This is a simple circuit which I built to one of my audio amplifier projects to control the speaker output relay. The purpose of this circuit is to control the relay which turns on the speaker output ...

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 ...

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 ...

Designed for high-voltage protection in industrial control and monitoring applications, the PCIe-IDIO-24 PCI Express I/O card boasts 24 optically isolated digital inputs and 24 solid-state FET relay ...
