See Additional specifications – for “standard” and “separate circuits” MPC4 cards only on page 9.

The “standard” and “separate circuits” versions of the MPC4 card support narrow-band tracking but the 

“safety” version of the card (MPC4SIL) does not.

Alarm processing and combination

Level detectors

• Vibration systems : Over-level switching (A+, D+) and under-level switching (A−, D−)

• Accelerometer systems : Over-level switching (A+, D+)

• Speed channel : 2 Alert levels (A−, A+)

Alarm scanning interval : 100 ms max.

Alarm level value : User-programmable within range

Hysteresis

Latching

: User-programmable within range

: User-programmable within range

Alarm delay time : User-programmable within range

Alarm outputs : Individual alarms and common alarms (open-collector transistor)

Adaptive monitoring : Adaptive monitoring uses a control parameter (such as speed) to 

multiply the configured alarm limits by multiple coefficients 

configured for different ranges of the control parameter.

Trip multiplier uses the DSI TM control signal to multiply the 

configured alarm limits by a single configurable coefficient.

Adaptation criteria

(for adaptive monitoring)

: Speed or digital input

Logical combinations : AND, OR and majority voting logic

Number of logical combinations : 8 basic functions and 4 advanced functions

SPECIFICATIONS – COMMON TO ALL MPC4 CARDS (continued)

Communications

VME bus : A24/D16 slave mode

RS-232 port : Configuration and communications port, proprietary protocol 

(see Connectors on page 8)

MPC4 to IOC4T bus : Similar to industry pack (IP)

Note: The VME bus provides access to the MPC4/IOC4T card pair via a CPUx card, in order to support Ethernet 

and/or fieldbus communications. The RS-232 port (front-panel serial interface) provides access to the MPC4/

IOC4T card pair for standalone operation, that is, when a CPUx card is not installed in the VM600 rack. An 

MPC4/IOC4T card pair is software configurable via VME or RS-232 (see Configuration on page 7).

Note: The “standard” and “separate circuits” versions of the MPC4 card include a VME bus but the “safety” 

version of the card (MPC4SIL) does not. Therefore, the “standard” and “separate circuits” versions of the MPC4 

card are software configurable via RS-232 or VME but the MPC4SIL card is software configurable via RS-232 

only.

Configuration

MPC4/IOC4T card pair : Software configurable via an RS-232 or Ethernet connection, using 

a computer running the VM600 MPSx software.

Hardware configurable using jumpers on the MPC4/IOC4T card 

pair.

Note: Configuration via an Ethernet connection requires a CPUx card acting as a rack controller in the VM600 

rack.

Status indicators (LEDs)

DIAG/STATUS : One multicolour (green/yellow/red) LED used to indicate the status 

of the MPC4/IOC4T card pair, such as normal operation, 

configuration status or internal hardware or firmware failures

RAW OUT 1 to 4 : Four multicolour (green/yellow/red) LED used to indicate the status 

of the individual dynamic channels

TACHO OUT 1 to 2 : Two multicolour (green/yellow) LED used to indicate the status of 

the individual tachometer (speed) channels

Power supply to card (input)

Power source : VM600 rack power supply

Supply voltages : +5 VDC and ±12 VDC

Consumption from +5 VDC supply : 12.5 W typ., plus an additional 1 W per sensor used

Consumption from ±12 VDC supply : 2.5 W max.

Power supply to sensors (output)

Voltage power supply : +27.2 V ±5% in the range 0 to 25 mA.

−27.2 V ±5% in the range 0 to 25 mA.

+15.0 V ±5% in the range 0 to 25 mA.
