QUAD RELAY CARD

Assembly Manual

Illustrated Assembly Manual (English)

Connecting a number of relays to the outputs of an electronic network may seem very simple, but in reality it might possibly create some problems regarding the cabling. This kit provides an attractive and compact alternative. Moreover, it can be assembled and connected very rapidly.

QUAD TRIAC SWITCH CARD

Relays are usually used to switch AC voltages by means of an electronic control because of their simplicity. However, when switching occurs too frequently or too quickly the life time of the contact points is shortened considerably. This can be solved perfectly by replacing the relays with a triac. Using optocouplers, the entire interface network remains electrically isolated from the voltage that has to be switched.

Dual HI / LO Switching Relay Board

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"
