WebApr 4, 2024 · TDO contact opens at end of timing period. Timing Relay – TDPU indicates timing period starts when coil is energized. TDDO indicates timing period starts when coil is de-energized. O=Operate; R=reset; TC=trip coil; CC=closing coil. (Coils may be seperated on diagram) If shown closed, terminals must be added. WebJan 25, 2024 · RL1 is a relay, a type of electrically-actuated mechanical switch. The swirls are the relay's coil, and the two lines indicate that it's wrapped around a magnetic core. The thing labelled N/O and N/C is also part of the relay; N/O is "normally open", which means that switch contact is open, or disconnected, when the relay coil is not energized.

WebTiming relay has a device that delays the instant switching on or off of the armature when power is applied to or removed from the relay. Some relays are built with a kind of “shock absorber” system connected to the armature, which prevents instant complete movement when the coil is either energized or de-energized. Types of time delay relay:
