CMF5U

Controller with display

 

CMF5U is a pre-programmed, configurable controller. It has 5 inputs/
outputs and can be configured to control temperature, CO

2

, humidity 

or pressure. All configuration and normal handling is done using the 
display and the knob on the front. From revision R18, it is possible to 
connect an external PT1000 setpoint device.

Installation

CMF5U must be mounted in a DIN-standard casing (minimum 7 
modules) or in a cabinet, either on a DIN-rail or, using the two screw-
pockets provided, by being screwed to any suitable flat surface in the 
cabinet. The controller can also be mounted in a cabinet door or other 
control panel, using a suitable front-mounting kit (CMF-KIT).
The controller must be connected to a 24 V AC safety insulating 
transformer providing mains insulation.

Follow table 1 below for connection. 

Table 1. I/O connection terminals. Terminals 2, 20 and 50 are internally con-
nected.

Digital inputs DI and UI are only intended to be used with a 

potential-free contact or switch.

 

If the CMF5U and active sensors and 

actuators connected to it share transformer, it is essential that the 
same transformer-pole is used as reference for all the equipment. 
Failure to do so will prevent the equipment from functioning as 
intended and may also lead to damages.

For best protection against disturbances, a shielded twisted-pair cable 
should be used for wiring the sensors. Ground the shield at one end.
The protection provided by the equipment may be impaired by im

-

proper use.
