Pulse-width modulation Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal.PWM (Sine–triangle pulse width modulation) signals are used in micro-inverter design (used in solar or wind power applications). These switching signals are fed to the FETs that are used in the device. The device's efficiency depends on the harmonic content of the PWM signal.

Powertrain control module A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the Transmission Control Unit, and the Body Control Module, for a total of three separate computers as an example.

Relay A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on another c

The Basics of Control Relays Relays are used to isolate one voltage level from another. A PLC may be used to control the operation of a medium-voltage motor, perhaps 2,300V or 4,160V. A relay is used to energize the starter, which, in turn, switches the motor voltage while the PLC controls the relay.

Relay Relay - Basic design and operation. 1  A simple electromagnetic relay consists of a coil of wire wrapped around a soft iron core (a solenoid), an iron yoke which provides a low reluctance path for magnetic flux, a movable iron armature, and one or more sets of contacts (there are two contacts in the relay pictured).

PCM Audio and Wave Files In the digital domain, PCM (P ulse C ode M odulation) is the most straightforward mechanism to store audio. The analog audio is sampled in accordance with the Nyquest theorem and the individual samples are stored sequentially in binary format. The wave file is the most common format for storing PCM data. But, before you dig into the internals of wave files, it would help to get some insights to the Interchange Format Files that form the basis for the wave file format.

What is interposing relay? Why is it used? Interposing Relay is the auxiliary relay which is used to isolate the two different systems/ devices. This could be because they have different 0V references, different voltages, AC vs. DC. For example, let's say the relay of a PLC can only avail 1 A at 110 VAC, but the Controller which is to be connected to the relay requires 1.5 A at 110 VAC.

- If there are no reference pulses, the PCM turns the fuel pump off after about 2-3 seconds. The PCM controls the fuel pump relay by applying B+ to the control circuit via an internal switch called a driver.

Automotive Relays and How They Work Automotive Relays and How They Work. Automotive relays of all shapes and sizes can be found in just about every car, truck, and even boats. Relays in general are used to enable a low amperage circuit to switch on or off a higher amperage circuit, like turning on your headlights.f you were to try and directly hook up your headlights to the headlight switch you would exceed the amperage rating of the switch, melt wires, and risk an electrical fire. Relays are also used to switch multiple things at the same time using one output.
