Different versions of the MPC4 card

There are different versions of the MPC4 card, including “Standard”, “Circuit Independent” and “Secure”

(SIL) versions.

In addition, some versions have a conformal coating applied to the card’s circuitry to provide additional

environmental protection against chemicals, dust, moisture and temperature extremes.

Both the “Standard” version and the “Safety” (SIL) version of the MPC4 card are certified to

IEC 61508 and ISO 13849 for use in functional safety environments such as SIL 1 according to IEC 61508 and ISO 13849-1 for PL c.

The “standard” MPC4 card is the original version and supports all functions and processing modes.

The “standard” MPC4 is suitable for safety systems using the VM600 rack. 

There are three versions of the MPC4 card: the “standard” version, the “circuit independent” version,

and the “safe” (SIL) version, all of which use the appropriate IOC4T input /output cards as card pairs.
