MCB 108 Safe PLC Interface (FC 302 only)
A cost-effective method of ensuring safety, the Safe PLC interface enables the connection of a dual-wire safety link between a Safe PLC and a single pole 24 V DC input on the drive. The Safe PLC Interface allows the Safe PLC to interrupt operation on the plus or minus link without interfering with the sense signal of the Safe PLC.
MCB 112 Thermistor Input (FC 302 only)
The MCB 112 option makes it possible to monitor the temperature of an electrical motor through a PTC thermistor input. It is a B-option for VLT® AutomationDrive FC 302 with Safe Stop.The MCB 112 has been certified for ATEX which means that the VLT® AutomationDrive FC 302 together with the MCB 112 can now be used with motors in potentially explosive atmospheres.
