Features:
- High-Density Digital Signal Control for 24V DC Current-Sinking Loads
- Verified Dielectric Isolation Up to 1200V AC or 1697V DC Point-to-Bus
- Seamless Integration with CompactLogix and MicroLogix 1500 Controller Systems
The Allen-Bradley 1769-OV16 functions as a 16-point DC digital output module within a 1769 Compact I/O system, delivering precise solid-state control to connected field devices. It continuously routes signal switching for 24V DC sink-type outputs across an operating voltage range of 20.4 to 26.4V DC, drawing 200 mA at 5.1V DC from the system backplane bus to power its internal logic. By providing 0.5 A continuous current per point (up to 8.0 A total module capacity at 60°C), the module ensures dependable solid-state switching for field actuators, indicator panels, solenoids, and interlock relays.
The 1769-OV16 delivers essential output interface functionality common to the CompactLogix system, serving as a critical control path component that directly governs the execution of field-level automation tasks. Modules are installed on a standard DIN rail or panel surface, attaching securely to adjacent 1769 modules via tongue-and-groove side locks and integrated bus connectors. To maintain signal integrity and system stability, each module must be placed within its designated power supply distance rating, occupying a single Compact I/O slot in local or expansion banks.
For multichannel sinking control applications, the 1769-OV16 organizes its 16 solid-state channels into a single common group connected through a removable terminal block (RTB). The sinking configuration operates by pulling current from the external load down to DC Common when an output point transitions to the ON state. To guard sensitive controller backplane electronics against field-side voltage transients and ground loops, the module incorporates robust electrical isolation tested at 1200V AC for 1 second (or 1697V DC for 1 second) and rated for a 75V DC continuous working voltage under IEC Class II reinforced isolation standards.
The 1769-OV16 Allen-Bradley Compact solid-state 24V DC sink output module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General
- Manufacturer Allen-Bradley
- Model 1769-OV16
- Condition New Original ready stock
- Product Family 1769-OG16,1769-OB32
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- High-Speed Discrete Control: Featuring a rapid response time of 0.1 ms ON delay and 1.0 ms OFF delay, this module is well-suited for high-speed automated packaging, precise material sorting, and synchronized assembly lines.
- High-Frequency Switching: Utilizing solid-state transistor logic instead of mechanical relays, it offers an extended operational life. This makes it ideal for applications requiring constant cycling, such as controlling 24V DC solenoid valves, small actuators, and interposing relays.
- Sinking Device Interfacing: Specifically designed for configurations where the field devices feature sourcing inputs. The 1769-OV16 switches the negative or common side of the DC circuit to complete the path to the ground for connected loads.
- Status and Alarm Signaling: Provides an efficient, high-density 16-channel solution to drive low-current factory floor signaling equipment, including stack lights, control panel pilot lamps, and small audible buzzers.
- Visual Status Indicators: Equipped with front-panel LED indicators that display the current ON/OFF status of each of the 16 output channels for rapid on-site troubleshooting.
- Surge Current Tolerance: Built to handle temporary inrush currents, absorbing up to 2.0 A per channel for a duration of 10 ms, which is repeatable every 2 seconds.
- Inductive Load Protection: Transistor outputs lack built-in suppression for heavy flyback voltages. Official technical guidelines specify that an external 1N4004 diode must be reverse-wired across all 24V DC inductive loads to prevent back-EMF damage to the module.
- Galvanic Isolation: Features robust optical and electrical isolation between the field-side circuits and the internal system backplane bus, verified by a dielectric test of 1200V AC or 1697V DC for 1 second.
- Operating Temperature: Approved for standard industrial operation from 0°C to 60°C (32°F to 140°F).
- Storage Environment: Can be safely stored in unpowered environments ranging from -40°C to 85°C (-40°F to 185°F).
- Humidity & Vibration: Designed for 5% to 95% non-condensing relative humidity and certified to withstand operating vibrations of up to 5 g at 10 to 500 Hz.
- Thermal Current De-rating: The current capacity depends heavily on the ambient operating temperature: At 30°C (86°F), the maximum is 1.0 A per channel with an 8.0 A module limit; at 60°C (140°F), the maximum drops to 0.5 A per channel with a 4.0 A module limit.
