Johnson Controls® produces environmental control systems for commercial buildings, as well as car seats, interior systems, and batteries. The electronics testing process requires modules that have stacking capability, a compact size, and DIN-rail mounts. Additionally, they require modules that are easy to interact with. For example, the I-7017 modules are used to read input data regarding voltage and current supply during the testing of various electronic parts. The I-7067 relay module is utilized for multiplexing (combining two or more information channels onto a common transmission medium) signals so that a certain line of products can be cycled. ICP DAS provided the quickest, simplest, and most manageable solution to meet the needs of Johnson Controls.
