The Honeywell Anayltic’s 420I communication transmitter communicates digitally with Vulcain transmitters within a true daisy chain network, converting the digital signals to analog outputs.
The 420I communicates digitally with Vulcain transmitters within a true daisy chain network, converting the transmitters’ digital signals to analog outputs. This allows each communication 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.
