Allen-Bradley 1769-OV16 Compact I/O Digital Sinking Output Module

The Allen-Bradley 1769-OV16, also cataloged as the 1769-OV16 Compact I/O Digital Output Module, operates as a dedicated hardware component for solid-state discrete load switching within CompactLogix and MicroLogix 1500 systems. The unit routes 24 VDC sinking signals across 16 channels organized into a single output group, interfacing directly with field actuators, relays, and solenoids while drawing 200 mA backplane current at 5 VDC.

Hardware Specifications

Industrial Control & Drive Integration

The high-density output card leverages backplane bus communication velocity to process rapid discrete switching logic directly from the system processor. Real-time signal transfer across EtherNet/IP deterministic networks enables sub-millisecond execution times without introducing bus latencies. Continuous firmware flash compatibility checks maintain operational alignment between field load states, I/O mapping tables, and central control routines.

Frequently Asked Questions

Q: Can the 1769-OV16 output module be removed or inserted into the CompactLogix assembly while backplane power is applied?

A: No, the 1769-OV16 module does not support Removal and Insertion Under Power (RIUP). Attempting to hot-swap this module while the backplane power supply is energized causes system bus errors and risks permanent electrical damage to the connector pins.

Q: What size wiring should technicians use when connecting 24 VDC field loads to the 1769-OV16 terminal block?

A: Install solid or stranded copper wire rated for 90 deg C within the range of 22 to 14 AWG. Tighten field terminal screws securely to ensure stable contact resistance across all 16 output channels under continuous operating current limits.

Field Installation Guidelines

Mount the module on a 35 mm DIN rail or secure it to an enclosure mounting plate using the integrated retractable feet. Maintain a minimum clearance of 50 mm above and below the module to promote convection cooling and manage internal heat dissipation. Wire field loads using 22 to 14 AWG copper conductors, separating 24 VDC output lines from high-voltage AC power wiring and motor drive outputs. Connect external load supply power directly across the designated VDC and DC NEUT terminals on the removable terminal block before applying system power.
