Notifier nion-2C8M discrete network input output note
NION-2C8M (2-Control/8-Monitor) is a general-purpose
module for monitoring inputs and controlling outputs. It

BCI) product lines. Like all UniNet components, it is
based on LonWorks technology.
The NION-2C8M provides eight supervised inputs for dry
contacts plus two SPDT relay outputs. Each input has alarm
and trouble LEDs to indicate which input is active or in open
circuit. Similarly, each output has an LED to indicate relay
activity. Each input and output has a unique address. The
inputs are supervised with an end-of-line resistor. Shorting
the circuit will cause an alarm and opening the circuit will
cause a trouble. The NION-2C8M also has LEDs for status,
indicating normal operation, and for network binding,
indicating proper network configuration.
All points can also utilize a scheduling plug-in application
on the network which provides tools for input enabling and
disabling and output activation and deactivation on a userdefined
The NION-2C8M contains the transceiver and network
communications software. It accepts and sends
standard UniNet 2000 messages.
To provide reliable operation, the NION-2C8M employs
several protection methods. Transient protection
is provided on all terminals, and the network connection
