The Pepperl+Fuchs RSD-CI-Ex8 is an 8-channel analog input module designed to interface with 2-wire transmitters or current sources located in hazardous areas. This module provides intrinsic safety by galvanically isolating input signals, ensuring secure and reliable data transmission to control systems in safe areas. It is suitable for installation in Zone 1, Zone 2, or Zone 22 hazardous locations and supports hot-swapping, allowing modules to be exchanged under voltage in Zone 1 without compromising safety. The RSD-CI-Ex8 is compatible with the IS-RPI (Intrinsically Safe Remote Process Interface) system, facilitating seamless integration into existing industrial automation setups.

Key Features:

• Intrinsic Safety: Galvanic isolation ensures safe operation of up to eight 2-wire transmitters or current sources in hazardous areas.
