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.
EZ-AB, EZ-DA and EZ-DC can also receive analog data via
the inputs I7, I8 and I11, I 12.
Interface The EZ 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 EZ settings.
The EZSoft software allows you to control EZ from your PC
which is connected using the EZ-PC-CAB cable.
Local expansion I/O expansion with the expansion unit (e.g. EZ620-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 EZ circuit diagram,
together with its parameter and EZ 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 EZ
device.
Mode EZ 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.
