PDA • Operating Instructions 4. Operating Principle KOBOLD pressure indicator/transmitter series PDA, are cost effective electronic pressure indicator/transmitters with digital indication of actual pressure. An analogue output (0)4 - 20 mA is available for remote transmission of the measured value. The device is optionally available in addition with a switching output.
• Mating plugs with different cable lengths are available as options. Important! The instrument electronics may be damaged if the cable connections are connected incorrectly. 7.1. Connector pin assignment PDA-15... PDA-15 Not connected +Vs/+ Supply 0 V / GND...
