IRC4 Vibration 601-001-001-003 Intelligent Relay Card

Description:

The IRC4 intelligent relay card is designed for use in the VM600 series of machinery protection systems and condition and performance monitoring systems, from Meggitt Sensing Systems’ Vibro-Meter® product line. It is an optional card, for use when complex combinations of internal discrete outputs from MPC4 and/or AMC8 cards are required.

The IRC4 is a jumperless card driven by a modern 16-bit microcontroller. This product can process complex equations with up to 86 discrete inputs coming from all the MPC4 and AMC8 cards installed in a VM600 rack. Its high level of configuration makes it ideal to manage 2oo3 (two-out-of-three) voting.

The IRC4 is installed in the rear of a VM600 (ABE04x) rack and connects directly to the rack backplane via a single connector.

The IRC4 contains eight relays with change-over contacts. Each relay is associated with three terminals on a screw terminal strip accessible at the rear of the rack.

IRC4 cards are fully software configurable using“IRC4 Configurator”, a dedicated Windows® program from Meggitt Sensing Systems with a graphical user interface. No jumpers are needed, since every parameter of an IRC4 is set using this software.

The IRC4 Configurator software uses the MPS file from the rack environment and a Microsoft® Excel® file that describes the required logic equations (the“VM signals list”) as inputs.
