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.
