Time Delay Relays can be used to protect electrical equipment from overcurrent, create a pre-determined time lag between two contactors, and trigger a warning device. The SG125024 is a non-latching, DC Time Delay Relay from the TE Connectivity family of products. With adjustable timing from 0.3 to 15 seconds, It is designed for applications where an adjustable or selectable time delay is needed. It is suitable for use in panel or machine assembly, or as a replacement for mechanical timers.

The SG125024 is a solid-state dual sensitive DC Digital Timer Relay with time range adjusted by setting dip switch. It features optional normally open and normally closed pins and a green LED indicator that shows when the signal is received from the contactor. It is easy to install with its JST SMH-2F / 2P connector and a two-color terminal strip. It also features an adjustable delay time on/off trigger, adjustable time on/off delay function, and time hold function (push and hold) by the push and hold terminals.

The SG125024 has a wide variety of applications, including controlling start-up or shut-down of motors, pumps, conveying systems, and lighting systems. It can be used to trigger alarms or warning signals, as well as in medical equipment, audio/visual systems, and consumer electronics. It can also be used to control HVAC systems, generating systems, and emergency systems. The adjustable timing range from 0.3 to 15 seconds allows the timing to be adjusted to meet the needs of the application.

The working principle of the SG125024 is based on its construction. It has two detections – an I/O detection which detects the current state of the input voltage, and an O/P detection which detects which kind of signal is to be applied. When the input voltage is detected, the timing starts from 0 to 15 seconds (adjustable). Depending on the set mode, the output will stay either ON or OFF for the whole set time or just part of the set time. Upon completion of the time delay, the output will be switched on or off depending on whether the I/O detection is detected or not.

In summary, the SG125024 is a DC Digital Timer Relay with adjustable timing from 0.3 to 15 seconds and a wide variety of applications. It features optional normally open and normally closed pins, and a green LED indicator that shows when the signal is received from the contactor. Its working principle is based on the construct by which it has two detections and upon completion of time delay, the output will be switched on or off depending on whether the I/O detection is detected or not. It can be used to protect electrical equipment from overcurrent, create a pre-determined time lag between two contactors, and trigger a warning device.
