AutoQuiz: What Is the Fastest "Electronic" Method to Bring a DC Motor to a Full Stop?
In regenerative braking, all of the motor's energy is fed directly back into the AC power line. -
FeatureAutoQuiz: Unique Feature of a Pneumatic Differential Pressure Sensor/Transmitter
In a pneumatic transmitter, the nozzle faces a baffle, so, as the measured pressure increases, the baffle moves toward the nozzle. -
FeatureAutoQuiz: What Is the Definition of Restore Time in Industrial Maintenance?
The restore time includes all activities required to diagnose and repair the device. This includes diagnosing the problem, isolating the device from the system, traveling to the device, and repairing -
Feature
AutoQuiz: What Is the Condition When Controller Output Increases in Conjunction With a Controlled Variable Increase?
As pressure increases (controlled variable), the valve output would increase to open the valve in order to relieve the pressure. -
Feature
AutoQuiz: How to Program the Correct PLC Equation for a Pressure Transmitter
To scale the analog input, calculate the "% of the raw counts range" that is represented by the analog input, and multiply by the EU100% range, since the EU0% value is 0. -
Feature
AutoQuiz: How to Perform PLC Raw Count Calculations for Pressure Transmitters
A pressure transmitter is connected to the analog input card of a PLC. The 4-20mA input value from the transmitter is converted into equivalent raw counts. -
FeatureAutoQuiz: What Is the Purpose of an Optical Isolation Circuit on a Digital Input Card in a PLC I/O System?
