8-way DI high-speed counter, 8 channels support PWM output, Modbus RTU module WJ63

product description:

WJ63 product implements signal acquisition between sensors and hosts, used to pulse signal counting and device control. WJ63 series products can be applied to the RS-232/485 bus industrial automation control system, photoelectric switch signal count measurement, PWM signal output and frequency measurement, and the like.

Products include signal isolation, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can be connected to 255 WJ63 series modules. The communication mode uses the ASCII code communication protocol or the Modbus RTU communication protocol. The baud rate can be set by code settings, can be hung on the same RS-485 bus with other manufacturers' control modules, easy to computer Program.

The WJ63 series is based on a single-chip intelligent monitoring and control system, all user settings, baud rates, data formats, checksum, and other configuration information stored in non-volatile memory EEPROM.

WJ63 series products are isolated from industrial standards, manufacturing, signal input / output, can withstand 3000VDC isolation voltages, strong anti-interference ability, high reliability. Working temperature range - 45 ° C ~ + 85 ° C.
