Universal digital indicator
BAU200
For programmable input signal
Universal single point digital indicator
• Suitable for front-mounting in control panel
• With LED display
• Input signal (type of signal and measuring range) can be set with buttons
• For all Siemens Building Technologies sensors
(LG-Ni 1000, T1, PT100, PT 1000, 0 ... 10 V)
• 0 ..10 V analog output signal
• For nominal voltage AC 24 V, 50/60 Hz
Application
The BAU200 universal digital indicator is suitable for mounting in the control panel front,
or in control panel doors or covers. It can be programmed for use with a wide range of
input signals.
Functions
The type of signal and measuring range can be programmed by use of the buttons
(see table on page 4).
The measured value is displayed digitally and transmitted as a 0…10 V signal.
The supply voltage, input signal and output signal are electrically isolated (see technical
data).
