 Function Description:
WJ*8 signal isolation acquisition module can be used to measure eight channels voltage or current signal,
1. Analog signal input
**-Bit acquisition accuracy, eight channels analog input. All products signal input range have been calibrated. In use,
users also can program calibration easily.
About the specific current or voltage input range, please see product selection.
2. Communication protocol
Communication Interface: one channel standard RS***5 communication interface, or one standard RS***2
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: *0 Bits. 1 start bit,8 data bits,1 stop bit.
Address: (0 to **5) and baud rate (***0,***0,***0,***0,****0,****0 bps) can be set, the most long-distance
about communication networks is up to ***0 meters, through the twisted-pair shielded cable.
Communication interface of high anti-jamming design, ± *5KV ESD protection, communication response time is less
than **0mS.
