Dual Channel
Dual channel safety monitoring functions require two independent circuit
connections to the CR30. Dual channel inputs are used for medium and high risk
applications.
You can modify the number and types of inputs:
•
2 N.C.
•
2 OSSD
•
1N.C./1 N.O.
The available input selections for the dual-channel OSSD and two N.C.
inputs are:
•
EI_00…EI_11 (embedded input terminals 00…11)
•
MP_12…MP_17 (multi-purpose terminals 12…17)
The available input selections for the N.O. contact are:
•
MP_12…MP_17 (multi-purpose terminals 12…17)
