Danfoss AK-PC 772A

18 Capacity controller RS8HF102 © Danfoss 2017-07 AK-PC 772A
Extension module AK-XM 103A
Function
The module contains :
4 analog inputs for sensors, pressure transmitters, voltage signals
and contact signals.
4 analog voltage outputs of 0 - 10 V
Supply voltage
The supply voltage to the module comes from the previous
module in the row.
Supply voltage to a pressure transmitter can be taken from either
the 5 V output or the 12 V output depending on transmitter type.
Galvanic isolation
The inputs are galvanically separated from the outlets.
The outlets AO1 and AO2 are galvanically separated from AO3 and
AO4.
Light-emitting diodes
Only the two top LED’s are used. They indicate the following:
• Voltage supply to the module
• Communication with the controller is active (red = error)
Max. load
I < 2.5 mA
R > 4 kΩ
