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 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).
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.
