Accessories - F / I ( 2 ) Board

The F / I ( 2 ) Board converts the frequency produced by a standard GL Flow Turbine into a 2 wire, 4 – 20 mA signal.

4 mA represents zero flow and 20 mA represents full flow, or can be scaled to a lower value if required (subject to the specifications, below).

Setup is simply achieved by adjusting 4 rotary decimal switches to the frequency corresponding to the maximum flow rate.

Specification

Supply Voltage	8 to 30 V ( regulated D.C. Supply )
Input sensitivity	5mV r.m.s at 100Hz
Frequency range	5Hz – 10KHz
(Frequencies < 5Hz will produce a 4 mA signal)
