1762-OF4 Analog Output Module – MicroLogix 1200
Allen‑Bradley | 4 unipolar single‑ended outputs | 12‑bit resolution
Product Overview
1762‑OF4 is a high‑precision analog output module for the MicroLogix 1200 series. It delivers four unipolar single‑ended outputs with 2.5 ms update time – ideal for real‑time control. The module supports 0‑10V DC and 4‑20 mA normal ranges, extending to 0‑10.5V and 0‑21 mA full scale. Built‑in open‑circuit and short‑circuit protection ensure reliable operation in demanding industrial environments.

Installation & Commissioning
- Directly mount on MicroLogix 1200 base unit – no external power supply needed.
- Use shielded twisted‑pair cables for analog signals to minimise noise.
- Set DIP switches for output type (voltage/current) before power‑up.
- Auto‑calibration routine simplifies initial commissioning.
Maintenance & Diagnostics
- Built‑in diagnostics – LED reports power and internal fault status.
- Read back channel status via ladder logic (open‑circuit / short‑circuit detection).
- Hot‑swap compatible – no need to power down for module replacement.
Compatibility
- Designed for Allen‑Bradley MicroLogix 1200 controllers (1762‑Lxx series).
- Fully compatible with RSLogix 500 and Connected Components Workbench.
- Also works with Modicon Quantum when used with appropriate adapters (not direct).
Certifications
- CE, cULus, ATEX (Zone 2), C‑Tick
- RoHS compliant, REACH
