Description

Processed dynamic (vibration) and velocity signals are available as analog outputs at the rear of the rack

(on the front panel of the IOC4T).

Voltage signals (0 to 10 V) and current signals (4 to 20 mA) are available.

The MPC4 performs self-tests and diagnostic procedures at power-up.

In addition, the card’s built-in “OK system” continuously monitors the signal level provided

by the measurement chain (sensors and/or signal conditioners) and indicates any problems

caused by broken transmission lines, faulty sensors or signal conditioners.

An LED on the front panel of the MPC4 indicates whether a processing or hardware error has occurred.

A further six LEDs, one for each input channel, indicate whether the OK system has detected

a fault and whether an alarm has occurred on the channel.

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.
