Simple Relay Circuit

The following schematic illustrates the Simple Relay Circuit Diagram. When the switch is opened, the current flow through the electromagnet ceases and the magnetic field collapses and disappears. Since the attraction for the soft iron bar by the electromagnet no longer exists.

Mini-DIN 3 Connector Schematic Diagram

The following figure illustrates the Mini-DIN 3 Connector schematic diagram. This connector is applicable for Red Local Apple LocalTalk. Originally presented as AppleTalk Personal Network, LocalTalk used twisted pair cable with mini-DIN connector 3 pin.

Motorola VWA63 Auto Radio Circuit Diagram

Motorola VWA63 Auto Radio is an automotive type all-transistor superheterodyne AM radio for standard broadcast reception. The following schematic illustrates the Motorola VWA63 Auto Radio Circuit Diagram.

Connecting Pioneer BDP-440 3D Blu-ray Player to the Network thru LAN Interface

Connecting Pioneer BDP-440 3D Blu-ray Player to the Network thru LAN Interface. Connect the LAN (Ethernet jack 10BASE-T/100BASE-TX) terminal on this receiver to the LAN terminal on your router (with or without the built-in DHCP server function) with a straight LAN cable (CAT 5 or higher).

Simple Voltage Regulator Circuit Design using Zener Diode

Here is a typical schematic diagram of a Simple Voltage Regulator using Zener Diode. The reverse conduction voltage of a Zener diode is specified as VZ at a reverse current IZ, and the Zener’s reverse voltage will be fairly constant over a reasonable current range.
