Duty, model and compatibility

What is Klockner Moeller easy700?

Klockner Moeller easy700 is a programmable smart-relay series for small machines and control panels. It combines simple logic that would otherwise need timers, counters and several auxiliary relays in one device, serving applications that do not require a full-size PLC system.

The operating chain is straightforward: sensors and pushbuttons send states to the inputs; the controller scans those inputs, executes the user program held in memory and updates the outputs from the resulting decisions. Outputs command contactors, valves, indicators or other control devices. This scan repeats continuously so the machine reacts as conditions change.

Models and hardware

Models and system context: Verified model examples under this heading are EASY719 / EASY721; the associated system is easy700. The examples identify the documented product group; always confirm the complete order code, hardware issue and connection arrangement for the installed unit.

Programming software

Classic easy400–800 and MFD-Titan devices use easySoft/easySoft-Pro; easySafety uses the separate easySoft-Safety environment; easyE4 uses its supported easySoft release. Select both programming cable and project file for the device generation. See Klockner Moeller easySoft and easySoft-Pro for the detailed target and release guide.

Lifecycle and service status: This heading mainly covers a product series encountered when maintaining legacy Moeller systems. The existence of an archived manual does not mean the product is still manufactured; base replacement decisions on the complete code, program backup and wiring diagram.

Selection criteria: verify device generation, supply type, onboard I/O, expansion architecture, communication and program file together. A related series name or similar enclosure alone does not prove electrical or software compatibility.

Products that work with or should be compared with Klockner Moeller easy700 include Klockner Moeller easy400, Klockner Moeller easy600 and Klockner Moeller easy500. These links show a system relationship, not that the products are identical.

When researching programming, expansion or spares, also review Klockner Moeller easy800 and Klockner Moeller easy800 SmartWire-DT; make the final decision from the complete order code and the installed machine wiring.

Before commissioning

Commissioning check: before energising the equipment, verify supply, grounding, I/O or motor wiring, communication, software issue and the available backup.
