|Description||Meggitt Vibro Meter IOC4T 200-560-000-014 VM600 input/output card|
KEY FEATURES AND BENEFITS
• From the Vibro-Meter® product line • Signal interface card with 4 dynamic signal inputs and 2 tachometer (speed) inputs, for the MPC4 machinery protection card
• Screw-terminal connectors (48 terminals) for all input/output connections
• Contains 4 relays which can be attributed to alarm signals, under software control
• 32 fully-programmable open-collector outputs (jumper selectable) to IRC4 and RLC16 relay cards
• Buffered “raw” sensor signals and analog output signals (voltage or current) for vibration channels
• EMI protection for all inputs and outputs • Live insertion and removal of cards (hot-swappable)
• Available in “standard” and “separate circuits” versions
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 onboard 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).
