Excellent PLC
Product Introduction
The Allen-Bradley 1794-IV16 FLEX I/O Digital Source Input Module is a compact and efficient discrete input module designed for reliable signal acquisition in industrial automation systems. As part of the FLEX I/O platform from Rockwell Automation, this module is optimized for distributed I/O architectures requiring stable and cost-effective digital input processing.
The 1794-IV16 features 16 sourcing (PNP) input points operating at a nominal 24 VDC, making it suitable for use with sinking field devices. Its non-isolated design allows for simplified system configuration and reduced cost in applications where isolation is not required. Integrated LED indicators provide clear visual feedback for each input channel, improving troubleshooting and system diagnostics.
With its open-style construction and DIN rail mounting, the module ensures easy installation and dependable operation in industrial control panels.
