2.0 Connecting a transducer to the DATUM 2000
Note: If you purchased your Datum 2000™ factory calibrated with a Setra pressure
transducer or transmitter, a 10 foot cable/connector assembly has been provided.
Therefore, this section may not be applicable. Go to page 7.
The DATUM 2000™ has two groups of input terminals, one for each channel. Figure
B (page 6) shows the terminal block connector on the back of the DATUM 2000™
and describes each position of the connector. Figure A shows a typical setup of a
DATUM 2000™ with a single transducer.
The DATUM 2000™ provides a ground referenced 12 volt and 24 volt excitation. The
24 volt excitation is available on pins 5 and 11. The 12 volt excitation is available
only on pin 10. (If two 12 volt transducers [transmitters] are being used, both
units must be connected to pin 10). DO NOT USE THE EXCITATION FROM THE
METER TO POWER ANY OTHER DEVICE BESIDES THE 1 OR 2 TRANSDUCERS OR
TRANSMITTERS THAT THE METER IS DISPLAYING. UNDER NO CIRCUMSTANCES
SHOULD MORE THAN 60 MA BE DRAWN FROM THE DATUM.
2.1 Transmitters (2 wire devices)
Connect the + excitation to pin 5 (CH2: pin 11) to supply 24 volts to the transmitter.
Connect the - excitation to pin 8 (CH2: pin 14) to return the signal to the DATUM
2000™.
2.2 Transducers (3 wire or 3 terminal devices)
Connect the + excitation to pin 5 (CH2: pin 11) to supply 24 volts to the transducer.
IF YOUR TRANSDUCER REQUIRES 12 VOLT EXCITATION, CONNECT THE +
EXCITATION TO PIN 10 (CH2: PIN10).
Connect the - excitation to ground, pin 9 (CH2: pin 15).
Connect the + output to +IN, pin 6
*
(CH2: pin 12).
Connect the -IN terminal, pin 7
*
(CH2: pin 13) to ground, pin 9 (CH2: pin 15).
Connect the shield to ground, pin 9 (CH2: pin 15).
