IO tester with 6 channels


This unit is used for simulating inputs and outputs when a AVR module is complete, before installation. The module is power by a 5/12V power supply trough plugs in the back. Every input has two LEDs, one green and one red. If both are lit this means that the output is not active. If one the green LED is lit it's a positive signal on the input, and red if it's negative. The outputs are connected to small toggle switches, and can be used N.O or N.C The switch on the left reverses the polarity of the outputs.
