Impulse relay
An impulse relay is a relay which changes its switching state
and retains its new state (latched) when a voltage is applied
to the relay coil for a short time.
Input
The inputs are used to connect up external contacts. In the
circuit diagram, inputs are evaluated via contacts I1 to I12
and R1 to R12.
easy-AB, easy-DA and easy-DC can also receive analog data
via the inputs I7, I8 and I11, I 12.
Interface
The easy interface is used to exchange and save circuit
diagrams to a memory card or PC.
Each memory card contains one circuit diagram and its
associated easy settings.
The EASY-SOFT-BASIC software allows you to control easy
from your PC which is connected using the easy-PC-CAB
cable.
Local expansion
I/O expansion with the expansion unit (e.g. EASY620-DC-TE)
installed directly on the basic unit. The connector is always
supplied with the expansion unit.
Memory card
The memory card is used to store your easy circuit diagram,
together with its parameter and easy settings. The data on
the memory card will be retained, even if the power supply
fails or is switched off.
The memory card is inserted into the interface slot on the
easy device.
Mode
easy has two operating modes: RUN and STOP. RUN mode
is used to process your circuit diagram (with the controller
running continuously). In STOP mode you can create your
circuit diagrams.
