Product Overview

The Gefran 2400-0-W-4R-0-1, ordering code F028816, is a fast 1/8 DIN indicator and alarm unit designed for high-speed acquisition, display and monitoring of industrial process signals. Typical applications include pressure, force, position, temperature and differential measurement systems where rapid signal changes and configurable alarm handling are required.

Main Features

• Fast microprocessor-based indicator and alarm platform.
• Two main configurable analog inputs for supported strain-gauge, potentiometer, linear, thermocouple and RTD signals.
• Two auxiliary analog inputs for supported linear signals.
• Four relay outputs associated with the 4R configuration.
• Five-digit process display and six-key front operator interface.
• Peak, minimum peak and peak-to-peak monitoring functions supported by the 2400 platform.

Technical Specifications

Compatible System and Applications

This unit is intended for panel-mounted measurement and alarm systems using supported process sensors and transmitters. Sensor type, excitation requirements, scaling range and wiring must be configured for the actual application. It should not be connected solely on the basis of the 2400 family designation.

Maintenance and Replacement Notes

Before replacement, isolate the supply and document all terminal connections and configuration parameters. Confirm the input signal, relay contact assignments, supply rating and panel cutout. Transfer settings only after confirming that the replacement carries both model 2400-0-W-4R-0-1 and ordering code F028816.

Related Models

Other 2400 configurations may differ in analog retransmission, communication interface, alarm expansion, output type or supply option. The Gefran 2500 is a 1/4 DIN PID controller for pressure and force control, while the 2301 family provides configurable closed-loop control rather than indicator-only operation. Related models are provided for family reference only and are not automatically interchangeable.

Inquiry and Supply Notes
