PLC Intelligent Display Controller With 485 Communication Input Signal

Temperature Controller With 485 Communication PLC Computer Temperature Controller Temperature Instrument

The D series intelligent display controller is a new type of instrument independently researched and developed by introducing advanced foreign technology and aiming at the particularity of the hydropower industry. The accuracy, anti-interference, intelligence, stability, and reliability of the instrument have reached the international advanced level, and it can completely replace the imported display controller.

Main functions:

Modbus RTU 485 communication input signal (sensor type):
