The Allen-Bradley 1794-IB16D is a FLEX I/O diagnostic input module with 16 sinking 24V DC inputs (10…31.2V DC on-state) that detects and reports open or shorted field wiring. It mounts on a 1794-TB32 or 1794-TB32S terminal base. FLEX I/O modules plug into a terminal base unit that carries the field wiring, so a module can be removed and inserted under power without disturbing field wiring; one FLEX I/O adapter communicates with up to eight I/O modules.
