Dual channel
NO/NC input
Dual
Channel
NO /NC
This function is for connecting a
safety device with a dual channel
NO/NC mechanism, such as a
non-contact interlock switch.
5-77
Dual channel
solid state input
Dual Channel
Solid State
This function is for connecting
safety devices with dual channel
solid state outputs (PNP output),
such as safety light curtain or
safety laser scanner.
