The driver is limited for short-circuit current and the driver outputs can be placed at a high impedance state through the thermal shutdown circuit
Four CHANNEL 12V ULN2003 BASED RELAY BOARD MODULE ultrasonic The transparent car chassis adds4 Channel 12V ULN2003 based Relay Board Relay board module is used for controlling higher current loads from your microcontroller development board, PC parallel port or Arduino Uno. This board has four (4) on board relay which can switch up to 7Amps. Relays terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by ULN2003 IC hence your input device, such as Arduino, is
