External Digital I/O Module

The Vector External Digital I/O Module (EDI/O) provides 16 discrete inputs and outputs with a 24 VDC reference. The Vector Digital I/O Module can be used for interfacing the leak tester to the PLC (Programmable Logic Controller) I/O as well as to fixture actuators and discrete devices.

Advanced Leak Tester Option (ALD)

Uson's Vector Advanced Leak Tester Option (ALD) permits leak testing during the adiabatic cooling phase. The Advanced Leak Tester generates and stores a model of the adiabatic cooling cycle of the component being tested. During testing, the Advanced Leak Tester's Leak Rate Model is used to accurately determine the leak rate of the part under test, resulting in less time to test and more accurate results.
