SfAR-S-6TI User Manual 4 Communication 4.1 Grounding and Shielding In most cases, I/O modules will be installed in an enclosure along with other devices, which generate electromagnetic radiation. Relays, contactors, transformers, motor controllers, etc. are examples of such devices. Radiation can induce electrical noise into both power and signal lines, as well as direct radiation into the module. - Page 10 SfAR-S-6TI User Manual Addr www.ismacontrolli.com DMP272en | 3rd Issue rev. 2 | 05/2022 page 10 of 26...
