In addition to configurable I/O, the LPS-O relay includes the capability for the design of custom logic. This logic
may be used to supplement or to replace the built-in scheme logic. The programmable logic includes the fol-
lowing: up to 40 logic gates (AND, OR, NOT), each with up to 4 inputs; 8 programmable timers, each with a
settable pickup and dropout delay; 8 counters; and 8 latches.
