The "N-EM" are a series of emulators that provide the students the required hardware to emulate the most common automatic systems.
The "N-EM" modules are designed to work with the "AE-PLC" units to obtain the fundamental knowledge of PLC programing, PLC management, etc.
"N-EM-CA" represents a three floor elevator, which emulates the control of the movement of the elevator cabin, the opening and closing of the doors, the indicators of an elevator control panel, etc. The different pushbuttons emulate the request of elevator in each floor, the people detector when someone enters and exits the elevator cabin, etc.
