420I Converter:
• Easy installation through daisy chain hook-up (RS-485)
• Provides dedicated 4-20mA outputs for up to 8
transmitters or either Min/Max/Avg
• Fully compatible with the 201T and 301D2 series as
well as the SQN8X
• Communicates with transmitters at distances of up to
2000 feet
The 420I communicates digitally with transmitters (201T, 301D2, SQN8X, etc.), within a true daisy chain network, to convert 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 8 transmitters installed at distances of up to 2000 feet from the unit.
To avoid expensive DDC hook-ups and BMS software upgrades the unit even comes with internal logic that will provide either minimum/maximum/ average reading for up to 16 transmitters.
