Chapter 8 Appendix
8.1 Example of Safety Circuit for S/SX/SXD type
(Conforming to Safety Category)
S/SX/SDX types (global specifications) are the controllers applicable for the safety categories.
In this section, shows samples of circuit diagrams for Categories 3 and 4, however, it is not
possible for us to confirm the conformation to the safety categories in the system that you
construct. Therefore, it is necessary to construct the circuit that conforms to the safety
category required for the system with the circuit examples as a reference.
