This elegantly simple analog tester will save hours of troubleshooting. If a sensor is suspect, remove the cable and connect the tester. If the LED illuminates this confirms the circuit supply and cable are good. The tester simulates a midrange 4 to 20 milliamp analog signal. The technician can confirm that the control system software displays the expected value.
In a few seconds, this device will determine if the problem is the cable, the sensor or the software.
This works with systems that have a 6S connector with 24 volt dc supply power on pin A and Signal on pin B.
