Digital I/O Adapter PCB
for XL2 Audio and Acoustic Analyzer
The XL2 Audio and Acoustic Analyzer together with the Digital I/O
Adapter control external peripherals, such as displaying exceeding
sound levels on a big red-orange-green lamp. Measurements canbe started by an external switch. The Digital I/O Adapter connects
to the digital I/O interface of the XL2 Analyzer.
Key Features• Offers 4 outputs for control of external peripherals• Switches up to 250 VAC at 6 A• Offers an input to start FFT or 1/12 Octave measurement• Controlled by XL2 Audio and Acoustic Analyzer

P r o d u c t DataABConnecting a switch:

CSpecifications+Outputs• 4 individual outputs• Connector type: mounting Connecting
terminals an active Output:• Terminals mutually isolated• Relay outputs switching @• resistive load up to 250 VAC / 6 Ampere floating• inductive load up to 250 VAC / 3 A, 24 VDC / 2 AInputs

IN1• 4 individual inputs• The XL2 sets markers 1 - 4 in the log file during
noise level logging
GNDthe pass/fail measure• XL2 uses input 1 to start
ment in the FFT and 1/12 Octave function(requires Spectral Limits Option)
J7• Connector type: mounting terminals• Terminals mutually isolated• Input level 3.3 - 24 VDC / 1.5 mA• Inputs have common ground with external
