VM-600 IOC4T  VM600 IOC4T input/output card 

IOC4T card
The lOC4T input /output card acts as a signalinterface for the VM600 series MPC4 machineryprotection card, from Meggitt’s Vibro-Metereproduct line.lt is installed in the rear ofa yM600rack and connects directly to the rack backplanevia two connectors.
Each lOC4T card is associated with a
coresponding MPC4 card and is mounteddirectly behind it in the wM600 rack (ABE04x orABE056).The lOC4T operates in slave mode andcommunicates with the MPC4, throughconnector P2, using an Industry Pack (lP)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 MPC4.These 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 v.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 alarm (Sensor 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).
