Danfoss offers a wide range of options and accessories.
3.1.1 General Purpose Input Output
Module MCB 101
MCB 101 is used for extending the number of digital and
analogue inputs and outputs.
MCB 101 must be fitted into slot B in the frequency
converter.

Galvanic isolation in the MCB 101
Digital/analog inputs are galvanically isolated from other
inputs/outputs on the MCB 101 and in the control card of
the frequency converter. Digital/analog outputs in the MCB
101 are galvanically isolated from other inputs/outputs on
the MCB 101, but not from those on the control card.
If the digital inputs 7, 8 or 9 are to be switched using the
internal 24 V power supply (terminal 9), the connection
between terminals 1 and 5, which is shown in
Illustration 3.2 has to be established.
