Single loop 1/16 DIN controller
650/1250/1250 series
- With automatic tuning algorithms to control heating, cooling, and combinations of the two
- Customizable display - set point programmer - logic control function block
Notes:
LV = 20...27 VAC/DC power supplyMain applications of the Gefran 450 controller:
- Packaging machines
- Packing machines
- Labelers
- Food processing lines & machines
- Laboratory machines and ovens
- Electrical heaters for industrial heating
Flex-view display
The information on the display (colors, messages, alarms, help in line) can be customized, making the HMI more efficient:
Operator messages are configurable. They can be activated by numerous process events, such as: alarm limits attributed to the main variable, to the setpoint, to the remote setpoint, to reading of load currents; from digital inputs, from Function Block outputs.
The colour combination on the display can be customized. Model 650: the standard colors of the PV-SV displays are White-Green. A different color combination can be evaluated on request.
Help in Line messages for product configuration (English)
Maximum clarity of system diagnostics messages (English)
Colour of the device frame can be customized 
Easy setup
Controllers are configurable from the faceplate in very few steps 
Configuration with GF Express (from PC) even with the controller off
Configuration with portable configurator (Zapper)
Can be done by non-experts! Saves time in multiple setup of controllers with the same configuration.
Logic control block
With 16 Function Blocks (AND – OR – NOT – TIMER), you can develop (program) applications and assign external events (logic inputs) with events or internal states to the PID control function (alarms, setpoint state, etc.). This simplifies the control system by integrating multiple HW components in a single device. It also maintains the advantages of single-loop PID control.
Setpoint Programmer Block
Valve Positioner Block

Monitoring of energy consumption & preventive maintenance
Energy Monitor lets you display, totalize, and save energy consumption (for example, KWh) of a single device or of a single heating zone.
Maintenance Minder prevents system downtimes and production losses
