5.1.8 Analogue Inputs
The analogue inputs are connected to the CI1376 connection interface board as illustrated in
Figure 5-10.
The inputs are:
• Analogue Channel 1-3 - three differential DC analogue inputs, P (pin-1) is the positive and
N (pin-3) is the negative terminal, and pin 2 is GND.
Maximum voltage: ±15V
Input impedance: 10kΩ
• Temp Indoor and Outdoor - temperature measurement inputs with interface to an LM35
temperature sensor.
Maximum voltage: ±15V
Input impedance: 10kΩ
• AC Level - AC level measurement input. Intended for use with a battery eliminator to moni-
tor the mains voltage.
Maximum voltage: 24Vpp
