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.
