7.1.1 Testing DI
On System-1 connect one side of the switch to the DI on the Zlinx Xtreme I/O device and the other side of the switch to high or
ground depending on PNP or NPN configuration (see Figure 7-2). The LED corresponding to the DI should be ON

7.1.2 Testing DO (Relay O/P)
To test a “relay” output the following can be performed. See “Appendix E: Zlinx Xtreme I/O Models and Features” to find out
which modules are relay. On System-1 on the corresponding Zlinx Xtreme I/O device connect a Light through COM and NO
contact of the relay output (see Error! Reference source not found.3). Make sure to check the polarity of the LED while
connecting it. On System-2 perform contact closure on the corresponding DI. The relay output should turn ON and the Light
should turn ON

Testing AI in “Voltage” Mode
Connect an AA battery (1.5 VDC) on the AI-1 on System-1 (see Fig 7-4) and a voltmeter on the corresponding AO-1 on
System-2. Make sure the polarity is correct while connecting the battery. Measure the voltage on the Analog Output on
System-2. It has to indicate 1.5 VDC.
