Active Setting Group Switching Example 2
Previous SEL relays (e.g., SEL-321 and SEL-251 Relays) have multiple settings groups
controlled by the assertion of three optoisolated inputs (e.g., IN101, IN102, and IN103) in
different combinations as shown in Table SECTION 7: .6.

The SEL-351P can be programmed to operate similarly. Use three optoisolated inputs to switch
between the six setting groups in the SEL-351P. In this example, optoisolated inputs IN101,
