Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

The PCI-1763UP has eight optically isolated digital inputs with 2,500-Vdc isolation protection for collecting digital inputs in noisy environments and eight Form-C relay actuators for on/off control.

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...
