Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop.

The circuit uses a Vishay V34836 infrared receiver to pick up the invisible signals that are sent from a remote control. A Microchip 12F683 processes the data and has two main output modes.

Over long cable runs, an isolated 4-to-20-mA current loop offers robust noise immunity and tolerance. This characteristic makes it popular for analog data transmission in noisy ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

1. A simple, widely used current limiter consists of a current sensor (usually a low-value sense resistor), a control circuit, and a pass transistor.

Circuit provides constant-current load for testing batteries Simple dual constant-current load tests low-current power supplies Prevent 9V cells from excessive drain with this battery monitor Design a ...

Short circuit current ratings should not be overlooked during panel design. Negative impacts can occur to production, equipment and, worst case, plant personnel.

A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient machine-learning hardware.
