2-4 Expansion Unit
Note: 1. When two or more Units are connected by logical AND, the operating time and response time are the sum total of the operating times and response
times, respectively, of all the Units connected by logical AND.
2. This does not include the operating time or response time of Safety Guard Switching Units (G9SX-AD/-ADA/-NSA/-GS) that are connected.
3. This does not include the operating time or response time of internal relays in the G9SX-EX-@.
4. For the G9SX-@-RT (with screw terminals) only.
