Inputs
The CLM has 112 inputs.
All CLM input signals are galvanically isolated from the control using an
opto-electronic coupler.
The signal voltage of the inputs is +24 V external voltage. Under no
circumstances may the CLM’s 24 V supply voltage be used to supply
power to the inputs.
The current consumption of each input is approximately 8 mA at +24 V
external voltage.

Fig. 9-2: Signal Level of the Inputs
The terms ’1,’ ’On’ or ’Activated’ can all be defined by 24 V signal level.
The terms ’0,’ ’Off’ or ’Deactivated’ can all be defined by 0V signal level.
Depending upon the function to be initiated, the CLM differentiates
between two signal types:
This function is shown as long as the corresponding signal level is
constantly (statically) present. Most functions are ’active high,’ which
means they are active at signal level ’1.’ A few functions are ’active low,’
which means they are active at signal level ’0.’ To differentiate, the ’active
low’ functions have a "NOT" line over their descriptions.
This function is not dependent on a constantly present signal level. This
function is activated by a rising signal edge (signal level increases from ’0’
to ’1’) or a falling signal edge (signal level decreases from ’1’ to ’0’).
