Compatible Replacement & Equivalent Models
The following models are commonly evaluated as direct or functional replacements for the 1762-OW16. Always verify electrical ratings, bus compatibility, and firmware requirements before substitution.
- 1762-OW8 — Allen-Bradley 8-point relay output; half the I/O count, same bus; use when fewer outputs are needed
- 1762-OB16 — Allen-Bradley 16-point transistor (NPN) output; faster switching, DC loads only; not a drop-in relay replacement
- 1762-OB8 — Allen-Bradley 8-point transistor output; DC loads, compact footprint
- 1762-OA8 — Allen-Bradley 8-point triac (AC) output; suitable for AC-only loads without relay wear
- 1769-OW16 — CompactLogix platform relay output; functionally similar but requires CompactLogix controller — not bus-compatible with MicroLogix 1762
- Third-party equivalents — Some OEM-compatible modules exist; confirm I/O bus pinout, backplane current draw, and RSLogix 500 device profile compatibility before use
Why Choose the Original 1762-OW16
- Guaranteed bus compatibility — Native 1762 I/O bus; plug-and-play with MicroLogix 1100/1400 without additional configuration

- Not Compatible With: MicroLogix 1000, 1200, SLC 500, CompactLogix, ControlLogix platforms
Selection Guide
Use the following criteria to confirm the 1762-OW16 is the right module for your application:
- Load type: Relay outputs support both AC and DC loads — ideal for mixed-voltage panels
- Output count: 16 points covers most mid-size control panels; consider 1762-OW8 for smaller I/O budgets
- Switching frequency: Relay contacts are suited for low-to-medium cycle rates (<1 Hz continuous); for high-speed switching, consider transistor output modules (1762-OB16)
- Load current: Confirm each output load does not exceed 2 A; derate for inductive loads and high ambient temperatures
- Isolation requirement: 1500 V AC isolation meets most industrial safety standards; verify against your panel design
- Backplane budget: 1762-OW16 draws 75 mA @ 5 V DC — calculate total system current before finalizing module count

Replacement & Compatibility FAQ
Q: Can I use the 1762-OW16 with a MicroLogix 1200?
A: No. The 1762 I/O bus is only compatible with MicroLogix 1100 and 1400 controllers. MicroLogix 1200 uses the 1762 bus but is end-of-life — verify controller firmware compatibility before use.
Q: Is the 1762-OW16 a direct replacement for the 1762-OW8?
A: Functionally yes, but the OW16 provides 16 outputs vs. 8. The wiring terminals and I/O addressing will differ — update your RSLogix 500 program accordingly.
Q: Can I mix 1762-OW16 with other 1762 I/O modules in the same system?
A: Yes. The 1762 I/O bus supports mixing of input and output modules up to the maximum module count and backplane current budget.
Q: What is the relay contact life expectancy?
A: Rockwell Automation specifies mechanical life at rated load — refer to the official 1762-OW16 installation instructions (publication 1762-IN009) for detailed relay life data.
Q: Are third-party replacement modules safe to use?
A: Third-party modules may not carry full RSLogix 500 device profile support or Rockwell warranty. Konmask recommends original Allen-Bradley parts for critical applications. Contact us to discuss options.
