Input units create a response (or series of responses) via programmed C-Bus Output Units, based on a particular realtime event.

A wide range of C-Bus Input Units are available to suit specific application requirements. The C-Bus product range offers a selection of input units.

C-Bus General Input Unit

Part Codes: E5504GI

The C-Bus General Input Unit incorporates 4 input channels. Used to trigger a C-Bus group address or broadcast a message on the C-Bus Network in response. Provides an interface between a C-Bus Network and third-party products.

  • 4-channel general analogue/digital input unit, DIN rail mounted
  • 8M DIN modules wide
  • Dimensions 144mm x 85mm x 65mm
  • Used to interface a C-Bus system to third-party products, such as light level sensors, current sensors, temperature sensors, CO2 detectors, differential sensors, pressure sensors, flow rate sensors, moisture probes, etc.
  • Designed to either trigger the state of a C-Bus group address as a function of input level or broadcast a message on the C-Bus network, representing the input level
  • Maximum of 10 units on a single C-Bus network
  • Can be used to measure analogue values (0-1V, 0-5V, 0-10V, 0-20V, 0-20mA, 4-20mA, 500 ohm, 1k ohm, 3k ohm and 10k ohm thermistor inputs)
  • Requires a 24V d.c. connection (power pack included)
  • Units draw 18mA from a C-Bus network

C-Bus DIN Rail-Mounted Auxiliary Input Unit

Part Codes: L5504AUX

Provides 4 independent input channels to facilitate access to C-Bus via a voltage free switch mechanism.
DIN Rail mounted C-Bus 4 channel Auxiliary input units permit voltage free contacts to be connected to C-Bus, such as Clipsal 30 Series mechs, limit switches, and weatherproof switches. The unit can be programmed like a C-Bus Wall Switch to achieve Timer, Dimmer or Toggle switch functionality. The Auxiliary Input Unit is ‘Learn Enabled’ and powered from a C-Bus network.

  • Learn Enabled
  • DIN Rail mounted
  • Four Channel Unit
  • Permits voltage free switches to be connected to C-Bus
  • Programmable like a C-Bus switch, achieving the same functions as Timer, Dimmer or Toggle switches
  • Powered from the C-Bus
  • Requires 18mA at 15 – 36VDC for correct operation

C-Bus Current Measurement Unit and Current Transformer

Part Codes: 5504CMU

DIN Rail mounted C-Bus Current Measurement Units measure and report over C-Bus a circuit’s instantaneous electrical power consumption.
Energy usage can be displayed on C-Bus devices such as the 6.4″ colour touch screen controller, Wiser Home Control, and Schedule Plus software.

  • Measures and reports a circuit’s instantaneous electrical power consumption over C-Bus
  • Current monitoring via a split core current transformer (CT)
  • 4-channel unit (measure up to 4 electrical circuits per unit)
  • Display energy use on C-Bus 6.4″ Colour Touch Screen, Schedule Plus, HomeGate software and Wiser Home Control
  • Raises C-Bus alerts and warning messages on predefined thresholds
  • Controls electrical devices based on predefined thresholds (load shed)
  • Can provide confirmation that electrical devices are operating as expected
  • DIN rail mounted, 4M wide
  • C-Bus supply voltage: 15-36V d.c. @ 18mA (does not provide power to the C-Bus network)
  • CT is split core type and measures current between 0-80A (supplied separately)

C-Bus Bus Couplers

Part Codes: 5104BCLWE

These devices allow the connection of voltage free mechanical switches into the C-Bus system.
They are used to interface up to 4 standard voltage free mechanical switches, including latching and toggle switches, to C-Bus. The unit is designed to fit into a standard wall box.
