Digital Output Module | Allen-Bradley 1769-OV16
The Allen-Bradley 1769-OV16 is a 16-point solid-state DC sinking output module designed for use within CompactLogix systems and MicroLogix 1500 controller expansions. Operating at a nominal system supply of 24 VDC (with an operational voltage range of 20.4 to 26.4 VDC), it controls field loads by switching the negative side of the DC circuit to ground.
Sinking Output Circuit and Performance
Featuring 16 solid-state channels configured for current sinking (NPN) switching, the 1769-OV16 directs current flow from connected field loads through the module to the DC common line. The module provides fast signal execution with a maximum turn-on delay of 0.1 ms and a turn-off delay of 1.0 ms. Dedicated LED status indicators located on the front panel allow maintenance personnel to quickly verify signal activation across individual channels.
System Integration and Physical Mounting
The module integrates directly into the Compact I/O backplane bus without requiring a dedicated rack chassis, drawing up to 200 mA at 5.1 VDC logic power. It supports flexible installation on standard DIN rails or panel surfaces within control enclosures. Field connections are made via a removable terminal block, allowing module replacement without disturbing field wiring.

Frequently Asked Questions
Q: What is the functional difference between a current sinking module like the 1769-OV16 and a sourcing output module?
A: A sinking output module (1769-OV16) acts as a switch to the DC common line (negative reference), so the connected load must be wired to positive DC power. A sourcing module (such as the 1769-OB16) switches the positive 24 VDC supply directly to the load.
Q: Can the 1769-OV16 be installed in both CompactLogix and MicroLogix controller systems?
A: Yes, 1769 Compact I/O modules are natively supported in CompactLogix controller banks as well as expansion I/O banks connected to MicroLogix 1500 processors.
