Moeller Easy512-ac-rc Programming Manual
The "AC-RC" designation in the model name specifies the electrical characteristics:
: Equipped with a real-time clock (R) and relay outputs (C). Key Technical Specs: Inputs: 8 Digital inputs. Outputs: 4 Relay outputs (up to 8A).
) : These are dry contact relay outputs. Connect the load (e.g., motor contactor, light) in series with the line voltage to the corresponding
The Moeller Easy512-AC-RC is a foundational control relay widely used for small-scale automation tasks. It bridges the gap between traditional hardwired relay logic and complex Programmable Logic Controllers (PLCs). This guide breaks down the essential programming methods, technical specifications, and wiring configurations found in the official manual.

Before programming, it is crucial to ensure proper wiring of the Easy512-AC-RC
Safety is paramount when working with line-voltage AC equipment. Ensure all upstream power sources are disconnected before wiring.
: Always isolate the power supply before changing terminal connections. Ensure your line and neutral connections match the L and N markings on the top housing profile. The "AC-RC" designation in the model name specifies
Use a dedicated Moeller/Eaton programming cable connected to the interface port under the front plastic cap.
Multi-function timers (On-delay, Off-delay, flashing). C1 to C4: Up/Down counters. 71 to 74: Weekly timers (utilizing the real-time clock). 81 to 84: Year timers. Step-by-Step Basic Wiring and Startup
You can program the unit directly using the integrated LCD screen and keypad. This method is ideal for quick on-site modifications or simple logic configurations. ) : These are dry contact relay outputs
