WJ61 Switch signal isolation acquisition module can be used to measure 16 channels switching signal.
1. Switch signal input
16 channels switching signal. input/output is isolated. Support 16-ch dry contact input or 16-ch wet contact input
2. Communication protocol
Communication Interface: one channel standard RS-485 communication interface, or one standard RS-232
communication interface, specify when ordering.
Communication Protocols: supports two protocols, characters protocol of the command set defined and MODBUS
RTU communication protocol. Can be programmed using the kind of communication protocol, can be
achieved with PLC, RTU of many Brands or computer monitoring system for network communication.
Data Format: 10 Bits. 1 start bit,8 data bits,1 stop bit.
Address: (0 to 255) and baud rate (2400,4800,9600,19200,38400 bps) can be set, the most long-distance about
communication networks is up to 1200 meters, through the twisted-pair shielded cable.
Communication interface of high anti-jamming design, ± 15KV ESD protection, communication response time is less
