DC Volts, AC Volts, Frequency, and Thermocouples
Any analog input channel (0 through 20) can be used to measure dc volts, ac volts, or
frequency. For channel 0, use the two terminals on the front panel. For channels 1
through 20, use the H (high) and L (low) inputs on the rear panel Input Module.
Note
The terminals for channel 0 on the front panel do not support
thermocouple measurements.
Front panel channel 0 and Input Module channels 1 and 11 accept a maximum input of
300V dc or ac rms. All other channels (2 through 10 and 12 through 20) accept a
maximum of 150V dc or ac rms.
Use the following procedure for connections to the Input Module:
1. Remove the Input Module from the rear panel.
2. Loosen the two large screws on top and open the module.
3. Connect wires to H (high) and L (low) terminals for each channel.
4. Thread these wires through the strain-relief pins and out the back of the module.
Refer to Figure 3-2.
5. Close the module cover, secure the screws, and put the module back in the
instrument.
