ABB – OREL‑01‑KIT – 3AUA0000002040 Relay Output Extension Module

The ABB OREL‑01‑KIT (part number 3AUA0000002040) is a dedicated relay output expansion module designed for ACS550 and ACH550 variable frequency drives. It adds three Form‑C relay outputs (RO4, RO5, RO6)—each capable of handling both 2 A RMS continuous or 6 A DC/AC resistive loads—offering enhanced output functionality without needing the drive’s internal relay.
