Feferan

DESCRIPTION:-
The faceplate has a membrane keypad with 6 keys, a backlit LCD display that is available also with large dimensions (model 4400) that displays the process variable, set point, barographs of the percentage output power and the deviation and indication of the alarm and controller states. The main input for the control variable is universal and gives the possibility to connect a wide range of sensors such as thermocouples, resistance thermometers or mV signals even with custom linearization.
A second auxiliary analogue input is available for remote set point linear signal, potentiometer valve position feedback or input from a current transformer.
With a digital input it is possible to select between two preset set points or switch between local and remote set point.
With three isolated digital inputs, it is possible to select one of four set point programmer or supply a start, stop and reset signal, or select local/remote, auto/manual or hold.
The instrument has up to four outputs, each one factory configured, according to the order code, as relay, isolated logic, isolated analogue or interface for MD81 expansion unit output.
The output functions are configurable from the faceplate.
