Installation
Attach the DIN rail bracket to the AP8a and click it to the DIN rail. Provide for power supply by
applying a 2-pin cable to the power unit. Now the analog output of the AP8a is connected with the
DAQ system, the AP8a is equipped with 5B-compatible modules, and the signals cables are attached
to the terminal blocks (available under:
ZU7ST
), which are plugged into the input connectors of the
AP8a then.
Always turn off the power before changing the modules! Check for correct poling of the power
supply!

Connections and pin assignments
The available connections and different components of the AP8a board are shown in the following
figure of the board (view on top of the board (fitted with components), analog output connector top
right).

Power 5V or 9-40V
The power supply is applied to the 2-pin screw terminal of the AP8a (see
Figure 1).
The range of the supply voltage is selected at the 3-pin jumper on the
AP8a. If placed across the pad in the middle and the square pad, the
backplane must be supplied with +5V. If placed across the pad in the
middle and the round pad, a voltage in the range of +9..40V (default
setting ex works) can be used.
The power supply is provided with a reversible semi-conductor fuse (multifuse), which is turned off
when overloaded. To make the fuse work effectively again, get rid of the overload first before
disconnecting the AP8a from the power supply.
