Installing A Mini-At Without An Instrument Drive; Low Frequency Meter Pulse Input; Rsi Board - Honeywell Mini-AT User Manual

Installing a Mini-AT without an Instrument Drive

The Mini-AT can be configured to accept low frequency meter input pulses directly from a meter or
Model 210/212 pulse transmitters (or any other low frequency pulse source)
Alternatively, the Mini-AT can be configured to accept high frequency pulses from turbine meters input, but
requires the High Frequency Input Board (HFI Board) instead of the RSI board (see Figure 6).

1) Low Frequency Meter Pulse Input

The Remote Switch Interface Board (RSI board, p/n 40-2016), must be installed if the Mini-AT is to
receive input pulses from a Model 210/Model 212 Pulse Transmitter or a low frequency pulse from a
gas meter. Figure 5 (below) and Table 1 (on the next page) provide wiring information for the RSI and Pulse
Transmitters.
