Product overview
Panel temperature controller
A wide front panel with four side keys, a fixing bracket and a vented rear housing.
Overall dimensions: 160 × 80 × 110 mm. LED numerical and bar indication for PV and SV.
Multi-segment control and alarm indication
External measurement inputs include thermocouples, three-wire Pt100 and two-wire current transmitters. Alarm functions include upper and lower limits, deviation and control-loop break detection, with hysteresis settings.
Panel and case envelope
Overall width × height × depth: 160 × 80 × 110 mm.
Configuration and selection
Measurement input connections
The illustrated 36-terminal configuration separates measurement input, transmitter feed and control output. Other case formats use different terminal arrangements.
