A simple circuit that drives up to four single-coil latching relays (Figure 2) includes a parallel-interface relay driver (U1) with open-drain outputs (Figure 3) and inductive-kickback protection.

This circuit wastes twice the power, in diode losses, of the circuit in Figure 1. Figure 3 You can wire a relay switch to pass power to your system with no power loss. D 2 clamps inductive kicks from ...

Built for performance and efficiency, the latching relays offer high current switching, low power consumption, and rugged reliability—ideal for automation, telecom, and industrial systems.

Siemens is expanding its family of Reyrolle protection devices with the launch of the 7SR46. Complementing an extensive portfolio of protection relays for distribution and industrial grids, the ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India ...

The most critical component of his circuit, the relay, is just a standard normally-closed relay that is rated at 20A. [Teodor] wired the relay so that it energizes its own coil whenever it is shut.

The J107E1 series standard 10A relay is available with a 12V or 24V coil and features a rugged construction. Contact arrangement is SPST or SPDT with a contact rating of 10A at 250 Vac and 30 Vdc ...
