Product Description
Overview
The A6824R from Emerson is a high-performance ModBus and rack interface module designed for the IMR6500 series machinery protection systems. Its 4TE wide, 1-slot plug-in format optimizes cabinet space, reducing the footprint by half compared to traditional 6U cards. This module supports optional redundancy, hot-swappable installation, and comprehensive self-monitoring to ensure reliable system performance in critical applications.
Key Features

FAQ
Q: Can this module be used in IMR6000 series racks?
A: No, the A6824R is designed specifically for the IMR6500 series. A separate 6TE, non-redundant version exists for IMR6000.
Q: Does the module require powering down the rack for installation?
A: No, it is fully hot-swappable.
Q: How is redundancy configured?
A: Redundancy can be enabled through the module configuration menu, providing automatic failover between primary and backup channels.
Q: What type of network interfaces are supported?
A: ModBus RTU over serial and ModBus Ethernet via RJ45 10Base-T.
