This system relay card delivers dependable alarm and trip outputs for critical asset protection. It translates measurement data into actionable relay contact signals for your safety systems. We engineered the Emerson A6500-RC specifically for the AMS 6500 machinery protection platform. This card provides the final output stage for vibration and process alarms. It ensures that your control systems receive immediate alert signals when thresholds exceed. Therefore, your personnel can respond quickly to developing machinery faults.
Mechanical Configuration and Physical Attributes
The Emerson A6500-RC features a standard Eurocard form factor for rack integration. Its dimensions measure 233.4 mm in height, 20.3 mm in width, and 160.0 mm in depth. The card weighs approximately 0.45 kilograms for simple installation procedures. This unit occupies a single slot within the AMS 6500 instrument rack. It connects to the measurement cards via the internal backplane communication bus. The card presents its relay outputs on the front-panel terminal blocks.
Relay Outputs and Switching Capabilities
This relay card offers eight independent relay outputs for flexible alarm configuration. Each relay provides form C contacts with normally open and normally closed positions. The Emerson A6500-RC handles switching loads up to 2 A at 250 VAC. It supports both latching and non-latching operating modes for diverse applications. The card includes individual LED indicators for each relay channel status. It also incorporates a watchdog relay to monitor the controller health. Consequently, this ensures fail-safe operation for your critical protection circuits.
