Factory Capabilities

 Product Overview:
 WJ158
 The WJ158 product realizes signal acquisition between sensors and hosts, used to decode encoder signals. The
 WJ158 series 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 more.
 The product includes signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication.
 Each serial port can connect up to 255 WJ158 series modules, and the communication method adopts ASCII code
 communication protocol or MODBUS RTU communication protocol. The baud rate can be set by code and can be hung
 on the same RS-485 bus as control modules from other manufacturers, making it easy for computer programming.The WJ158 series products are intelligent monitoring and control systems based on microcontrollers. All user set
 configuration information such as address, baud rate, data format, parity status, etc. are stored in non-volatile memory
 EEPROM.
 The WJ158 series products are designed and manufactured according to industrial standards, with no isolation
 between signal inputs/outputs, strong anti-interference ability, and high reliability. The working temperature range is-45 ℃to+85 ℃.

 Function Introduction:
 The WJ158 remote I/O module can be used to measure 1 differential encoder signal or set as 2 independent differential
 counters.
 1,Signal input
 One 5V differential encoder signal input or two independent 5V differential counters.
 2,signal output
 One DOsignal output, with a high level approximately equal to the power supply voltage and a low level of 0V, can
 directly drive the intermediate relay and set the output mode through commands.
 3,Communication Protocol
 Communication interface: 1 standard RS-485 communication interface.
 Communication Protocol: Supports two protocols, the character protocol defined by the command set and the
 MODBUSRTUcommunication protocol. The module automatically recognizes communication
 protocols and can achieve network communication with various brands of PLCs, RTUs, or computer
 monitoring systems.
 Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. No verification.
 The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set;
 The communication network can reach a maximum distance of 1200 meters and is connected through
 twisted pair shielded cables.
 High anti-interference design of communication interface, ± 15KV ESD protection, communication response time
 less than 100mS.
 4,anti-interference
 Parity check can be set as needed. There is a transient suppression diode inside the module, which can effectively
 suppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power
 frequency interference from the power grid.
