Here is an introduction to the Allen-Bradley 1715-OF8I:

Overview

The Allen-Bradley 1715-OF8I is an analog output module that is part of the Allen-Bradley redundant I/O system. Manufactured by Allen-Bradley, a division of Rockwell Automation, this module is designed for use in industrial automation applications requiring precise and reliable analog output signals.

Key Features

1. Eight Isolated Analog Output Channels:

   • The 1715-OF8I provides eight independently isolated analog output channels, each capable of delivering a 4-20 mA output current. This makes it suitable for driving a variety of regulating devices such as control valves, dampers, louvers, positioners, and variable frequency drives (VFDs).

2. Redundant I/O System Compatibility:

   • As part of the Allen-Bradley redundant I/O system, the 1715-OF8I is designed to work in conjunction with other modules and components to provide high availability and fault tolerance in critical processes.

3. Modular Design:

   • The module has a modular design, requiring the use of separate termination modules and base modules (such as the 1715-A310 base module and either the 1715-TASOF8 or 1715-TADOF8 termination modules) for installation and connection.

4. LED Status Indicators:

   • The 1715-OF8I features LED status indicators for normal, ready, and run conditions, as well as individual channel LED indicators to describe the powered state of each channel.

5. Technical Specifications:

   • The module has a working voltage range of 18-32 VDC, a backplane current consumption of 260 mA, and a maximum power consumption of 3.6 W. It also has a field loop power consumption of 0.64 W and a signal current range of 4-20 mA.

6. Isolation and Protection:

   • The module offers 50 volts of continuous isolation between I/O ports, providing additional protection and ensuring the integrity of the signals.
