Important
I
f you want an electronic controller to be able to switch higher currents and at the
same time you need an insulation between the controller and the controlled
items, then a relay module is an indispensable help.
T
he module is very well suited to be connected to our kits K6711 (15 channel IR
receiver) and one or two times K8023.
For those two kits power can be taken direct from the relay module. The module
can also be used together with the open collector interface module K8000.
T
he module can of course also be used very well in other applications.
OPTIONS :
I
n its standard version the module contains 8 relays (K6714), but in the full
version the module (K6714-16) contains :
16 relays.
DIP switches for manual operation.
An indication LED per relay.
Two ULN2803 type transistor array (IC’s).
Y
ou can fit the standard module K6714 with another 8 relays (12V types) your-
self. However this requires the installation of additional screw connectors.
16. IMPORTANT :
The ULN2803 type transistor array allows you to control the relays
direct from a TTL or CMOS. For controlling the relay with open col-
lector control, don’t mount the transistors arrays.
