This simple temperature relay circuit can be used to signal a fire or setpoint for temperature monitoring function. You need to adjust P1 so that T1’s base voltage is 0.5V smaller than the emitter ...

The second circuit adds a relay contact to power the load so that the stop pushbutton does not conduct load current. The industrial relay suggested can handle 15A AC or DC (up to 30V). Note that ...

We often marvel at the many things a 555 can do. But [Zafer Yildiz] shows us that it can even take the place of a PCB. You’ll ...

1. The well-established relay-driving circuit uses an optocoupler to isolate the grounds and noise coupling between the low-voltage digital-control signal circuit (left) and the relay as load (right).

IXYS Integrated Circuits Division Introduces New Power Solid State Relay (SSR) with 5kv Isolation Voltage The CPC1907B Power Relay is ideal for Industrial Controls, Motor Controls and Security ...

The conclusion was that these relays might work for light duty projects, but for commercial projects or operating near the edge of the ratings, you want to give these a pass.

Technavio has announced the top five leading vendors in their recent global circuit breaker, fuse, and relay market report from 2017 to 2021.
