Description
XBN electronics are integrated with system circuitry
(eliminating the need for separate boxes for wires,
transducers, etc.) and are housed in durable cases.
Modules plug in and lock into position.
DC, AC, Dry Contact, and Pulse
32 Binary Inputs (software-configured: light ON =
either closed contact/voltage absent), N2 Transmit,
N2 Receive, Power, and Error (sanity circuit reset,
check sum, RAM test result)
Each input is balanced differentially, with a high
input impedance (significantly reducing amperage)
and high level of isolation from noise and
transients. Inputs withstand 120 VAC RMS of
normal mode voltage.
The XBN latches and holds any valid data changed
from an input point; further data changes are
ignored until the first-detected change has been
reported to, and acknowledged from, the NCM.
Suppresses COS, reporting capabilities on a per
input basis. While COS reporting is disabled, the
NCM can still request point status without re-
enabling the COS report functions.
Programs the XBN to ignore transient or intermittent
changes by requiring consecutive identical input
data before determining the current state.
For each status input, detects and totals transitions
for pulses of less than or equal to 10 Hz (each
pulse yields two transitions). When requested by
the NCM, the Accumulator releases the number of
valid signal transitions (up to 65,535 before rolling
over).
Purpose
Simple to install and service; casing prevents
physical and ESD damage in addition to shielding
electronics from induced noise.
Interfaces a high concentration of binary devices;
flexibility to retrofit existing devices.
Determine module status by visual inspection.
The XBN withstands high levels of noise, especially
common mode noise. Enables mixed input and
output lines through a conduit, when allowed by
local electrical codes.
Report COS for alarm analysis or program
triggering, and to notify operator(s).
Prevent constant COS reports from specified points
(e.g. fluttering airflow switch).
Helps prevent false alarms or erroneous counts in
accumulator points.
Permit monitoring of devices that transmit
frequency signals.
