Relay Mounting Style

Socket have pins that plug into relay sockets to make electrical connections with circuits. They don't require tools for removal or installation and are ideal for applications where many relays are installed or periodically changed.
Surface have mounting features that secure with screws on surfaces and walls. They prevent relays from moving due to vibration and impacts.
Panel Door installs through cutouts on panel doors. Their user-interfacing side is visible on the outside of the panel door, while their socket connection is protected inside.

Delay Function Group

Cycling/Flashing upon application of an input voltage, a time delay begins to energize or de-energize the relay until the input voltage is removed. The time delay or period of time where the relay is energized or de-energized may be made equal or independent of one another during the cycle.
Off Delay upon application of input voltage, the output is energized. When the input voltage is removed, the time delay period begins. The contacts stay in the transferred position until the timing period ends when the output becomes de-energized. The contacts then return to their original position, and the unit is ready for a new cycle.
On Delay when power is applied to the coil, the on-delay timing period begins. The contacts do not transfer at this time. At the end of the on-delay period, the contacts transfer, connecting (normally open contacts) or disconnecting (normally closed contacts) the load. The contacts stay in the transferred state until power is removed from the coil. They then return to their original state, and the unit is ready for a new cycle.
Watchdog upon application of an input voltage, the time-delay relay is ready to accept trigger signals. Upon application of the trigger signal, the relay is energized and the preset time begins. At the end of the preset time, the relay is de-energized unless the trigger signal is closed and opened prior to time out (before preset time elapses). Continuous cycling of the trigger signal at a rate faster than the preset time will cause the relay to remain energized.
Multi-Function indicates the relay has more than one timing functionality that can be selected.

Contact Form

SPST-NC represents a single-pole, single-throw switch. They control one circuit and have contacts that are normally closed (NC).
SPST-NO represents a single-pole, single-throw switch. They control one circuit and have contacts that are normally open (NO).
SPDT represents a single-pole, double-throw switch. They control one circuit and have changeover contacts.
DPST-NO represents a double-pole, single-throw switch. They control two circuits and have normally open (NO) contacts.
DPDT represents a double-pole, double-throw switch. They control two circuits and have changeover contacts.
4PDT represents a four-pole, double-throw switch. They control four circuits and have changeover contacts.
