The WJ68 remote I/O module can be used to measure eight PNP switch signals and has eight PNP switch outputs. 1, Switching signal input and output
8-channel switch signal input, capable of connecting dry and wet contacts. Please refer to the wiring diagramfordetails; 8-way switch PNP signal output, with an output voltage equal to the power supply voltage andamaximum output current of 100mA. Be careful not to overload the output, otherwise it will burn out the output
channel. 2, Communication Protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communicationinterface, please specify when ordering and selecting. Communication Protocol: Supports two protocols, the character protocol defined by the command set andtheMODBUS RTU communication protocol. The module automatically recognizes communicationprotocols and can achieve network communication with various brands of PLCs, RTUs, or computermonitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) canbeset;The communication network can reach a maximum distance of 1200 meters and is connectedthroughtwisted pair shielded cables. High anti-interference design of communication interface, ± 15KV ESD protection, communication responsetimeless than 100mS. 3, anti-interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which caneffectivelysuppress various surge pulses and protect the module
