Differential encoder pulse counter or speed measurement, Modbus RTU module  WJ157

Product features:

● Differential encoder converted to standard Modbus RTU protocol

Encoder 5V differential signal direct input

● It can be used as differential encoder counter or speed measurement

Differential 5V signal is directly input, encoder counts, and can recognize forward and reverse directions

It can also be set as a 2-way independent DI high-speed counter

Encoder count value supports automatic saving after power outage

The module can output 5V power to power the encoder

● Zeroing and setting count values can be achieved through the RS-485 interface

Wide power supply range: 8~32VDC

High reliability, easy programming, and easy application

Standard DIN35 rail installation for convenient centralized wiring

● User can programmatically set module address, Baud, etc

Product Overview:

The WJ157 product achieves signal acquisition between sensors and the host, used to decode encoder signals. The WJ157 series of products can be applied in RS-485 bus industrial automation control systems, automated machine tools, industrial robots, three coordinate positioning systems, displacement measurement, stroke measurement, angle measurement, speed measurement, flow measurement, product counting, and so on.

The products include signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect 255 WJ157 series modules at most. The communication mode adopts ASCII code communication protocol or MODBUS RTU communication protocol. The Baud can be set by code and can be hung on the same RS-485 bus with the control module of other manufacturers, which is convenient for computer programming
