T75S1D112-24

Power relays are electrical switches that allow a low power signal to control or activate a larger electric current, enabling a control circuit to be switched on or off. The T75S1D112-24 Relay is part of this family and excels in providing a reliable, robust, and cost-effective solution to many control applications with currents in excess of two amps.

Key Features

• High sensing current – up to 24Amps
• High switching current – up to 10 Amps
• High switching voltage – 120/240VAC
• Small envelope – 40mm x 10mm x 16mm
• Fast response time – 1msec

The T75S1D112-24 is thus ideally suited for applications with high currents and associated short contact life. It is equipped with manual and automatic reset capabilities, as well as multiple contact points that can be independently controlled.

Application Field and Working Principle

T75S1D112-24 Relays can be used in numerous applications where current control is required. Automotive engineering is a prime use case, where relays are widely used to switch high current loads on and off, such as power windows, electric fuel pumps, and cooling fans, as well as trunk lid releases. Built-in features like automatic reset and the ability to chain multiple relays together allows for the reduction of wiring, creating a cost efficient and reliable control system.

The working principle of T75S1D112-24 is relatively straightforward. A low power signal (typically in the range of 5V-12V) is used to energize the relay. Internally, a solenoid energizes an armature which then moves a contact set, which in turn connects the two larger current wires, in this case, up to 24Amps. The low power “coil” signal can be interrupted to deactivate the relay.

Various Uses for Relay Switches

In addition to automotive applications like fuel and brake systems, relays are also used in electrical and industrial control systems. For instance, relays can be used for hot tub and swimming pool pump timers, HVAC systems, industrial machinery, and household appliance control systems. They can also be used for remote switching, such as in security systems, electric garage door openers, and remote power switches.

With its high sensing current of up to 24 Amps and its multiple contact points, T75S1D112-24 Relay is an effective choice for many power applications. It provides a reliable, robust, and cost-effective control solution, and is suitable for control systems with currents in excess of two amps.
