Achieve max electric fuel pump output and safety using a relay plus an oil pressure safety switch. Achieving maximum output and safety with a custom-wired electric fuel pump requires a properly ...

Addressing the requirements of power switching applications, the ADAM-6066 relay-output module includes Ethernet connectivity, an embedded web server for remote monitoring, and support for Modbus/TCP ...

No matter what the application is, when a definite-purpose solution is required, time delay relays (TDRs) can provide simple, reliable, and economical control. Adjusting the delay time is often as ...

LIBERTY, S.C. – The REL-32.PCI, a 32-output digital I/O interface for the PCI bus, has been added to the Sealevel Systems Inc. product line. The unit provides 32 reed-relay outputs, which can be used ...

This circuit is designed to provide delayed relay switching action at power on. The delay is a function of the time constant produced by the combination of R1 and C1. At power on, C1 charges slowly ...

Inspired by input from panel builders, system integrators and end users around the world, Rockwell Automation engineers developed the new Allen-Bradley E300 electronic overload relay. The E300 ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs. The Click C0-04TRS-10 ($54.00) is a ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
