The Moeller (now Eaton) EASY512-AC-RC is a foundational intelligent control relay used for small-scale automation in industrial and building environments. This programming manual overview provides the essential steps for local keypad configuration, software-based setup, and basic circuit design. Hardware Overview and Keypad Interface
The EASY512-AC-RC features a front-mounted LCD and a dedicated keypad for on-site programming without a PC. Keypad Buttons:
DEL/ALT: Used to delete elements or toggle between different circuit symbols and drawing tools.
ESC: Navigates back through menus or cancels current actions.
OK: Confirms selections and enters the main programming menu.
Cursor Disk: Navigates the 4-column-wide circuit grid and moves between menu items.
LCD Display: Provides a real-time status screen showing the state of inputs (I) and outputs (Q), as well as the current day and time on models with a clock. Local Programming: The Circuit Diagram
To begin programming directly on the device, navigate to the PROGRAM menu and select CIRCUIT DIAGRAM. The workspace consists of up to 128 rungs, with each rung allowing up to 3 contacts and 1 coil.
Adding Contacts: Position the cursor in the first three columns and press OK to select an input (e.g., I1). Use the ALT key to change the contact type to "normally closed" (indicated by an overbar).
Wiring Elements: To connect a contact to a coil, press ALT to activate the line drawing tool. Use the cursor disk to "draw" the connection across the grid.
Placing Coils: Coils must always be placed in the far-right fourth column. Press OK and use the cursor to select between standard output relays (Q), markers (M), or specialized function blocks like timers (T) and counters (C). Software Programming with easySoft
For complex logic, the easySoft-Basic software (part number EASY-SOFT-BASIC) is recommended.
Workflow: Programs are created in a graphical Ladder Logic environment. Users drag-and-drop elements onto the workspace, and the software automatically handles the wiring. The Moeller (now Eaton) EASY512-AC-RC is an intelligent
Simulation: Before transferring to the hardware, programs can be tested using the offline simulation mode to verify logic without risk to the machine.
Transfer: Connecting a PC requires a dedicated programming cable like the EASY-PC-CAB (serial) or EASY-USB-CAB (USB). Core Function Blocks
The EASY512 series includes several internal functions to replace traditional hardware:
Timers (T): Supports On-delay, Off-delay, single-pulse, and flashing modes. Time ranges from 0.01 seconds up to 99 hours.
Counters (C): Capable of counting up to 32,000 pulses in both up and down directions.
Markers (M): Internal "helper" relays used to store intermediate logic states or extend a rung if more than 3 contacts are needed.
Clock Controllers: Models with "RC" in the name include a real-time clock. You can program up to 4 on/off cycles per channel for specific days of the week. Wiring and Specifications Klockner Moeller EASY 512 Programming Instructions
