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).

Ordering When ordering, please specify the quantity, product name and type code. Example:
1 BAU200 universal digital indicator
Mechanical design Multi-part plastic housing, comprising: − LED 3 ½ -digit display (max. display range 1999 / –1999) − Front panel with membrane keyboard − PCB with screw terminals
Mounting and installation Mounting instructions (CE1G5312X) are enclosed with the unit. The digital indicator is suitable for mounting in the control panel front, or in control panel doors or covers. It is pushed into the cut-out from the front. It is secured without screws by means of a slide fitting on the sides of the unit.
Disposal The device includes electrical and electronic components and must not be disposed of as domestic waste. Current local legislation must be observed.
Commissioning Refer to the operating instructions enclosed with the device (CE1G5312) for information on the settings.
