Identifying different versions of the MPC4 card

The different versions of the MPC4 card can be visually identified from their panels, as the

lower handle on the panel is different.

• For the standard and separate circuits versions of the MPC4 card, the label on the lower

handle of the panel displays the text “MPC4” against a blue background, as shown in

Figure4-1(a).

• For the safety (SIL) version of the MPC4 card, the label on the lower handle of the panel

displays the circular TÜVNord logo and text “MPC4” against an orange background, as

shown in Figure4-1(b).

The ordering number (PNR) for a MPC4 card is in given in the format 200-510-SSS-xHh.

In this PNR, x represents the version of the MPC4 card as follows:

• 1 indicates the standard version of the card.

• 2 indicates the separate circuits version of the card.

• 3 indicates the safety (SIL) version of the card.

NOTE: Refer to the MPC4 machinery protection card data sheet for further information.

In the VM600 MPSx software (version 2.6.x or later):

• MPC4 is used to refer to the standard and separate circuits versions of the MPC4 card.

• MPC4SIL is used to refer to safety version of the MPC4 card.

NOTE: Refer to the relevant manual for further information: VM600 MPS1 software

manual or VM600 MPS2 software manual

A block diagram of the MPC4. IOC4T, RLC16 and IRC4 cards is shown in Figure4-2. This

shows schematically the backplane, which physically divides the ABE04x rack into a front

card cage and a rear card cage.

The MPC4 (shown on the left of Figure4-2) is mounted in the front card cage. This card

effects the signal processing functions for the MPS. Its panel contains BNC connectors to

output the raw measurement signals (for example, corresponding to vibration or dynamic

pressure) and speed signals. An LED indicator (DIAG/STATUS) shows the hardware status

of the MPC4/ IOC4T card pair. Additional LED indicators are present to provide information

on the status of each individual channel (such as signal valid or the presence of alarms). The

panel also has a 9-pin D-sub connector for configuring an MPC4 card used in a stand-alone

rack, that is, one not containing a CPUM card.

Each MPC4 card is necessarily connected (via the backplane) to an IOC4T input/output card

mounted in the rear card cage. The IOC4T card’s panel (rear of rack) has screw terminals for

connecting the signal transmission lines coming from the transducers (for example, from

vibration and speed transducers). Other screw terminals are used to output raw signals as

well as processed signal values (0to10V or 4to20mA).

The IOC4T contains 4 local relays with outputs available on the screw terminal strip. In

applications needing more than the four relays provided by the IOC4T, an RLC16 relay card

or an IRC4 intelligent relay card can be installed in the rack.

The RLC16 card contains 16 relays and has a terminal strip with 48 screw terminals (3 strips

each having 16 terminals).

The IRC4 card contains 8 relays that can be combined as 4 DPDT or 8 SPDT and has a

terminal strip with 32 screw terminals (2 strips each having 16 terminals).
