The Series 4V 1/4 DIN Temperature Controller displays and controls the current position of a valve or damper by accepting in a signal from a position indicator such as our QV series. The controls can be programmed for ON/OFF, PID, ramp and soak, auto-tuning, or manual tuning control methods. For greater design flexibility, the Series 4V accepts thermocouple, RTD, current or voltage inputs. An auto/manual key is located on the front panel in order to toggle between manual operation and automatic operation. The RS-485 serial communications can work with either ASCII or Modbus® RTU protocol. During normal operation, the controller will display the present value (PV), set point value (SV) and the current valve position (%). The Series 4V is equipped with two programmable alarm set points. | |
