3.2.4 Galvanic Isolation
The VLT® Extended Relay Card MCB 113 can be connected to an 24 V external supply on X58/ to ensure galvanic isolation between the
drive and the option card. If galvanic isolation is not needed, the option card can be supplied through internal 24 V from the drive. The
internal 24 V supply is available on X58 if
parameter 14-80 Option Supplied by External 24VDC
is set to
[0] No
.
The relays support a combination of 24 V and 250 V signals as long as there is an unused relay in between.
