Overcurrent Protection

In case of a short-circuit of the sensor supply output to ground, the sensor sup-
ply of this channel automatically switches off. Each sensor supply output is
protected against overvoltages. Exceeding the maximum value trips a fuse.
The short-circuit detection of each channel is supplemented by a monitoring of
the permissible total output of all sensor supply voltage channels. If the permis-
sible total output is exceeded, all channels are switched off.
7.2.4

Overload Detection

The application program receives analyzable, channel-specific information in
case of short-circuits, a tripped fuse and a violation of the permissible total out-
put.
7.3

Assignment of Channels

The sensor supply voltage of each channel can be connected to analog or dig-
ital sensors.
7.4

Electrical Isolation

The sensor supply voltage channels are not electrically isolated against each
other. The sensor supply voltage channels are electrically isolated as channel
group to the housing of the module.
NOTE
The supply voltages of the sensors are not electrically isolated to the operat-
ing voltage of the module.
7.5

Behavior for Rapid Prototyping Applications

NOTE
For rapid prototyping applications, it is recommended to use the "On Power
On" setting.
This configuration ensures that the sensor supply voltage is already present at
the connected sensors before the start of the RP model when switching on the
module. If the sensor supply voltage channels are not configured as described
above, the already existing sensor voltage is briefly interrupted at the start of
the RP model on the ES910.
