Product Overview:

Function Introduction:

The WJ157 product realizes signal acquisition between sensors and hosts, used to decode encoder signals.
The
WJ157 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 WJ157 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 WJ157 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 WJ157 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 ℃.

The WJ157 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, 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 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.
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 the internal digital filter can also effectively suppress power
frequency interference from the power grid.
