Why Engineers Specify This Model
- 8 Independent Voltage Channels in One Slot — Maximizes I/O density in space-constrained control panels; replaces up to four 2-channel legacy modules.
- Per-Channel Range Selection — Engineers can mix 0–10 V and ±10 V channels within the same module to serve different field devices without additional hardware.
- 16-Bit Resolution — Delivers 65,536 discrete output steps, enabling sub-millivolt precision for servo drives and proportional valve controllers.
- Seamless Studio 5000 Integration — Module profile auto-populates in the I/O tree; channel scaling, fault states, and hold-last-state behavior are all configured in software without DIP switches.
- Configurable Fault & Program Mode Behavior — Each channel independently configured to hold last value, ramp to zero, or output a user-defined safe state on controller fault or program mode — critical for process safety.
- No External Field Power Required — Simplifies panel wiring; all output power sourced from the 1769 backplane, reducing terminal block count and potential wiring errors.
- Proven Platform Longevity — The 1769 Compact I/O platform has a multi-decade installed base with Rockwell Automation’s committed long-term support, protecting capital investment.

Application-Specific FAQ
Q: Can the 1769-OF8V drive a 4–20 mA current loop device directly?
A: No. The 1769-OF8V is a voltage output module only (0–10 V or ±10 V DC). For 4–20 mA current output, specify the 1769-OF8C (current output variant) or use an external V-to-I converter.
Q: How many 1769-OF8V modules can I add to a single CompactLogix system?
A: The 1769 Compact I/O bus supports up to 30 modules per local bank (controller-dependent). Consult your controller’s user manual for the maximum I/O module count and backplane current budget.
Q: What happens to the outputs if the controller faults or goes to Program mode?
A: Each channel is independently configurable in Studio 5000 to: (1) hold the last commanded value, (2) ramp to zero, or (3) go to a user-defined safe-state value. This is set in the module’s Output Configuration tab.
Q: Is the 1769-OF8V compatible with Studio 5000 Logix Designer v32 and later?
A: Yes. The module AOP is included in Studio 5000 v16 and later. For v32+, download the latest AOP from the Rockwell Automation PCDC to ensure full feature support.
Q: Can I use this module with a MicroLogix 1500 controller?
A: Yes, provided you use the 1769-L23 or 1769-L35 series CompactLogix, or a MicroLogix 1500 with a 1769 expansion bus adapter. Verify the specific controller’s compatibility list before ordering.
Q: Do you provide a warranty on refurbished units?
A: Yes. All refurbished 1769-OF8V modules sold by Konmask.com carry a 12-month functional warranty covering defects in materials and workmanship under normal operating conditions.
Q: Can I order a single module for emergency MRO replacement?
A: Absolutely. We supply single units with no minimum order quantity (MOQ). Contact us for expedited processing if your production line is down.
