EAU01 Emerson AC Power Distribution Monitoring Unit for DC Power Systems EMU10 EMU10LC Companion Module

Product Overview: Emerson EAU01 

Parameter Specification
Manufacturer Emerson 
Order Number EAU01 
Product Type Monitoring & control module — not a rectifier/charging module, not a battery, not a main monitor
Core Function Collects AC input signals and drives AC input contactors, enabling automatic changeover between two independent AC supplies

Application & Fault Scenarios

Typical Uses: Installed in substation and telecom DC power screens to monitor two independent AC feeds, drive the input contactors for automatic changeover, and report status to the EMU10/EMU10LC main monitor. Standard like-for-like swap when an ageing unit fails or when a cabinet is refurbished.
Common Field Issues:
  • ALARM LED on / no communication with the main monitor → check RS485/CAN wiring, termination and address settings, and confirm the firmware pairing with the EMU10/EMU10LC.
  • Contactor will not pull in or hold → verify the 220 Vdc pull-in and 12 Vdc hold supply, contactor coil condition and the interlock logic; also check the configured switching threshold and time.
  • Wrong or zero current reading → current inputs must come through correctly rated front-end CTs with correct polarity and burden.
  • Voltage reading abnormal with no neutral → confirm the wiring mode; the unit can measure without a neutral, but phase/line wiring must match the configuration.

FAQ

Q1: What is the Emerson EAU01?
A: An AC power distribution monitoring unit for DC power systems — it acquires two independent AC feeds (6 voltage / 3 current channels plus 6 digital inputs), drives two input contactors for automatic changeover, and reports to an EMU10/EMU10LC main monitor over RS485 or CAN.
Q2: Can it work alone?
A: No. It is a companion module designed to operate with a main monitoring unit such as EMU10 or EMU10LC, or as a standalone AC monitor with its own display/head in some configurations.
Q3: Is EAU01 the same as EDU01 or EGU01?
A: No — EAU01 handles AC distribution, EDU01 handles DC distribution, and EGU01 handles generator monitoring. Check your nameplate before ordering.
