200-510-SSS-1Hh MPC4 Machinery Protection Card

The 'standard' 200-510-SSS-1Hh 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.

The processed dynamic signals and speed signals are available at the rear of the rack as analog output signals. Voltage-based (0-10 V) and current-based (4-20 mA) signals are provided. The MPC 4 performs a self-test and diagnostic routine on power-up. In addition, the card's built-in "OK System" continuously monitors the level of signals provided by the sensors and indicates any problem due to a broken transmission line, faulty transducer or conditioner. An LED indicator on the MPC 4 front panel indicates whether a processing or hardware error has occurred. Six additional LEDs (one per channel) indicate whether the OK System has detected a fault and whether an alarm has occurred on the channel.
