Gefran 600 Temperature Controller
The Gefran 600 is a microprocessor-based temperature and process controller, 48×48 mm (1/16 DIN), designed for local loop control in automation panels. The front panel is rated IP65 and features dual 4-digit displays for PV/SV and output status LEDs.
Process Inputs
The main input is universal and configurable from the front panel, with no external shunts required. Supported sensors include thermocouples J, K, R, S, T, B, E, N, L-GOST, U, G, D, C, RTD Pt100/Jpt100, PTC, NTC, and linear signals 0/4–20 mA, mV, V. Measurement range is -1999 to 9999, with 32-segment custom linearization available.
Control and Outputs
Control modes include On/Off, P, PD, and PID for heating/cooling, with self-tuning, auto-tuning, soft-start, bumpless Man/Auto transfer, and power limitation. Output options: relay 5 A / 250 Vac, logic 24 Vdc for SSR, triac 20–240 Vac / 1 A, opto-isolated MOS, continuous 0–10 V or 0/4–20 mA, and 12-bit analog retransmission.
Load Monitoring and Communication
Auxiliary CT input (50 mAac) is available for heater break alarm or load current monitoring. The isolated digital input can be used for setpoint selection, Man/Auto, alarm reset, hold, or software on/off. Serial communication via RS422/485 supports GEFRAN CENCAL and Modbus RTU protocols.
