1. Description of easyE4 control relay
1.2 Function
1.2 Function
The easyE4 device is an electronic control relay.
With their compact cover dimensions – and a heavy-duty, flat, anti-glare front – the
base devices and expansions are ideal for industrial applications.

Programming languages: Ladder diagram (LD), Function Block Diagram (FBD),
Structured Text (ST), and easy Device Programming (EDP) on device and in
easySoft 8
easyE4 base devices combine the functions of a control relay and an input device in
one single unit
The Ethernet port makes it possible to integrate the base device into a network.
This allows the design of systems using high-speed controllers with decentralized
intelligence.
There is ladder diagram language version called easy Device Programming (EDP)
that you can use to put together a circuit diagram on the device.
In the case of devices with a display, you can enter the program as a circuit diagram
directly on the device by using the corresponding buttons. You can also program it on
your computer with the easySoft 8 programming software program (this option can
also be used for base devices without a display).
For example, you can:
l
Connect N/O and N/C contacts in series and in parallel
l
Connect output relays and markers.
l
Define outputs as coils, impulse relays, rising
