The Allen Bradley 1794-IC16 is a FLEX I/O digital input module designed to provide 16 sinking input channels for industrial automation systems requiring reliable 48V DC signal acquisition. It is part of the FLEX I/O platform and is commonly used in distributed control architectures where modular expansion, flexible wiring, and stable field signal monitoring are essential.
Despite its similar naming to other FLEX input modules, the 1794-IC16 is typically associated with 48V DC input applications, making it suitable for specific industrial environments where higher-voltage DC control signals are used.
