Tag: VM600 IOC4T

The lOC4T input /output card acts as a signalinterface for the yM600 series MPC4 machineryprotection card, from Meggitt’s Vibro-Meter@product line.lt is installed in the rear ofa yM600rack and connects directly to the rack backplanevia two connectors.
EachlOC4T card is associated with acoresponding MPC4 card and is mounteddirectly behind it in the VM600 rack (ABE04x orABE056).The l0C4T operates in slave mode andcommunicates with the MPC4, throughconnector P2, using an Industry Pack (IP]interface.
The front panel of the lOC4T (rear of the VM600rack)contains terminal strip connectors for wiringto the transmission cables coming frommeasurement chains(sensors and /or signalconditioners).The screw-terminal connectors arealso used to input all signals from and output allsignals to any external control system.
The lOC4T card protects all inputs and outputsagainst electromagnetic interference (EMl) andsignal surges and also meets electromagneticcompatibility (EMC] standards.
The lOC4T connects the raw dynamic (vibration)and speed signals from the sensors to the MPC4These signals,once processed, are passed backto the lOC4T and made available on the terminalstrip on its front panel (rear of VM600]. For thedynamic signals, four on-board digital-to-analogconverters(DACs) provide calibrated signaloutputs in the range 0 to 10 Y.in addition, four on.

board voltage-to-curent converters allow thesignals to be provided as current outputs in therange 4 to 20 mA (jumper selectable).
The lOC4T contains four local relays that can beattributed to any specific alamm signals undersoftware control. For example, these may be usedto signal an MPC4 fault or a problem detected bya common alamm ($ensor OK, Alarm and Danger])in a typical application.
In addition,32 digital signals representing alarmsare passed to the rack backplane and may beused by optional RLCl6 relay cards and /or lRC4intelligent relay cards mounted in the rack(jumper selectable).
Applications information
When used as a card pair with an MPC4machinery protection card, the lOC4T is highlysuitable for machinery monitoring and protectionin a wide range of industrial applications.
For further information on the use of MPC4/IOC4Tcard pairs in general, refer to the
VM600 machinery protection system (MPS)hardware manual and the VM600 MPSx softwaremanuals. For information on the use ofMPC4/l0C4T card pairs in functional safetycontexts,refer to the refer to the yM600functional safety manual.
