Discrete Signal Interface (DSI) inputs

Description

IOC4T Card

The IOC4T Input/Output card is the signal interface for Meggitt’s VM600 series MPC4 machine protection card.

It is mounted on the rear of the VM600 rack and connects directly to the rack backplane via two connectors.

Each IOC4T card is associated with the corresponding MPC4 card and is mounted directly to the rear of the VM600 rack (ABE04x or ABE056).

The IOC4T operates in slave mode and communicates with the MPC4 through connector P2 using the Industrial Packet (IP) interface.

The front panel of the IOC4T (rear of the VM600 frame) contains terminal strip connectors

for connecting the transmission cables from the measurement chain (sensors and/or signal conditioners).

The threaded terminal connectors are also used to input all signals from any

external control system and output all signals to any external control system.

The IOC4T card protects all inputs and outputs from electromagnetic interference (EMI)

and signal surges and complies with electromagnetic compatibility (EMC) standards.

The IOC4T connects raw dynamic (vibration) and velocity signals from sensors to the MPC4.

These signals are processed and passed back to the IOC4T and made available on its front panel (rear of the VM600) terminal strip.

For dynamic signals, four on-board digital-to-analog converters (DACs) provide calibrated signal outputs in the 0 to 10 V range.

In addition, four on-board voltage-to-current converters provide current output signals in the 4 to 20 mA range (jumper optional).

The IOC4T contains four local relays that can be used for any specific alarm signal under software control.

Key Features and Benefits

– From the Vibro-Meter® product family

– Signal interface card with 4 dynamic signal inputs and 2 tachometer (speed) inputs for MPC4 mechanical protection cards

– Screw terminal connectors for all input/output connections (48 terminals)

– Includes 4 relays that can be used for alarm signaling under software control

– 32 fully programmable open collector outputs (jumpers optional) for connection 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

– Real-time plug-in cards (hot-swappable)

– Available in “standard” and “circuit independent” versions

Applications

– Mechanical protection and/or basic condition monitoring​

Features

System isolation

The VM600Mk2 uses a single type of card (MPC4Mk2) for monitoring and condition monitoring.

However, these functions are tightly segregated to ensure API 670 compliance and reduce costs.

A separate (optional) XMV16 condition monitoring card is available for applications with a large number of channels.

High channel density

The standalone VM600Mk2 protection card has 4 input channels, but each VM600 can be expanded

to a maximum of 48 input channels Mk2 racks, allowing vibration protection to be extended to the most demanding rotating machinery.

Advanced Monitoring

The stand-alone VM600Mk2 condition monitoring card offers 16 dynamic channels and 4 tachometer channels,

which can all be independently configured to provide unrivaled accuracy and reliability.

Description of the RLC16 Relay Card

The RLC16 relay card is designed for use in dcs-sis.com Meggitt Sensing Systems’ VM600 Series Vibrometer® product line for mechanical protection systems as well as condition and performance monitoring systems.

It is an optional card for use when the four relays on the IOC4T I/O card are insufficient for the application and additional relays are required.

The RLC16 is mounted on the rear of the VM600 (ABE04x) rack and connects directly to the rack backplane via a connector.

The RLC16 contains 16 relays with changeover contacts. Each relay is associated with 3 terminals on the screw terminal strip at the rear of the VM600 rack.

The relays are controlled by software-controlled open collector actuators.Jumpers on the RLC16 card allow selection of either Normal Energized (NE) or Normal De-energized (NDE) relays.
