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 ...

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 ...

The MAQ20-DORLY20 module offers 20 isolated SPST latching relay output channels that can switch between 2 A at 30 V and 0.4 A at 150 V. Each channel has contact state readback to verify the physical ...

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 ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TLP3910,” a photovoltaic-output photocoupler (“photovoltaic coupler”) housed in a thin SO6L package, ...

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 ...
