CMA - Coupling module with manual control

In modern building automation and industrial systems, the ability to reliably operate individual functional groups manually is becoming increasingly important.

Both during commissioning and in the event of a
service call, it must be possible to check components
such as valves, pumps, ventilation units or heating
coils quickly and without active control. Manually
operable interface modules provide crucial support
here, as they enable specific system components to be
switched on or off, or analogue control variables to be
set manually.
These functions not only facilitate troubleshooting and
system calibration, but also ensure system operation if
a control system is temporarily unavailable.
ComatReleco offers a range of high-performance
digital and analogue interface modules specifically
developed for this application. They allow for safe
switching between automatic and manual operation
and, via a feedback contact, provide the master
controller with information on the current operating
mode at all times – an essential prerequisite for
transparent and trouble-free operation
