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 chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

Relays and solenoids are available with many different voltage ratings. Most factory- and process-automation equipment operates from 24-V supplies. However, customers may have control signals for a ...

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 ...

A transformer switching onto a line can sometimes cause a circuit breaker to trip or a fuse to blow. This phenomenon occurs even if the transformer presents no load, such as when the secondary is open ...

Intelligent Motor Protection for Modern Industrial Plants The NewElec MA-Relay is engineered to protect your motors from the ...

Basler has updated its Time-Current Characteristic Curves spreadsheet tool to include new curves. The spreadsheet can be used to convert existing time dial settings for old induction disk relays to ...
