POWER SUPPLY CIRCUIT:
RESET CIRCUIT:
CLOCK CIRCUIT:
INPUT/OUTPUT:
The power supply of AVR-IO-M16 is taken from Power jack connector. The
center pin is positive. The voltage range is +12-14VDC. The consumption is
20 mA with no relays switched on
AVR-IO-M16 reset circuit is made with ZM33064 with typical threshold
4.5V. When the voltage falls bellow that minimum, the MSU resets.
Quartz crystal 16MHz for maximum performance is connected to ATMega16
pin 7 (XTAL2) and pin 8 (XTAL1).
Four optoisplated digital inputs IN1-IN4.
Four red status LEDs for the digital inputs – from LED1 to LED4.
Four relays – from REL1 to REL2.
Four red status LEDs for the relays – from LED5 to LED8.
One red user status LED with name LED9, connected to ATMega16 pin 16
(OC2/PD7).
