 The WJ66 remote I/O module can be used to measure four encoder signals and has eight switch outputs. It can be used
 as a 4-channel encoder counter or 4-channel speed measurement, and can also output 8-channel PWM signals.
 1,Signal input and output
 4-channel encoder signal input, can be connected to dry and wet contacts, please refer to the wiring diagram for
 details; 8-channel switch signal output with open collector output.
 2,Communication Protocol
 Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication
 interface, please specify when ordering and selecting.
 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.
 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
 Checksums 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.
