PTC Thermistor Card MCB 112
The MCB 112 option makes it possible to monitor the
temperature of an electrical motor through a galvanically-
isolated PTC thermistor input. It is a B option for adjustable
frequency drives with STO.
For different application possibilities, see
chapter 4 Application Examples.
X44/1 and X44/2 are the thermistor inputs. X44/12 enables
STO of the adjustable frequency drive (T37), if the
thermistor values make it necessary, and X44/10 informs
the adjustable frequency drive that a request for STO came
from the MCB 112 to ensure suitable alarm handling. One
of the digital input parameters (or a digital input of a
mounted option) must be set to [80] PTC Card 1 to use the
information from X44/10. Configure 5-19 Terminal 37 Safe
Stop to the desired STO functionality (default is safe stop
alarm).

The MCB 112 has been certified for ATEX, which means
that the adjustable frequency drive with the MCB 112 can
be used with motors in potentially explosive atmospheres.
