Gefran 1250 Controller – Programmer

The Gefran 1250 is a PID process controller, 48×96 mm (1/8 DIN), 80 mm depth, designed for local temperature and thermal process control in automation panels. It features an LCD display with PV, SV, F indication, bargraph for power/current/valve position, four keys, and a removable front panel for maintenance or replacement.

Process Inputs

Main input supports thermocouples J, K, R, S, T, C, D, RTD Pt100/JPt100, IR ES1B, and linear signals 0–60 mV, 0–1 V, 0–5 V, 0–10 V, 0/4–20 mA. Scaling is configurable from -1999 to 9999, with decimal point selection and sampling time of 60 or 120 ms.

Outputs and Control

Supports single-loop PID, ON/OFF, heat, cool, heat/cool, and open/close control for motorized valves without feedback. Output options include relay (5 A / 250 Vac), logic 24 V for SSR, triac 12–240 Vac / 2 A, continuous 4–20 mA, or analog retransmission 0–10 V and 0/4–20 mA.

Programming and Diagnostics

Setpoint programmer allows up to 4 programs and 12 steps with ramp, hold, consents, and event outputs. Up to 4 alarms, LBA for loop break, HB for load interruption or partial load failure, and SSR alarm for output short circuit are available.

Communication and Load Monitoring

Optional RS485 communication with Modbus RTU up to 115200 bit/s. Up to two CT 50 mAac inputs for load current measurement and energy monitoring based on nominal power or rms current via CT.

Typical Applications

  • Industrial ovens, dryers, and thermal zones
  • Extruders and injection molding machines
  • Packing machines with SSR or contactor control
  • Electric resistance control with HB diagnostics
  • Motorized open/close valves in thermal loops

Operating Conditions and Standards

Power supply: 100–240 Vac/Vdc or 20–27 Vac/Vdc. Operating temperature: -10 to +55 °C. Front panel protection: IP65. Installation category II, pollution degree 2. Compliance: EMC 2014/30/EU (EN 61326-1), LVD 2014/35/EU (EN 61010-1). UL listed as process control equipment per UL 61010-1.

Overview

Large LCD display with customization of colors assigned to PV, SV and F display, of color of plastic faceplate, and of logo.

Graphic display of power, output current or valve position.

Scrolling alphameric display of 25 messages (32 letters each), completely configurable and savable, in three languages.

Thanks to language selection and clear scrolling messages for diagnostics, alarms, and process state, the controller speaks the user’s language.
