9-6 ADS TRITON+ Manual
Connecting the positive and negative wires from the third-party device to
Terminals 1 and 2 (analog input terminals) on the I/O terminal block
Connect the other ends of the positive and negative
wires to the third-party device based on the vendor’s
specifications.
Close and latch the door to the XIO.
4. Restore power to the customer’s instrument or device and
the ADS XIO.
5. Verify that adding the ADS equipment will not add too
much load to the analog signal loop. The XIO input adds
22 ohms to the loop. If too much load is added, the signal
will clip and cause the data to flat line at a lower level than
the true peak, which will result in understated peak levels
or flows. If only one device is connected to the analog
signal, sufficient current is probably available to drive the
XIO input. If more than two devices are attached to the
analog signal loop, ADS strongly recommends load testing
the loop.
