To provide a 4-20 mA output signal when 3-15 PSI is applied to an on board transducer. This signal is then fed back into the inverter for control or monitoring in HVAC applications. The card also. provides (2) separate voltage to current converters, designed to provide 4-20 mA output signals when used with the GP10 and VG10 FMA and FMP output signals (0-10 VDC).
3-15 PSI (22 PSI max.) air supply
FMAI: 0-10 VDC signal from GP10 and VG10
FMPI: 0-10 VDC signal from GP10 or VG10
FMAO: 4-20 mA into a max load of 500 ohm
FMPO: 4-20 mA into a max. load of 500 ohm
C1-11: 4-20 mA output from back to inverter.
