Analog Input Module
The Analog Input Module is a generic unit interfacing with LONWORKS™ systems, that
use a free topology wiring scheme supporting star, loop, and/or bus wiring.
The Analog Input Module contains two isolated groups of each two analog input channels,
for processing ± 0-10 VDC or ± 0-25 mA current signals. The analog inputs can be logically
connected via a network to different input/output modules and data visualization software.
For each channel the module offers two user-settable alarm levels and input scaling.
All states are indicated by LEDs. The module provides one dedicated power loss relay with
SPST contact for activation of external alarm devices.
Network configuration data is customer specific and is programmed into nonvolatile
memory.
