Description: The kit is based around the ULN2003A IC, a 7-channel high voltage, high current relay driver. The inputs are TTL compatible so they can be connected to 5V. LO 0-0.8VDC. HI 2.4V - 12VDC. Operating voltage: 12V DC. The relay will be operated when either the LO input is low (0 – 0.8V) or the HI input is high (2.4V – 12V.). Two 12V relays, coil resistance 400 ohm are used. It is rated to switch 250VAC at 12A. However, because of the PCB track thickness and width we do not recommend using the relay to switch more than 5A. PCB size: 2 3/4"x1 3/4"
