The R2-50 programmable multifunction controller is a high performance device which can adapt to a wide variety of industrial applications. It can operate as a single or double loop controller, and allows a range of control strategies to be applied: heat/cool control, remote set-point, cascade, feedforward, override; it can also be used as a motorised valve controller with potentiometer feedback; other control strategies can be provided on request. It also allows set point programming for complex thermic profiles and operating timetable for automatic start/stop. It provides two universal control inputs (TC, Pt100, V, mA) and two programmable control outputs for all kinds of actuators (relay, logic, analog or motor-positioner outputs); it also provides two user logic inputs and three alarm relay outputs. A watch-dog supervisory function ensures automatic reset of the device. A serial RS485 interface with Modbus protocol allows communication with a supervisory computer.
