Commercial Gas Detection
420I
Communicates digitally with Vulcain transmitters within a true daisy chain network, converting the digital signals to analog outputs. Quick Specs Power requirement: 17-24 VAC, 24-38 VDC, 500 mA Size: 8.4 (H) x 8.6 (W) x 2.5 (D) in.
The 420I communicates digitally with Vulcain transmitters within a true daisy chain network, converting the transmitters’ digital signals to analog outputs. This allows each transmitter to provide a 4-20mA signal to a BMS from one central location. The unit can accommodate up to eight transmitters installed at distances of up to 2 000 feet from the unit.
To avoid expensive DDC hook-ups and BMS software upgrades, the unit even comes with internal logic that will provide averaging/minimum/maximum reading for up to 16 transmitters.
