WebTime delay relays are built in these four basic modes of contact operation: 1: Normally-open, timed-closed. Abbreviated “NOTC”, these relays open immediately upon coil de-energization and close only if the coil is continuously energized for the time duration period. Also called normally-open, on-delay relays. 2: Normally-open, timed-open. Web20 de jul. de 2024 · This XIC instruction “asks” the processor of the PLC to examine if the contact is closed, which is the same as saying that power is now able to flow through this normally open contact. Think about it like this: if the contact looks as it does above (normally open), no power can flow through this open contact; however, if the contact …
