10.10.3 Digital Outputs<br />
The following digital output circuits are available:<br />
• Open emitter outputs, switches to +24 V (L2+)<br />

<strong>MSC</strong> <strong>II</strong><br />
Figure 57: Basic Wiring Diagram of a Digital Open Emitter/Collector Output of the <strong>MSC</strong> <strong>II</strong><br />
A digital open emitter output in the 1 state (conductive) connects the attached<br />
load R L to the power supply terminal-L2+.<br />
10.10.3.1 Dependence on the 'Outputs Enabled' Signal<br />
If the digital output 'Outputs Enabled' is in the 0 state (LED «OutEN» does not<br />
illuminate), all other outputs are disabled.<br />
In this case, although the internal states of the digital outputs are shown on<br />
the front panel status LEDs «I/O1»…«I/O4» of the <strong>MSC</strong> <strong>II</strong> control module,<br />
they are not connected through to the output.<br />

10.10.3.2 Current Limiting and Overload Protection<br />
L2+<br />
I/Ox,<br />
OutEN<br />
All digital outputs are protected by an integrated power limiter and a thermal<br />
overload protection device.<br />
In an overload condition, the affected output will be automatically disabled.<br />
After the output stage has been finished thermal cooling it returns to normal<br />
operation. If the overload is still connected, then the disable will happen<br />
again.<br />
A protective circuit with a limiting voltage of 50 V with respect to +24 V (L2+)<br />
for open emitter outputs protects all outputs against induced voltage spikes<br />
when there are inductive loads.<br />
