Expanding EZD
You can expand EZD with EZ models EZ618-..-RE,
EZ620-D.-TE, EZ202-RE locally or use the EZ200-EZ
coupling module for remote expansion with EZ600 expansion.
All available bus interface devices such as EZ204-DP,
EZ221-CO, EZ205-ASI or EZ222-DN can be used if present.
Install the units and connect the inputs and outputs as
described (see
Section “Connecting the expansion unit”
Page 47).
You process the inputs of the expansion devices as contacts
in the EZD circuit diagram in the same way as you process the
inputs of the basic unit. The input contacts are assigned the
operand designations R1 to R12.
R15 and R16 are the group fault inputs of the transistor
expansion unit (
Section “Monitoring of short-circuit/
overload with EZ..-D.-T..”, Page 393).
The outputs are processed as relay coils or contacts like the
outputs in the basic unit. The output relays are S1 to S8.
How is an expansion unit recognized?
If at least one
R ..
contact or
S ..
coil/contact is used in
the circuit diagram, the basic unit assumes that an expansion
unit is connected.

EZ618-..-RE provides the outputs S1 to S6. The other
outputs S7, S8 can be used internally.
