GE WES5162-9101 Multifunctional I/O card

The figure below illustrates the recommended connections when using EMC compliant products. Note that a capacitor is connected to the 24 VDC supply. To prevent excessive conducted emissions from a DC power source (typically 24 V) used for digital I/O, a 1000 picofarad capacitor should be used. Connect the capacitor from the +24 VDC to COMMON at the distribution terminals Inside a control cabinet, connect the shields of shielded cables at the MMC. The figure below illustrate shielded cable entering/leaving the cabinet.

The two different methods of terminating 

shields are used to accommodate two different immunity requirements. Immunity required inside an enclosure is considered lower because cables are typically less than three meters in length and/or can be separated from each other and from noise sources. Immunity required external to an enclosure is considered higher because the user may have less control over the noise environment. Low level signal cables that can be external to an enclosure are tested at a 2 KV level for electrical fast transients (EFTs). Low level signals that can be less than three meters in length or can be separated from noise sources are tested at a 1 KV level.
