Product Overview:
The WJ150 product realizes the signal acquisition between the sensor and the host, and is used to
decode the encoder signal. WJ150 series products can be used in RS-485 bus industrial automation control
systems, automated machine tools, industrial robots, three-coordinate positioning systems, displacement
measurement, stroke measurement, angle measurement, rotational speed measurement, flow measurement,
product counting, etc.
Function introduction:
WJ150 remote I/O module can be used to measure 1-channel encoder signal, and can also be set as
2-channel independent counter or DI state measurement.
1. Signal input
1-channel encoder signal input or 2-channel independent counter, which can be connected to dry contact
and wet contact, and the input type can be set by command.
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,
and can realize network communication with PLC, RTU or computer monitoring systems of various brands.
Data format: 10 bits. 1 start bit, 8 data bits, 1 stop bit. No verification.
The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600,
115200bps) can be set; the longest distance of the communication network can be up to 1200 meters, which is
connected by twisted pair shielded cable.
The communication interface is designed with high anti-interference, ±15KV ESD protection, and the
communication response time is less than 100mS.
3. Anti-interference
Checksums can be set as required. There are transient suppression diodes inside the module, which can
effectively suppress various surge pulses, protect the module, and internal digital filtering, and can also well
suppress power frequency interference from the power grid.
