AMC8 Vibration 200-550-005-112 Analog Monitoring Card Pair

Description:

AMC8 card

The AMC8 is an analog monitoring card designed for use with the VM600 rack-based systems for machinery monitoring and protection applications, from Meggitt’s Vibro-Meter® product line. 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 “separate circuits” version, both of which function as a card pair using an appropriate IOC8T input/output card. 

The AMC8 card is installed in the front of a VM600 rack (ABE04x or ABE056) and the IOC8T input/ output card is installed in the rear. Both cards connect directly to the rack’s backplane via two connectors.

An AMC8/IOC8T card pair provides eight channels of temperature monitoring, accepting both resistance temperature detector (RTD) and thermocouple (TC) temperature inputs, as well as process inputs. The source and type for each channel is selected when the card is configured.

Cold-junction compensation (CJC) sensor processing, used for the thermocouple temperature channels, is available on two of the eight channels and is also selected when the card is configured. 

All inputs are conditioned and compared against user-configurable alarms, which are defined using the VM600 MPSx software from Meggitt.

An AMC8/IOC8T card pair is configured using the RS-232 port located on the front panel of the associated AMC8 card (that is, standalone operation). 

The AMC8 card can also be accessed via the VME bus by a CPUx card present in slot 0 of the VM600 rack (ABE04x only). These interfaces allow operators to configure VM600 cards, access measurement results, view detailed board status, upload firmware updates and much more.

The AMC8 card can drive four local relays on the IOC8T card, as well as any of the 16 relays on an RLC16 card using the VM600 rack’s Raw bus and/ or Open Collector (OC) bus.

The cards also provide current-based (0 to 25 mA) analog signal outputs. Optionally, voltage-based output is also supported. Applications information

The AMC8/IOC8T card pair is highly suitable for machinery monitoring and protection in a wide range of industrial applications.
