· Link between control and power levels
· For separating potentials
Some electronic devices, e.g. frequency inverters, microprocessor
systems etc. offer the possibility to signalize faults and operating conditions
via one or more logic outputs. However, the problem is the minimum
loading of these outputs and the voltage of e.g. DC 15 V, which is not
normal in the control technique.

Function
A1 11 21
The MK 3044 is a interface relay with an additional control input. The
supply voltage DC 24 V will be applied to A1/A2. The relay switches, when
the input B1/B2 is connected to a voltage between AC/DC10...30 V.
