Product Overview

The Gefran 2500-0-0-0-W-0-1, ordering code F028677, is a 1/4 DIN single-loop PID controller developed for pressure, force, temperature and other fast-changing industrial processes. Gefran also identifies this exact controller configuration as a component of its W0 diathermic-oil pressure-control set. This page covers the controller only unless the quotation expressly includes the matching transducer, cable and mounting accessories.

Main Features

• Single-loop PI or PID process-control platform.
• Main inputs designed for supported strain-gauge, potentiometer, linear, thermocouple and RTD signals.
• Support for differential measurement and auxiliary analog signals at series level.
• Four configurable relay outputs.
• Triple five-digit front display and configurable bar graphs.
• Automatic calibration support for compatible six-wire strain-gauge systems.

Technical Specifications

Compatible System and Applications

The controller can be integrated into pressure, force, differential-pressure and temperature systems when the sensor signal, excitation, scaling and output circuits match the configured hardware. In a W0 set, the complete system may also contain a W3-series oil-filled pressure transducer, C08WLS cable and SF18 bracket; these components are not automatically included with a standalone controller.

Maintenance and Replacement Notes

Save PID parameters, calibration data, alarm values and input scaling before replacement. Check the sensor bridge wiring, excitation voltage, relay assignments, panel dimensions and supply terminals. Calibration should be performed with the actual sensor and process range after installation.

Related Models

2500-0-0-0-W-0-0 differs in the final configuration code. Models such as 2500-0-0-0-W-2-1 and 2500-0-0-0-W-3-1 have different communication or option positions and carry different F-codes. The 2400 is an indicator/alarm platform rather than the same pressure-control configuration. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes

Specify whether the inquiry is for F028677 alone or for a complete pressure-control set. Provide the controller nameplate, sensor model, pressure range, cable requirement and required condition. Suggested pricing applies to the controller upload reference only and does not confirm that a transducer, cable, bracket or other system component is included.
