Description:

DRR 245 is the DIN rail mounted multifunction controller. One analog input configurable by parameter for up to 18 different sensors/signals. Three outputs configurable by parameter: two as relay (also as Open/Close logic for motorised valves control), one as SSR, 4…20mA, 0…10V signal (both for command or re-scalable retransmission of process/setpoint). The switching power supply with extended range 24…230Vac/Vdc does not require any jumpers setting. Control modes: On/Off, PID + Autotuning, Heating/Cooling PID with neutral zone.

Software features include the launch Tuning and the selection of setpoints by digital input, the optional manual reset of output by frontal keyboard ("Limit controller"), Latch-on function for sensors calibration (including load cells), a programmable cycle of 3 steps . Serial communication RS485-ModbusRTU and load monitoring function (Loop Break Alarm) with amperometric transformer TA. Optional Memory Card to copy all parameters, available also with internal battery therefore not requiring to power up the unit.

Software application LABSOFTVIEW for Windows enables setting and monitoring of parameters on PC.

Device is UL-CSA approved for North-American market.
