Each module offers two different types of input and
output. The inputs monitor whether or not a switching
state has changed and indicate the current status (e.g.
contact open or closed).
12 inputs:
• 6 digital, TTL-compatible inputs (I7 - I12)
• 6 analogue (/digital) inputs (I1 - I6)
The digital inputs can be used to connect push-buttons
or wired door/window contacts, for example.
The analogue inputs are capable of measuring input
voltages of up to 10 V. This makes them ideal for
recording sensor data. With the HomeMatic central
control unit, they can also be configured as digital
inputs.
In addition, for the inputs I7 - I12 frequencies of up to
250 Hz can be measured.
14 outputs:
• 8 open collector switching outputs
• 6 relay switching outputs
The open collector switching outputs OC1 - OC8 make
it possible to control consumers up to 24 V/50 mA.
