KMC Controls BAC-4000 series, Installation, Operation, And Application Manual

Page: 9 / 128

Short-circuit protected
Loads up to 10 mA at 0–12 volts DC
8-bit PWM digital-to-analog conversion
Relay outputs
Relay outputs are configured to represent BACnet binary objects. The
outputs control on/off valves, speeds for three-speed fans, fan start circuits,
or other equipment that requires an on or off input signal.
All relay outputs are normally open, SPST, Form “A” relays
1 Ampere maximum per relay at 24 volts AC or DC for each output.
Maximum for all relay outputs is 3 amperes (72VA).
