It is obvious from the specimen configuration that all the modules have sufficient
outputs when an external power supply is used. When a PoE supply is used, the power
output is insufficient for all the modules, which results in automatic decrease in
backlight level, active output current supply, volume and LED intensity.
Some modules need a specific power output for their specific activities: the I/O
module, e.g., requires 0.13 W for relay closing (not included in the minimum
consumption).
Keypad Module
The Keypad module ( ) is one of the elements Part No. 9155031 2N
®
Access Unit
and is used for a numeric access to the system.
The module contains two bus connectors for 2N
®
Access Unit
These two connectors are fully interchangeable and can be used either as inputs
from the basic unit or outputs to other modules.
If this module is the last one on the bus, one of the connectors remains
unconnected.
The module package includes a 220 mm long interconnecting cable.
