Product Overview:

WAYJUN WJ62 series products realize the signal acquisition between sensor and host, to measure the switching signal. WJ62 series can be used in RS-232/485 bus industrial automation control system,switching signal measurement, monitoring and control, high and low leveal signal measurement,industrial field signal isolation and long-term industrial transmission 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 WJ62 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.
