Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.
In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
