Product Overview

The Gefran 650-D-R00-00000-0-G, ordering code F065795, is an advanced 1/16 DIN PID controller for temperature and general industrial process regulation. Unlike the older 600 platform, the 650 provides a large configurable LCD interface, scrolling diagnostic messages and guided setup functions. This exact configuration uses a low-voltage 20–27 VAC/VDC supply.

Main Features

• Large LCD display with configurable process-value and setpoint colors.
• Scrolling messages for alarms, diagnostics and process states.
• Guided configuration with parameter copy and paste support.
• Advanced PID tuning and multiple application function blocks.
• Preventive-maintenance functions including energy and load-switching counters.
• Logic and relay output arrangement associated with F065795.

Technical Specifications

Compatible System and Applications

The controller is suitable for compact control panels in heating, plastics, packaging and process machinery. The low-voltage supply must be observed carefully: it must not be connected directly to a 100–240 VAC supply. Sensor input, control-output destination, alarm assignments and polarity of DC circuits must be checked before commissioning.

Maintenance and Replacement Notes

Back up parameters and record the firmware and application configuration before replacement. For DC supply operation, verify polarity and protective devices. For AC supply operation, confirm that the available voltage falls within the documented low-voltage range. Check the logic-output interface before connecting an external solid-state relay.

Related Models

650-R-R00-00000-0-G, ordering code F065796, has a different output arrangement. The 650-D-R00-00120-0-G adds further option positions, while 650-D-RR0 and 650-D-RRR configurations provide additional outputs. The 1250 and 1350 share controller-generation features but use different panel dimensions. Related models are provided for family reference only and are not automatically interchangeable.
