C-Bus™ Input Units and Relays
Class 1250
General Input Unit
Four-Channel General Input Units 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. Configuration options include selectable input types, eight adjustable decision
thresholds per channel, definable actions, selectable filtering, broadcast rates, and a
separate hysteresis value per channel.
• 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
• Control functions include load switching, dimming, trigger applications, enable control applications,
and measurement applications
• Includes 120 V/24 Vdc power pack
• Dimensions: 5.67 in. (144mm) wide x 2.60 in. (66mm) deep x 3.35 in. (85mm) tall
• Compatible with all Clipsal devices and the Square D Powerlink NF3000G3C controller
Bus Couplers
Bus Couplers provide an interface between dry-contact mechanical switches and the C-Bus
network. Available in two-and four-channel models, the bus coupler is small enough to be
used in restricted spaces such as wall boxes with existing switches. Configuration options
include standard control functions such as ON/OFF, toggle, dimmers, and timers.
• Provides two or four non-isolated inputs for external voltage-free mechanical switches. Two-channel
units feature independent remote LED outputs
• Two-way removable terminal block for the C-Bus connection
• Receives data and power over a network, so it does not require power packs or line voltage
connections
• Scene capabilities
• 2.2”(L) x 1.9”(W) x 0.7”(H)
• Compatible with all Clipsal devices and the Square D Powerlink NF3000G3C controller
Relays
C-Bus Relay Units are intended for switching resistive, inductive, fluorescent and
incandescent low-voltage loads. Relay units are designed to be mounted in suitable DIN
style enclosures. Relay units feature:
• Local toggle buttons to allow individual channels to be toggled
• Remote ON and OFF facilities permitting all channels to be turned ON or OFF without C-Bus
Network communications
• Two (2) Convenient built-in C-Bus network connectors (RJ-45)
• LED Indicators to show the status of the network and the unit
• Units available both with and without a 200ma power supply on-board.
• Compatible with all Clipsal devices and the Square D Powerlink™ NF3000G3C controller
Changeover Relay
C-Bus 2A Changeover Relays are designed to operate three-speed motors and two-way
motor control devices. Some of their most common applications include operating
motorized blinds, shutters, curtains and skylights (open/closed) where they provide a much
simpler alternative to traditional and obtrusive relay interlocking systems.
• Four (4) isolated independently operating relay channels
• 120 Vac and 277 Vac units
• 2A motor rating
• Dimensions: 5.67 in. (144mm) wide x 2.60 in. (66mm) deep x 3.35 in. (85mm) tall
