MPC4 200-510-071-113 Machinery Protection Card

The 'standard' 200-510-071-113 MPC4 card is the original version, intended for safety systems using a VM600 rack with a limited range of cards, that is, 'standard' MPC4 / IOC4T card pairs and RLC16 relay cards. It has a VME-compatible slave interface and is fully software configurable via RS-232 (on the front panel of the card) or VME.

Segregation of MPS and CMS：

    The VM600 rack, machinery protection cards, condition monitoring cards and associated software are designed for compliance with the machinery protection system (MPS) and condition monitoring system (CMS) "segregation" requirements of the API 670 standard, which ensures that the functionality of the MPS does not depend on and is not compromised in any way by the operation of the CMS.

    So although machinery protection cards and condition monitoring cards can easily share sensor signals from measurement chains, MPC4/IOC4T card pairs do not share any communication buses with XMx16/XIO16T condition monitoring card pairs in a VM600 rack, and MPC4/IOC4T card pairs are configured and operated using the VM600 MPSx software (while XMx16/ XIO16T card pairs are configured and operated using the VibroSight® software).

Applications information：

The MPC4 cards are highly suitable for machinery protection in a wide range of industrial applications. For further information on the use of MPC4 cards, refer to the VM600 Functional Safety Manual MAVM600-FS/E. For specific applications, contact your nearest Meggitt Sensing Systems representative.
