R2-50 can operate as a single or double loop controller, and allows a range of control strategies to be applied . It can also be used as a motorised valve controller . It allows set point programming for complex thermic profiles and operating timetable for automatic start/stop. Inside the device a real time clock option can be added with a week programmability ( day of week , hour , minute ). No battery is required for time retention . Over 1 month period is guaranteed during power off.
This feature makes very easy and reliable to program thermal cycles whose time evolution is independent from external timing sources.
Thermal cycles are completely programmable via Modbus commands.
R2-50 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. Interfacing the device with HMI touch panel is possible through modbus protocol.
Up to 400 modbus gates can be used to control the device .
