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.

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
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
