Product Overview:
 WAYJUN WJ27 series products realize the signal acquisition between sensor and host, to measure eight channels
thermocouple signal. WJ27 series products can be applied to RS-232/485 bus industrial automation control system, J/ K/
T/ E/ R/ S/ B type thermocouple signal measurement, monitoring and control and so on.
Products include power supply isolation, signal isolation, linearization, A/D conversion and RS-485 serial
communication. Each serial interface can connect up to 255 pieces WJ27 Series modules, communication using ASCII
code or MODBUS RTU communication protocol, and its instruction set compatible with the ADAM modules, baud rate
can been set by the code, with other manufacturers control module hang in the same RS-485 bus for easy programming.

WJ27 series products are based on SCM's intelligent monitoring and control system, users set the calibration value,
address, baud rate, data format, checksum status, and configuration information are all stored in nonvolatile memory
EEPROM.
 WJ27 products are according to industry standard design, isolation between signal input / output, can withstand
voltage 3000VDC, high anti-interference ability and reliability. Operating temperature range is - 45 ~ +85 °C.
