Eaton EMR-3000-2A1DA1 Motor Relay - Profibus-DP over Fiber Optic ST
Part Number: EMR-3000-2A1DA1
Quick Summary
EMR-3000-2A1DA1 motor relay from Eaton provides robust motor control for industrial drives in automation panels and distributed control systems. It is designed to simplify complex wiring while delivering reliable I/O, timing, and fieldbus communication in harsh environments. Engineers often struggle to integrate precise synchronization and safe, fault-tolerant signaling across multiple devices, which can lead to downtime and maintenance costs. This device offers IRIG-B timing support and Profibus-DP capability over fiber optic ST, enabling accurate time stamping and noise-immune communication. Compliance details are defined by the manufacturer, but the Eaton motor-relay family commonly supports CE marking and IP-rated configurations at the order level, with SIL considerations available per application. In practice, it enhances network compatibility and reduces integration risk in modern automation systems.
