Product Overview:

The WJ152 product implements signal acquisition between sensors and hosts for measuring PWM signals. WJ152 series products can be applied to RS-485 bus

Industrial automation control systems, automated machine tools, industrial robots, three coordinate positioning systems, PWM measurement, servo measurement, 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 WJ152 series modules,

The communication method adopts ASCII code communication protocol or MODBUSRTU communication protocol, and the baud rate can be set by code, which can be hung with control modules from other manufacturers

On the same RS-485 bus, it is convenient for computer programming.

The WJ152 series products are intelligent monitoring and control systems based on microcontrollers, with all user set addresses, baud rates, data formats, and parity checks

The configuration information such as verification status is stored in non-volatile memory EEPROM.

The WJ152 series products are designed and manufactured according to industrial standards, with no isolation between signal inputs/outputs, strong anti-interference ability, and high reliability. Working temperature
The temperature range is -45 ℃ to+85 ℃.
Function Introduction:
The WJ152 remote I/O module can be used to measure 2 PWM signals.
1. Signal input
2-channel PWM signal input, can be connected to dry contacts and wet contacts, and the input type can be set through commands.
2. 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 MODBUS RTU communication protocol. The module automatically recognizes the communication protocol,
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; communication
The longest distance of the network can reach 1200 meters, connected through twisted pair shielded cables.
High anti-interference design of communication interface, ± 15KV ESD protection, communication response time less than 100mS.
3. 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
Digital filtering can also effectively suppress power frequency interference from the power grid.
