Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-IV16 is an Allen-Bradley ControlLogix digital input module providing 16 sourcing DC inputs (8 per group) for standard 12/24 V DC control signals. It installs into a 1756 chassis with a compatible removable terminal block (1756-TBNH or 1756-TBSH) and integrates with ControlLogix I/O scanning. Typical applications include discrete signal monitoring from sensors or pushbuttons in factory automation, safety interlocks, and industrial process control systems.
