The Allen-Bradley 1794-IV16 is a FLEX I/O digital input module with 16 sourcing 24V DC inputs, an on-state input voltage of 10…31.2V DC and 8 mA nominal at 24V DC. It mounts on a 1794-TB3, 1794-TB3S, 1794-TB3K or 1794-TB3SK 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.
