer monitoring systems.
Data format: 10 bits. 1 start bit, 8 data bits, 1 stop bit. No verification.
The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; thelongest distance of the communication network can reach 1200 meters, and it is connected through a twisted pairshielded cable.
The communication interface is designed with high anti-interference, ±15KV ESD protection, and the communicationresponse time is less than 100mS.
3. Anti-interference
The checksum can be set as required. There are transient suppression diodes inside the module, which can effectivelysuppress various surge pulses, protect the module, and the internal digital filter can also suppress the power frequencyinterference from the power grid.
