Omega Speaker Systems DPS3301 Output Connector PIN Assignment, Output Connector Pin Assignment

‘SIGNAL CONNECTOR’ in figure 4. Also indicated are the input signal’s positive and negative polarities for thermocouple connection. These markings are also on the printed circuit board in front of the connector. Care should be taken to connect the positive and negative legs of the signal source to the proper terminals on the connector. A wrong connection will result in incorrect process readings. (No polarity is necessary for RTD or thermistor).

OUTPUT CONNECTOR PIN ASSIGNMENT

Table 1 shows the output connector pin numbers and signal description. For convenience, the printed circuit board is labeled R1 through R7. Additionally, positive and negative outputs for open collector outputs are also indicated.
