Rated for RS232 integration and relay-based control, the COMET H4331 monitors temperature from Pt1000 probes and external sensor inputs. Serial connectivity allows integration with data acquisition systems and industrial controllers, while onboard relays enable direct switching in response to measured temperature conditions from connected probes.
Available to back order. ETA will be 3 - 5 weeks.
Temperature transmitter for Pt1000 sensor with two relay outputs. Outdoor, indoor use.
For external Pt1000 temperature probe (sold seperately). Three two-state inputs.
