Circuits that fall under the requirements of Art. 725 are remote-control, signaling, and power-limited circuits that aren’t an integral part of a device or appliance. Article 725 includes circuits for ...

Fig. 1: The silicon-controlled rectifier One major aspect of development in broadcast transmitter technology and power electronics is in the area of power control. On the traditional transformer, we ...

Design Idea for a simple gated-osciallator circuit to limit MOSFET on-time using an An R-C time to limit On-time pulse period length and generates its own maximum permitted On/Off duty cycle. A power ...

How does the NEC control your signaling and control wiring requirements? Today's industrial facilities use a host of control circuits for motor control, instrumentation signals, and plant shutdown ...

With any low-power design, the designer has the choice between choosing low-power components or switching off the power to peripheral devices. When considering the choice of non-volatile flash ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

Selecting the right solution to optimize the distribution of power to the connected loads is imperative for maximum system uptime. Switches, breakers, remote signals across Ethernet and automated ...

Advancing GSM architectures many not seem like a sexy topic in an age where 2.5G and 3G technologies are the talk of the town. However, the reality is that like AMPS in the past GSM is becoming a base ...
