Information on this product
5.2.4.3
”E/A DISK R2ED” and ”E/A DISK R4ED“
I/O module
Features:
• 26 discrete inputs (24V
DC
)
• 1 output as switched relay (1 x ON)
• 18 discrete outputs (24V
DC
)
Function:
•
Coupling of discrete I/O signals.
The I/O modules EA DISK R2ED and EA DISK R4ED are identical
except for the connector designations (EA DISK R2ED: X1x; EA
DISK R4ED: X2x) and an internal coding.
If both are used in a WT, the I/O signals used are permanently cou­
pled to the respective module. That is why all I/O signals always ap­
pear at the same I/O module even after exchanging the slots of both
modules.
