Customizable temperature controller
x400 Controller
GEFRAN
Manufactured using SMT, the 3400 provides a complete operator interface with IP54 level of protection (IP65 with faceplate cover).
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, setpoint, bargraphs 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 linearisation.
A second auxiliary analogue input is available for remote setpoint linear signal, potentiometer valve position feedback or input from a current transformer.
With a digital input it is possible to select between two preset setpoints or switch between local and remote setpoint.
With three isolated digital inputs, it is possible to select one of four setpoint programmes or supply a start, stop and reset signal, or select local/remote, auto/manual or hold.
