I am attempting to use the K2633 as a test device to test operation of a Fitre E-Tell phone. Looking for help with input and output to these two devices. I need the LED’s to light when calls are made and have a test button to implement a call. I can’t attach the diagrams but can send via email. If someone can tell me how to insert the diagram I will gladly do so. The img button only puts a link for pics but they are not on any website to link to.
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.
Features:
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.
