WebREVIEW: Time 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 ... WebEach Form-C contact set offers a choice of either normally-open or normally-closed contacts, and the two sets (two “poles”) are electrically isolated from each other so they may be used in different circuits. Two common packages for industrial relays are the so-called octal relay and the ice cube relay. increased anger during pregnancy

Everything else for both of these relays are just normally-open and normally-closed contacts for you to wire however you need to for your specific application. WebNormally-closed contacts are equivalent to a NOT gate (inverter). We can build combinational logic functions by grouping contacts in series-parallel arrangements, as well. In the following example, we have an Exclusive-OR function built from a combination of AND, OR, and inverter (NOT) gates:
