1769-IQ6XOW4 Brand New Input Relay Output Module 1769IQ6XOW4
PRODUCT DETAILS
1769-IQ6XOW4 — Compact I/O Combination Module, 6 DC Inputs / 4 Relay Outputs
The 1769-IQ6XOW4 combines six 24V DC digital inputs and four relay outputs into a single Compact I/O module slot. For machines and panels where I/O counts are modest, this avoids occupying two slots with separate input and output modules — useful when you're trying to keep a CompactLogix system physically compact or stay within a tight backplane slot budget.
The inputs handle both sourcing (PNP) and sinking (NPN) sensors, which removes the need to match sensor type to module type at the wiring stage. The four relay outputs are form C (NO + NC) contacts rated at 240V AC or 125V DC, 2 A resistive — enough to switch pilot lights, small solenoid valves, and motor starter coils directly without interposing relays in most cases.

Wiring Basics
Inputs and outputs use separate terminal groups on the removable terminal block. The six inputs share a common terminal (COM); all input sensors should reference the same 24V DC supply common. If sensors come from different power supplies with different commons, a non-isolated input module is required instead.
Each relay output has its own COM terminal, so the four outputs can switch four entirely different voltage circuits simultaneously — mixing 24V DC indicators with 120V AC solenoids on the same module is straightforward.
When a Combination Module Makes Sense
Separate input and output modules give more flexibility — more points, more options. But for the right application, a combination module is genuinely the better choice:
- Small standalone machines that need a self-contained controller without a large I/O rack
- Remote I/O drops on a distributed system where each drop handles a limited number of field devices
- Retrofit projects where an existing enclosure has room for only a small number of additional modules
- Applications where 6 inputs and 4 outputs is close to the final I/O count — no reason to buy two partially-used modules
If the application is likely to grow beyond 6 inputs or 4 outputs, separate modules with room for expansion are the more practical long-term choice.
FAQ
Q: Can the relay outputs switch 120V AC loads directly?
Yes. The contacts are rated to 240V AC at 2A resistive, so 120V AC loads are well within spec. Derate for inductive loads — motor loads follow the AC-15 derating curve.
Q: Do the inputs work with both NPN and PNP sensors?
Yes, the inputs support both sourcing (PNP) and sinking (NPN) wiring configurations. The wiring arrangement differs between the two types, so verify sensor output type before wiring.
Q: Which controllers support this module?
Any controller that accepts 1769 Compact I/O modules, including the CompactLogix L1, L2, and L3 series. Check the controller's compatibility documentation for specific firmware requirements.
Q: How does the module get addressed in the program?
Slot position on the I/O bus determines the address. Add the module to the controller's local I/O tree in Studio 5000 — input and output tags are created automatically once the catalog number is configured.
Q: Is hot-swap supported on this module?
Hot-swap capability depends on the controller type and configuration. Some CompactLogix systems support it; others require the bus to be de-energized before module removal. Check the controller's user manual before removing under power.
