Allen-Bradley 1769-OF8V Compact I/O Analog Voltage Output Module
The Allen-Bradley 1769-OF8V is an 8-channel analog voltage output module designed for CompactLogix control systems and MicroLogix 1500 controller expansions. It provides eight single-ended output channels capable of driving analog field devices using configurable ranges including 0 to 10 VDC, 1 to 5 VDC, -10 to +10 VDC, and 0 to 5 VDC with 16-bit digital resolution.
The 1769-OF8V delivers high-density analog output control with 16-bit resolution across 8 voltage channels.
Channel Configuration and Signal Conversion
The 1769-OF8V converts 16-bit digital values from the system controller into proportional high-accuracy analog voltage signals. Each channel can be configured independently for specific voltage ranges to drive actuators, variable frequency drives, or position controllers. Built-in digital filtering and open-circuit detection help protect system stability under signal line disruptions.
Power Requirements and Physical Installation
Operating on the Compact I/O backplane bus, the module draws 145 mA at 5.1 VDC and 125 mA at 24 VDC logic power. It features an open-style chassis structure that supports direct DIN rail mounting or panel installation. Field signal conductors connect via a removable terminal block, allowing module servicing without wire disconnection.

Frequently Asked Questions
Q: Does the 1769-OF8V output module support analog current loops such as 4-20 mA?
A: No. The 1769-OF8V is strictly a voltage output module. For combined voltage and current or dedicated current loop applications, the 1769-OF8C or 1769-OF4 module should be selected.
Q: Can channels on the 1769-OF8V be individually configured for different voltage ranges?
A: Yes. Each of the eight output channels can be independently programmed via controller software for standard bipolar or unipolar ranges such as ±10 VDC or 0–10 VDC.
