The connection of a few relays to the outputs of an electronic circuit might be theoretically very simple, but practically it may lead to a very complicated matter with all possible results. This kit is an attractive and compact alternativ, fast to construct and to mount. It can be used with open collector circuits.
Four relay outputs, single pole invertors
Max. load : 240V AC / 3A resistive
9V DC / 300 mA power supply
Four control-LED’s are provided
Is controlled by an open collector output (9V/15 mA)
Dimensions : 76 x 69 x 25 mm.
