Microprocessor temperature monitor system for electrical transformers with 2 inputs for PTC probes
[/text_output][gap size=”45px” id=”” class=”” style=””][text_output]- Two PTC inputs with fixed temperature level
(see PTCK series sensors) - Possibility to connect up to six PTCK sensors in line for each channel (max. 1.5 Kohm for channel)
- Interconnections among the relays contacts are shown in schema
- Visualization correct working state
- Visualization pre-alarm and alarm state
- Intrinsic sure protection system with relays always on and signalling with switch off relays
- Delay at power on (1 sec. about) for a direct connection with a shut down device
- Assembly on rear panel by quick coupling with Din rail
- Power supply (220 ÷ 240) Volt AC 50/60Hz
- Tropicalization (optional)
