By Patrick Hoppe
In this interactive object, learners answer nine questions about series and parallel circuits. Immediate feedback is provided.
By Terry Bartelt
This animated lesson shows the operation of timer-on and timer-off delay relays used in ladder circuit operate.
Overflow and Underflow for Signed Binary Numbers
By John Casey, Terry Bartelt, Terry Fleischman
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
Oscilloscope Phase Shift Measurements (Screencast)
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
Pneumatic Air Conservation
By Terry Bartelt, Stephen Schneider
In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.
Pneumatic Directional Control Valves
In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.
Pneumatic Cylinder Flow Control
Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.
The Air Pilot
In this animated object, learners examine the operation of a pneumatic directional control valve using air pilot lines.
Manual Control of a Reciprocation Circuit
This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
