The output signal of the fully modulated measuring amplifier is
available at connection 5 and 6 (operating voltage zero). The permitted load
resistance must be
If the MC2A is equipped with a current output stage, an impressed current of
+ 4 mA (variable zero point) to 20 mA (nominal output signal).
The permissible ballast resistance
the mode of operation − voltage output or current output − is selected (circle
visible, position 1¢ voltage output).

3.6 Supply voltage

The measuring amplifier MC2A is suitable for connection to an unstabilized
DC voltage of + 10.5 V ... 26 V. The maximum current drain will be < 75mA.
For thermal dissipation reasons it is advisable to select a voltage less than
20 V. The supply voltage shall be connected to clamps No. 8 and 9. The posi-
tive pole shall be No. 9.
The amplifier is protected against wrong polarities of the supply voltage.
WARNING
The power supply leads should only be attached to points 8 and 9 other-
wise damage may be caused to the amplifier.
