  • Page 9 Figure 3. Connecting Wires to the NI 9219E Spring-Terminal Connectors Connecting TEDS Channels The NI 9219E supports only Class II TEDS sensors. Connect the two TEDS lines to TEDS Data (T+) and TEDS COM (T–) and ensure that neither T+ nor T– is tied in common to any of the signal inputs (terminals 3 through 6) on the NI 9219E.
  • Page 10 Connecting Signal Sources to the NI 9219E You can connect ground-referenced or floating signal sources to the NI 9219E. If you make a floating connection between the signal source and the NI 9219E, make sure the voltages on the positive and negative connections are within the channel-to-earth working voltage range to ensure proper operation of the NI 9219E.

  • Page 13 Voltage and Current Modes In Voltage mode, the ADC measures voltage across the HI and LO terminals. In Current mode, the NI 9219E computes current from the voltage that the ADC measures across an internal shunt resistor. – NI 9219E...
  • Page 14 4-Wire Resistance and 4-Wire RTD Modes In 4-Wire Resistance and 4-Wire RTD modes, the NI 9219E sources a current, which varies based on the resistance of the load, between the EX+ and EX– terminals. The NI 9219E computes measured resistance from the resulting voltage reading. Lead wire...
  • Page 15 This mode compensates for lead wire resistance in hardware if all the lead wires have the same resistance. The NI 9219E applies a gain of 2x to the voltage across the negative lead wire and the ADC uses this voltage as the negative reference to cancel the resistance error across the positive lead wire.
  • Page 16 In 2-Wire Resistance and Quarter-Bridge modes, the NI 9219E sources a current, which varies based on the resistance of the load, between the HI and LO terminals. The NI 9219E computes measured resistance from the resulting voltage reading. 2-Wire Resistance and Quarter-Bridge modes do not compensate for lead wire resistance.

  • Page 18 Thermocouple Mode In Thermocouple mode, the NI 9219E uses the ±125 mV range of the ADC to return a voltage reading. Use shielded cables and twisted pair wiring and ground the shielded cables. Each channel has a built-in thermistor for cold-junction compensation (CJC) calculations.
  • Page 19 Refer to Figure 7 for an illustration of the connections. Open Contact Mode In Open Contact mode, the NI 9219E sources a current between the HI and LO terminals and determines if the two terminals are open or closed based on the measured current through the terminals.
