The "AC-RC" designation indicates the specific power and input requirements of the device. This unit is designed to operate on AC voltage (typically 100–240 V AC), making it suitable for standard industrial power supplies without the need for external transformers or DC conversion modules.
From left to right on the top and bottom rows:
| Terminal | Signal | Exclusive Manual Note | | :--- | :--- | :--- | | Top Row (Power & Inputs) | | | | L / N | 24V AC/DC Supply | Use a Class 2 power supply. Polarity insensitive for DC. | | I1 – I8 | Digital Inputs (24V DC) | I4 can be high-speed counter (5 kHz). I7 & I8 can be analog (0-10V). | | Bottom Row (Outputs) | | | | Q1 – Q8 | Relay Outputs (Common C1/C2) | Qt1 & Qt2 share common C1. Qt3-Qt8 share common C2. |
Exclusive Warning: Never mix AC and DC loads on the same output common. If using C1 for AC contactors, all Q1-Q2 outputs on that common must switch AC.
Look for the official Moeller/Eaton EASY 619 ACRC manual on vendor pages, Eaton support, or authorized documentation repositories. The manual filename typically includes the product code and “manual” or “installation and programming guide.” Always verify the version/date to match your hardware variant.
