Four-Channel General Input Units are DIN-rail mounted devices that
measure TTL digital and real-world analog quantities and generate messages about the
measurements to the C- Bus network. By acting as an interface with various external
sensors, the general input unit enables integration of the C-Bus network with a variety of
system types, such as those for HVAC and for power monitoring.
Conguration options include selectable input types, eight adjustable decision thresholds
per channel, denable actions, selectable ltering, broadcast rates, and a separate
hysteresis value per channel.
General Input Unit
Product Features
• Measures TTL digital quantities including
voltage, current, or resistance from external
sensors such as light level, pressure, and
temperature
• Four channels of input, each with an
adjustable hysteresis value, eight decision
thresholds, and a software-selectable input
value transformation in the form y = ax +b
• Input channels are compatible with a range of
third-party sensors
• Look-up table with interpolation
• Capable of threshold switching or
broadcasting values onto the network
• Control functions include load switching,
dimming, trigger applications, enable control
applications, and measurement applications
• Measures input signals up to 10 Hz and has
an adjustable input-signal lter to reduce
susceptibility to impulse and noise
• Supplies 250 mA to external sensors
• LEDs indicate the status of the network
at the unit and the unit’s power and data
transmissions
• Software-selectable network burden and
C-Bus system clock
• Standard built-in C-Bus network connectors:
(2) RJ-45
• Non-volatile memory stores operating status
for recovery from a power outage
• Includes 120V/24V AC power pack
Distributed Intelligence
• Compatible with all C-Bus devices and the
Powerlink
®
NF3000G3C controller
• Easily congured with the C-Bus Toolkit
