Analog Inputs
The NMC-PRO can contain a maximum of 4 analog input cards. Each card consists of 11
inputs; in total 44 analog inputs are available per local controller. Expansion boxes can
contain a maximum of 3 analog input cards (Maximum amount of analog inputs in a single
network is 256). The Analog input card enables defining each input’s function using jumpers.
The card supports the following options:
 Inputs 1 – 10 can be connected to temperature sensor, 0 – 5VDC sensors (for example
humidity sensors) or 4-20 mA sensors (for example CO
2
sensor).
 Input 11 can be connected to all three options mentioned above, and in addition to
the wind direction sensor.
The analog input consists of 12VDC, the 12VDC can be used to drive sensors (for example:
humidity sensors) with a maximum current of 100mA.
NOTE: Make sure not to overload the 12VDC supply as this might damage the analog input
card.
The Analog inputs card consists of surge and lightening protection circuits and does not
require additional external protections.
Jumper selectors for
