Digital Input Module
The Digital 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 Digital Input Module contains two groups of four optocoupler isolated digital inputs,
each group with separate common signal ground. It is used for processing binary and
digital values, e.g. switch signals.
All input 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.
