Allen-Bradley 1715-OF8I | 8-Point Isolated Analog Output Module

Overview

The 1715-OF8I from Allen-Bradley is an 8-point isolated analog output module for the Redundant I/O system. It delivers eight individually isolated 4–20 mA channels for controlling devices such as valves, dampers, and VFDs.

This module requires the 1715-A310 base and a termination assembly like 1715-TASOF8 or 1715-TADOF8. It enables signal retransmission and integration with data loggers, panel meters, or single-loop controllers.

The 1715-OF8I is designed for high-criticality applications, providing reliable control from the controller level to the I/O level. Each channel has a measurement error of 0.30% + 10 µA after one year at 40°C, with minimal temperature drift of 0.01% + 0.1 µA per °C.

LED indicators on the module display the overall status, including Healthy, Ready, Run, and individual channel energization states. Its modular design simplifies maintenance while maintaining high availability.
