The IOC4T input /output card acts as a signal interface for the series MPC4 machinery protection card. It is installed in the rear of a VM600 rack and connects directly to the rack backplane via two connectors.

Each IOC4T card is associated with a corresponding MPC4 card and is mounted directly behind it in the VM600 rack (ABE04x or ABE056). The IOC4T operates in slave mode and communicates with the MPC4, through connector P2, using an Industry Pack (IP) interface.

The front panel of the IOC4T (rear of the VM600 rack) contains terminal strip connectors for wiring to the transmission cables coming from measurement chains (sensors and /or signal conditioners). The screw-terminal connectors are also used to input all signals from and output all signals to any external control system.
