Meggitt Vibro MeterVM600 IOC4T input output card

DESCRIPTION

IOC4T card The IOC4T input /output card acts as a signal interface for the VM600 series MPC4 machinery protection card, from Meggitt’s Vibro-Meter® product line. It is installed in the rear of a VM600 rack and connects directly to the rack backplane via two connectors. Each IOC4T card is associated with a corresponding MPC4 card and is mounted directly behind it in the VM600 rack (ABE04x or ABE056). The IOC4T operates in slave mode and communicates with the MPC4, through connector P2, using an Industry Pack (IP) interface. The front panel of the IOC4T (rear of the VM600 rack) contains terminal strip connectors for wiring to the transmission cables coming from measurement chains (sensors and /or signal conditioners). The screw-terminal connectors are also used to input all signals from and output all signals to any external control system. The IOC4T card protects all inputs and outputs against electromagnetic interference (EMI) and signal surges and also meets electromagnetic compatibility (EMC) standards. The IOC4T connects the raw dynamic (vibration) and speed signals from the sensors to the MPC4. These signals, once processed, are passed back to the IOC4T and made available on the terminal strip on its front panel (rear of VM600). For the dynamic signals, four on-board digital-to-analog converters (DACs) provide calibrated signal outputs in the range 0 to 10 V. In addition, four on

board voltage-to-current converters allow the signals to be provided as current outputs in the range 4 to 20 mA (jumper selectable). The IOC4T contains four local relays that can be attributed to any specific alarm signals under software control. For example, these may be used to signal an MPC4 fault or a problem detected by a common alarm (Sensor OK, Alarm and Danger) in a typical application. In addition, 32 digital signals representing alarms are passed to the rack backplane and may be used by optional RLC16 relay cards and / or IRC4 intelligent relay cards mounted in the rack (jumper selectable). Applications information When used as a card pair with an MPC4 machinery protection card, the IOC4T is highly suitable for machinery monitoring and protection in a wide range of industrial applications. For further information on the use of MPC4/IOC4T card pairs in general, refer to the VM600 machinery protection system (MPS) hardware manual and the VM600 MPSx software manuals. For information on the use of MPC4/IOC4T card pairs in functional safety contexts, refer to the refer to the VM600 functional safety manual. For specific applications, contact your local Meggitt representative.
