Expansion modules of the CIB installation bus

CIB® – Foxtrot installation modules

The CIB® (Common Installation Bus) extends the Foxtrot system with a range of modules designed specifically for installations in buildings, technologies, and energy systems.

Unlike classic PLC peripherals, CIB is not bound by PLC I/O standards.
It is designed for real-world installations: distributed, combined, and evolving over time.

CIB is where a PLC becomes a system for buildings and energy.

Modules for every part of the installation

CIB modules are available in several designs depending on their place of use:

DIN-rail modules

  • highest number of inputs and outputs

  • manual control buttons for commissioning and service

  • ideal for control cabinets, lighting, blinds, and technologies

Embedded modules

  • small modules for installation boxes or devices

  • typically 1–2 relays, combinations of inputs and outputs

Wall-mounted controllers

  • push-button and touch versions

  • often with integrated sensors (temperature, humidity, CO₂)

  • variants with display or RFID

Outdoor modules

  • protection rating IP57 and higher

  • weather, lighting, and environmental sensors

A different principle than PLC I/O

CIB modules operate on a different logic than classic PLC peripherals:

Fixed factory-set address

  • no configuration during installation

  • address is printed on the module

Universal AI/DI inputs

  • resistance measurement using internal measuring current

  • no external power supply required

  • digital contacts and resistive sensors on a single input

Combination of functions in one module

  • relays + inputs

  • inputs + integrated sensors

  • maximum functionality with minimal wiring

Specialized modules without compromise

CIB also includes a wide range of specialized modules:

Lighting control

  • 230 V AC dimming (including challenging LED loads)

  • DC control of LED strips and chips

  • CIB ↔ DALI / DALI-2 conversion

Building energy

  • fast three-phase power meters / power quality meters

  • measurements every 200 ms

  • ideal for sub-metering and EMS

Electromobility

  • controlled EV charging

  • PWM control on the CP contact (CCS)

Why CIB makes sense

CIB is not “just another bus”.
It is an installation ecosystem that makes it possible to:

  • build the system gradually

  • combine control, measurement, and energy management

  • minimize cabling and errors

  • move intelligence closer to the point of action

CIB is what gives Foxtrot its depth and breadth in buildings and energy.

Where to continue

With the CIB® bus, it pays not to rush straight to the catalog.
Its true strength is best understood in the application-oriented sections—based on what you want to control, not which module you are looking for.

👉 CIB use in buildings
👉 Lighting and comfort control
👉 Building energy and energy management
👉 EV charging control

You will learn how individual modules cooperate and how CIB forms a complete system.

If you prefer to go straight to the catalog:

Online B2B catalog – CIB modules are organized as follows

CFox – CIB bus modules

  • CFox – CIB system modules

  • CFox – DIN-rail modules

  • CFox – embedded modules

  • CFox – outdoor modules (IP54 / IP65)

  • CFox – indoor modules

CFox – CIB wall controllers and sensors

Each of these categories leads directly to the B2B catalog, where you will find specific types, variants, and technical parameters.
