RS485 Double-Meter controller

Connected with computer controlled card of rectifier,adopt RS485 network communication system ,which utilizes two-core twisted pair shielded wire to perform communication, all digital network transmission is high in control accuracy, of zero-decrement, strong in interference rejection, far in communication distance.

The controller has two groups of communication ports, A1, B1 and A2, B2. A1, B1 are near communication ports and connected to the rectifier, while A2, B2 are remote communication ports and connected to the upper machine. RS485 double-chart controller is mainly used for site control of automatic line or RS485 control of a single rectifier.

The controller has the following functions:

(1)Display and set function of voltage and electric current.

(2)Option functions of on/off, voltage stabilization /current stabilization.

(3)Option function of long-distance and local control.

(4)Initialization function of lower computer.

(5)Fault inquiry function and more.

(1)Ambient temperature: -10℃ to 45℃

(2)Height above sea level: ≤1500 m

(3)Relative humidity: ≤85%

(4)Free from conductive dust, explosive articles, corrosive gas

(5)Free from strong vibration

(6)Indoors installment
