Product description
3.9.2
Output module UE410-4RO
The UE410-4RO has two control inputs (B1, B2). These inputs control two-by-two internal
relays that form two independent redundant shutdown paths.
Control input (B1) operates two internal relays and forms one redundant shutdown path
comprising:
•
two “safe enable current paths” (13/14, 23/24), dual-channel and floating,
•
one “safe enable current path” (Y14), dual-channel and not floating,
•
one “external device monitoring feedback circuit” (Y1/Y2), dual-channel and floating.
Control input (B2) operates two internal relays and forms one redundant shutdown path
comprising:
•
two “safe enable current paths” (33/34, 43/44), dual-channel and floating,
•
one “safe enable current path” (Y24), dual-channel and not floating,
•
one “external device monitoring feedback circuit” (Y3/Y4), dual-channel and floating.
The UE410-4RO therefore has twice the functionality of an UE410-2RO.
