Function Description:
WJ29 signal isolation acquisition module can be used to measure 16 channels voltage or current signal,
1. Analog signal input
 24-Bit acquisition accuracy, 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-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
than 100mS.
 3. Anti-jamming
 According to need to set the checksum. Module internal has transient suppression diodes, can inhibit a variety of surge
pulse, protection module, and internal digital filter can also be well suppressed from the grid frequency interference.
