Allen-Bradley 1715-TADOF8 1715 Redundant I/O 8-Channel Analog Output Module

Product Overview

The Allen-Bradley 1715-TADOF8 functions as a high-density analog control interface within the 1715 Redundant I/O platform. This module provides eight independent channels of 0 to 24 mA current output, specifically engineered for mission-critical applications requiring extreme uptime. We supply this unit as 100% Brand New original factory stock. It enables precise control of actuators, valves, and variable speed drives while integrating seamlessly into fault-tolerant distributed control architectures.

Technical Specifications

Engineering Advantages

• Superior Signal Integrity: The 1715-TADOF8 utilizes shielded copper wiring (Category 2) to eliminate electromagnetic interference (EMI). This shielding ensures that high-frequency noise from nearby power cables does not distort the 0–24 mA control signals, maintaining loop accuracy in electrically noisy plant environments.

• Fault-Tolerant Redundancy: As part of the 1715 series, this module supports redundant configurations. When paired with a second module, the system ensures continuous process control even if one unit fails, preventing costly emergency shutdowns in sectors like oil & gas or chemical processing.

• Optimized Thermal Footprint: The module dissipates only 3.6 W for the system logic and a mere 0.64 W per field loop. This low heat output allows for high-density cabinet mounting without the need for aggressive active cooling, even in environments approaching 85 °C.

• Flexible Field Termination: The I/O connections accommodate both solid and stranded copper wire (22–16 AWG). This versatility simplifies the field-wiring process, allowing technicians to use existing site-standard cabling without requiring specialized crimping tools.

FAQs

• Does the 1715-TADOF8 provide isolation between individual channels? No. While the module provides 50V continuous basic insulation between the I/O ports and the backplane, it does not provide isolation between individual I/O channels. Ensure your field devices share a common reference or use external isolators if necessary.

• What is the maximum current output for each channel? Each of the 8 channels supports a range from 0 to 24 mA. This extended range (above the standard 20 mA) allows for over-range signaling and specialized valve positioning requirements.

• Can I use unshielded wire for the I/O connections? We strictly recommend using shielded copper wire rated for at least 85 °C. Using unshielded cable increases the risk of signal jitter and may violate the module's Category 2 wiring compliance.

• Is this a factory-sealed unit? Yes. We guarantee this product is 100% Brand New, shipping in its original Allen-Bradley packaging with all factory seals and documentation intact.
