RS485 Modbus Communication and Automatic Control Equipment for Air Conditioning
RS485 Modbus RTU - Automatic Control Equipment for Air Conditioning
It is an automatic control device for air conditioning, such as sensors with communication functions, damper actuators, and valves, which can reduce the labor required for wiring work.
This product has general-purpose RS485 Modbus RTU communication functionality. It can connect sensors, damper actuators, valves, etc., to the controller using a two-core twisted pair cable. 【Features】 - Each product has wiring for power and communication lines, which simplifies wiring work. - For example, the wiring for sensors and damper actuators inside air conditioning units becomes simpler. - Simplifying the wiring reduces the possibility of connection errors during installation. - No additional input/output expansion units are needed on the controller side (it can be completed with just one terminal for communication). - Wireless communication for the communication line is also possible, further simplifying wiring work.
