This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil ...

This low current relay circuit is designed to be used in battery operated electronic devices. Its operating current is in micro amperes (µA). This is done by using a bistable relay and adding some ...

Programmable logic controllers (PLCs) and computer-based controllers are great for handling logic and data-collection tasks for industrial controls. But when it comes to driving motors, heaters, ...

Suited for use in telecomm, instrumentation and industrial control systems, The PVT412A Series microelectronic relays (MERs) have two times more load current capability at ±400V off-state blocking ...

Equipped with two release-current paths and one signal-current path and with reinforced insulation separating the paths, the PSR safety relays are said to provide reliable protection for any and all ...

The ADAM-6066 is a high current relay output module designed to meet the requirements of power switching applications. The ADAM-6066’s six relay output channels are rated at 5A at 240VDC, and support ...

One type of starting relay used on fractional horsepower compressors is the positive temperature coefficient (PTC) relay. It performs the same function as a current relay or potential relay but in a ...
