Description of the RLC16 Relay Card

The RLC16 relay card is designed for use in 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.

SPECIFICATIONS

OVERVIEW

Housing: Painted galvanized steel sheet

Color: Off-white (RAL 9002)

Power supply: Integrated RPS1U power supply for VM600Mk2/VM600

The integrated RPS1U power supply provides +5 VDC and ±12 VDC for the VM600Mk2/VM600 and all installed modules (cards).

See also AC Input Power on page 3 and DC Input Power on page 3.

Power Input: The power input has an AC or DC connector (with RFI filter) and an on/off switch.

See Ordering Information on page 6 for information on the main power cord (power strip).

Backplane: Proprietary VM600Mk2/VM600 rack bus (open collector (OC) bus) for data/signal sharing between modules (cards)

Rack Slots (module (card) locations):

Front of rack:

– 1 × slot – module (card) position 01 – for handling modules (cards) such as MPC4Mk2. XMx16. MPC4. or AMC8.

Rear of rack:

– 1 × Slot – Module (Card) Position 01 – For associated input/output modules (cards) such as IOC4Mk2. XIO16T, IOC4T or IOC8T.

– 1 × slot – module (card) position 00 – for the relevant relay module (card), e.g. RLC16Mk2 or RLC16.

​Both power supplies support a wide input voltage range.

The rack has an integrated backplane that provides electrical interconnection between the integrated

power supply (RPS1U) and the installed VM600Mk2/VM600 modules (cards).

The rack also has a power check relay on the rear of the rack to indicate if the integrated power supply is

functioning properly.

The VM600Mk2/VM600 Processing Module (Card) is mounted at the front of the rack and the

associated Input/Output Module (Card) is mounted at the rear of the rack.

The input/output modules (cards) provide connectors for connecting sensors/measurement

chains and for sharing various signals with external systems such as DCS or PLC.

In general, the VM600Mk2/VM600 ABE056 Ultra Slim Racks are factory-configured before shipment and

are therefore ready for use.

Optionally, each module (card) can be reconfigured to meet the needs of a specific machinery monitoring

application.

Each module (card) can be reconfigured to meet the needs of a specific machinery

monitoring application using the appropriate software package from Meggitt Vibro-Meter: VibroSight®

or VM600 MPSx.

Applications

– VM600Mk2/VM600 Mechanical Protection and/or Condition Monitoring Systems

VM600Mk2/VM600 Mechanical Protection and/or Condition Monitoring Systems

The VM600Mk2/VM600 ABE056 slimline rack is used to house the hardware for

the VM600Mk2/VM600 series of machine protection and/or condition monitoring systems in the

Vibrometer® product line.

The VM600Mk2/VM600 ABE056 slimline rack has a standard height of 1U and provides mounting

space (rack slots) for a single wide VM600Mk2/VM600 processing module (card pair) and a relay module

(card).

This rack is particularly suitable for industrial environments where the equipment must be permanently

installed in a 19-inch cabinet or panel.

Different versions of the integrated RPS1U power supply can power the VM600Mk2/VM600

ABE056 slimline racks from an external AC or DC power supply.

Both power supplies support a wide input voltage range.

The rack has an integrated backplane that provides electrical interconnection between the integrated

power supply (RPS1U) and the installed VM600Mk2/VM600 modules (cards).

The rack also has a power check relay on the rear of the rack to indicate if the integrated power supply is

functioning properly.

The VM600Mk2/VM600 Processing Module (Card) is mounted at the front of the rack and the

associated Input/Output Module (Card) is mounted at the rear of the rack.

The source and type of each channel is selectable during card configuration.

Cold Junction Compensation (CJC) sensor processing is used for the thermocouple temperature

channel and can be used for two of the eight channels, also selectable during card configuration.

All inputs are conditioned and compared to user-configurable alarms that are defined through Meggitt’s VM600 MPSx software.

A pair of AMC8/IOC8T cards is configured (i.e. operated independently) via the RS-232 port on the front panel of the relevant AMC8 card.

The AMC8 card also provides access to the CPUx card (ABE04x only) in slot 0 of the VM600 rack via the VME bus.

These interfaces allow the operator to configure the VM600 card, access measurements,

view detailed board status, upload firmware updates, and more.

The AMC8 card can drive the four local relays on the IOC8T card, as well as any of the 16 relays

on the RLC16 card using the VM600 rack’s raw bus and/or open collector (OC) bus.

These cards also provide analog signal outputs based on current (0 to 25 mA). Voltage outputs are also supported.

Description

AMC8 Card

The AMC8 is an analog monitoring card designed for use in the VM600 rack-mounted system

in the Meggitt Vibrometer® product family for machinery monitoring and protection applications.

This versatile card is capable of measuring and monitoring up to eight analog signal inputs simultaneously.

The AMC8 card is available in two versions: a “standard” version and a “circuit independent” version,

both of which are available as card pairs using the corresponding IOC8T input/output card.

The AMC8 card is mounted on the front of the VM600 rack (ABE04x or ABE056) and the IOC8T I/O card is mounted on the rear.

Both cards connect directly to the rack backplane via two connectors.

A pair of AMC8/IOC8T cards provides eight channels of temperature monitoring that accept resistance

temperature detector (RTD) and thermocouple (TC) temperature inputs as well as process inputs.

Control signals

– Alarm Reset (AR): A closed contact between the DSI AR and DSI RET inputs resets (clears) the

MPC4/IOC4T card’s alarm to lockout.

NOTE: The alarm reset input (DSI AR) is edge sensitive and requires a high to low transition to activate the

reset.

– Danger Bypass (DB) : A closed contact between the DSI DB and DSI RET inputs inhibits (bypasses) the

Danger Relay output.

– Trip Multiplier (TM): The closed contact between the DSI TM and DSI RET inputs multiplies

the alarm level by a scaling factor (configurable via software) for adaptive monitoring.

Principle of operation: Detects open or closed circuits on the inputs Alarm outputs

Alarm relays: 4 per IOC4T card.

The MPC4 card can drive the four local relays on the IOC4T card, as well as the relays on 

the RLC16 relay card and/or the IRC4 Smart Relay card via the Raw bus or open collector (OC) bus in the

VM600 chassis.

See Relay Characteristics on page 4 for IOC4T card relay functions.
