R1-120A-I

Multiloop controller with 6 0/4-20 mA input channels

The R family includes a series of multiloop controllers well suited for all applications that require control of a large number of temperatures; all controllers can be mounted on a DIN rail and can be linked to a local operator panel (F1-10).
Different models are available for reading Pt100, thermocouples or linear signals (V/mA); for each loop it is possible to configure control type (heat, cool, heat/cool, ..), output type (on/off, time proportional, valve, ..) and alarm strategy or to run a auto-tuning procedure; furthemore it is possible to limit the energy conumption during start-up by programming a proper sequence of activation of PID loops.
R2 models have differential isolated channels that gives another substantial improovement to the features of these devices , expecially in noisy industrial environments.
A RS422/485 serial interface with Modbus (ASCII or RTU) protocol allows link of many controllers to the same master unit (PC, PLC or operator panel). 

Multiloop temperature controller for DIN rail mounting; 6 analog inputs for 0/4-20 mA; accurate readings without need of calibration; up to 6 PID loops; heat, cool or heat/cool control with various output types: on/off, time proportional, analog (with addition of C1-10 external module) or for motorized valve control (open/close); PID autotuning algorithm; programmable activation sequence to limit the energy consumption during start-up; dedicated interface for connection with a local operator panel (F1-10); RS422/485 serial interface with Modbus (ASCII or RTU) protocol; a common supervision of many controllers can be provided by any commercial SCADA software with modbus libraries or by HMI touch screen operator panels.
