Important Note
A transmitter with 9-36 V DC cannot be operated with alternating current, just
as it is impossible to operate a 230 V AC transmitter with 9-36 V direct current.
When operated with alternating current, the direct current supply clamps b2 and
b3 both provide a voltage of 24 V and a maximum capacity of 100 mA (turn on
24 V switch!).
Please note, when using this supply voltage (e.g. for digital inputs with control
signals), it must not be shielded through the complete switchgear in order to
maintain disturbing interferences on a low level.
