The Gefran 800 V is a configurable controller for processes involving solenoid- and motorized valves. It is preferred in applications with limited space.
This instrument has up to 4 relay or logic outputs, 2 of which will be dedicated to the open/ close valve functions and up to 2 isolated analogic outputs, in voltage or current.
Every function is configurable from keyboard: available functions are control output (open/close valve); alarm output; timer controlled output; digital input repetition; retransmission of process value, setpoint, deviation, alarm setpoint or valvue read from digital communication.
- Universal input configurable from the faceplate
- Acquisition of the input signal every 120msec ; resolution 30000 steps
- 2 control outputs: relay, logic or analogue with open/ close valve function
- 3 configurable alarms
- 2 analogue outputs (setpoints retransmission)
- 2 digital inputs with configurable function
- Auxiliary input for valve position potentiometer feedback
- Heater Break or shortcircuit probe alarm
- Self and Auto- tuning , Soft- start, Local/ Remote, setpoint, Auto/ Man
- Multiset function, timer set ramp
