Breakout board with a small relay monoscambio operating at 5 volts and its status LED. The contacts of the exchange (C, NC and NO), are connected to the pin-strip that allows you to insert the card on another circuit (this allows you to add a relay output by simply engaging breakout board as if it were a component of the base) . To the control input it must be applied a voltage referred to ground (GND) of a value comprised between 3 and 12 volts; this means that we can control the board with a logic level taken from circuits both at TTL logic, both operating at 3.3 volts, with both CMOS logic operating at 12 volts. The current absorbed by the entry of the command is of the order of 0.6 mA to 3.3 volts, 0,95 mA at 5 volts and 2.5 mA at 12 volts; a value can be supplied by any CMOS logic gate also. Power: 5 Vdc, absorption relay energized: 40 mA.
