1 channel encoder speed measurement or 2 DI frequency measurement, 1 channel DO speed alarm output

product description:

WJ151 product implements signal acquisition between sensors and hosts to decode encoder signals. WJ151 series products can be applied to RS-485 bus industrial automation control systems, automated machine tools, industrial robots, three-situ positioning systems, displacement measurements, stroke measurements, angular measurements, speed measurements, flow measurement, product counting, etc.

Products include signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can be connected up to 255 WJ151 series modules, the communication mode uses the ASCII code communication protocol or the Modbus RTU communication protocol, the baud rate can be set up by the code, can be hung on the same RS-485 bus with other manufacturers' control modules, easy to computers Program.

The WJ151 series is based on the intelligent monitoring and control system of single chip microcomputer. All user-set addresses, baud rates, data formats, checksum and other configuration information stored in non-volatile memory EEPROM.

WJ151 series products are designed, manufactured, and signal input / output is not isolated from industrial standards, strong anti-interference ability and high reliability. Working temperature range - 45 ° C ~ + 85 ° C.


● Encoder count Conversion to standard Modbus RTU protocol

● Coding speed measurement, can identify positive reversal, can alarm output

● You can also set as a 2nd independent DI high speed counter

● All the way the DO output can be set to count or frequency alarm signals

● Count value supports power-on automatic save

● DI input supports PNP and NPN input

● Filter time can be set when the relay and mechanical switch input

● Clear and set the count value via the RS-485 interface.

● Wide power supply range: 8 ~ 32VDC

● High reliability, convenient programming, easy to apply

● Standard DIN35 rail installation, convenient centralized wiring

● User programmable setting module address, baud rate, etc.

typical application:

● Encoder pulse signal measurement and alarm

● Flowmeter pulse count or flow measurement

● Production line product count

● Quantity count of logistics package

● Close to switch pulse signal measurement

● Encoder signal is remote to the industrial computer

● Water meter or electric meter pulse count

● Intelligent factory and industrial network
