Heating elements control
Plastics extrusion, injection moulding
Load cells control
Motorised valves control
Remote control via RS485
Controller 48x48mm, 2-4 setpoints, frontal extraction of electronics. One analog input configurable by parameter for up to 18 different sensors/signals.
2-4 Outputs configurable as relays(also as Open/Close logic for motorised valves control), 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 2-4 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 . Optional features are the serial communication RS485-ModbusRTU and load monitoring function (Loop Break Alarm) with amperometric transformer TA. Sealing IP65 with frontal gasket.
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.
