Product Description

The 1769-OF4VI is a 4-channel individually isolated analog voltage output module for Allen-Bradley CompactLogix and MicroLogix 1500 systems. Each channel is fully isolated from the others and the backplane, eliminating ground loops and signal crosstalk. It delivers high-precision voltage outputs for drives, valves, and other actuators in sensitive industrial environments.

Key Notes

  • Individually isolated channels prevent ground loops and electrical interference

  • No field calibration required; hardware is factory-calibrated for life

  • Configurable per channel: mix different voltage ranges on the same module

  • Voltage outputs only; for 4–20 mA signals, use 1769-OF4CI

  • Powered by 1769 backplane; ensure sufficient 24V DC supply capacity
