Description
Description:The 4DI4DO4AI controller can support the input of 4 digital inputs, 4 analog inputs, and 4 relay outputs. It supports Modbus RTU protocol and can be directly adapted to PLC, DCS and various domestic configuration software. The product has a high degree of ease of use, users can easily and quickly integrate into their own systems.
The signal input and output are isolated from the RS485 communication electrical signal, effectively suppressing various serial mode and common mode interference, ensuring the accuracy of the data, and also ensuring the reliable operation of the module.
Features:
1. Adopt standard Modbus-RTU protocol.2. Safety: signal input and output are isolated from RS485 communication electrical signals3. Communication protection: RS485 communication signal output interface adopts overvoltage and overcurrent double protection.4. The input and output signal type and communication format can be set by the host computer software.5. The power polarity is protected against reverse connection.
