1.WJ27-485 (8-channel thermocouple signal input, output is RS-485 interface)
2.WJ27-232 (8-channel thermocouple signal input, output is RS-232 interface)
WJ27 signal isolation acquisition modulecan be used to measure eight channels thermocouple signal
Â 1. Temperature signal input
Â 24-Bitacquisition accuracy, 8-CH thermocouple signal input. All products signal inputrange have been calibrated. In use, users also can program calibration easily.
Â 2. Communication protocol
Â Â CommunicationInterface: one channel standard RS-485 communication interface, or onestandard RS-232 communication interface, specify when ordering.
Â Â CommunicationProtocols: supports two protocols, characters protocol of the command setdefined and MODBUS RTU communication protocol. Can be programmed using the kindof communication protocol, can be achieved with PLC, RTU of many Brands orcomputer monitoring system for network communication.
