Two digits of 7 segment LED display
One pulse switch
Push buttons to generate inverting and non inverting pulses supported with de-bounce elimination
Data switches
Toggle switches and corresponding output point. When switch is set at “Down” position, the output is LOW level, contrarily it is to be 'High' level while setting at “Up” position
8ohm/0.5W to be used for load
Four channel adaptor
The two banana sockets and BNC jacks suitable for the trainer to be connected with peripherals
Sixteen bit LED display
Red LEDs separate input terminals. The LED will be lighted up when input is at “High level ”and it will be turned OFF when it is at “No Input” or at “Low level”
