Take Control with Confidence: Introducing the New CMA Coupling Module Family
ComatReleco expands its portfolio with the new CMA coupling module family with manual control – a compact and intelligent solution designed for safer intervention, clearer system visibility, and more reliable operation in building automation and industrial applications. The new range combines practical manual control with seamless integration into automated systems, enabling fast and safe intervention whenever direct action is required.
In today’s installations, flexibility in the field is no longer a convenience – it is a necessity. During commissioning, service, maintenance, or troubleshooting, it must be possible to operate selected functions manually, even when the control system is inactive or temporarily unavailable. The CMA family has been designed precisely for these moments. It enables safe switching between automatic and manual operation, while a dedicated feedback contact keeps the higher-level controller informed of the current operating mode at all times.
With the CMA range, ComatReleco offers a solution that is as practical as it is elegant. The modules provide clear mode selection, reliable status feedback, and intuitive operation in a compact 17.5 mm housing for DIN rail mounting. This makes them ideal for modern control cabinets where space, clarity, and efficiency matter.
The new family includes both digital and analogue variants, allowing users to choose the right module for a wide variety of signal types and applications. The range covers:
- CMA-D111/UC24V – 1 digital channel, 1 changeover contact
- CMA-D211/UC24V – 2 digital channels, 2 changeover contacts
- CMA-U111/UC24V – analogue 0…10 V
- CMA-I111/UC24V – analogue 0…20 mA
This broad family concept makes CMA a versatile choice for applications involving actuators, valves, pumps, ventilation systems, heating coils, and other field devices that require dependable manual override or analogue signal handling. The analogue versions additionally provide a setpoint-dependent LED indication, offering an intuitive visual reference of the operating state.
The benefits are clear: greater operational reliability, faster commissioning, simplified troubleshooting, and reliable emergency operation when the control system is not available. Rather than adding complexity, CMA helps reduce uncertainty in the field and supports smooth, transparent system operation when it matters most.
For panel builders and integrators, the new modules also support straightforward installation and expansion. Accessories such as 2-pole, 4-pole, and 8-pole potential bridge bars are available to simplify wiring and make cabinet integration even more efficient.
With CMA, ComatReleco delivers more than a coupling module. It delivers a smarter way to bridge automation and manual control – compact, intuitive, and built for real-world demands.
