The configuration information such as status is stored in the non-volatile memory EEPROM.
The WJ65 series products are designed and manufactured according to industrial standards, with 3000V triple isolation between signal input, output, and communication interfaces, strong anti-interference ability, and can
High reliability. Working temperature range -45 ℃ to+85 ℃.
Function Introduction:
The WJ65 remote I/O module can be used to measure eight switch signals and has eight switch outputs.
1. Switching signal input and output
8-way switch signal input, can be connected to dry and wet contacts, please refer to the wiring diagram for details; 8-way switch signal output with open collector output,
You can issue commands to set internal pull-up output.
2. Communication protocol
Communication interface: 1 standard RS-485 communication interface or 1 standard RS-232 communication interface, specified when ordering and selecting.
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 multiple brands of PLC, RTU or computer monitoring systems.
Data format: 10 digits. 1 start bit, 8 data bits, 1 stop bit, no checksum.
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 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 can be set as needed. There is a transient suppression diode inside the module, which can effectively suppress various surge pulses and protect the module.
