The 1715-OF8I analog output module from A-B Rockwell (Allen-Bradley, A division of Rockwell Automation) is part of a redundant I/O system with several key features and functions. The following is a detailed introduction to the module:

Basic information

Model: 1715-OF8I

Manufacturer: Allen-Bradley (Rockwell Automation)

Type: Analog output module

Series: 1715 series redundant I/O modules

Technical specification

Number of channels: With eight (8) independently isolated analog output channels.

Output signal: Provides 4-20 mA of output current and is suitable for driving various regulating devices such as control valves, dampers, blinds, positors and variable frequency drivers (VFDS).

Electrical characteristics:

Operating voltage: 18-32 VDC

Backplane current consumption: 260 mA

Maximum power consumption: 3.6W

Field loop power consumption: 0.64W

Accuracy and error:

The measurement error for each channel is 0.30% + 10 μA (after one year of operation at 40°C (104°F)); 0.35% + 10μA (after 5 years of operation).

The temperature drift is (0.01% + 0.1 μA) per °C.

Isolation and protection:

There is an isolation voltage of 50 volts between individual I/O ports.

Supports 22 to 16 AWG shielded wire types with 50 volts continuous isolation voltage.

Design and installation

Modular design: The module requires the use of a 1715-A310 module base and a 1715-TASOF8 or 1715-TADOF8 terminating base.

LED Status indicator: Includes normal, ready, and operational status, as well as individual channel LED indicators that describe the power status of each channel.

Mounting type: Supports DIN rail mounting.

Environment and working conditions

Operating temperature: 13 to 158 degrees Fahrenheit (about -10 to 70 degrees Celsius).

Humidity range: 5% to 95% relative humidity (non-condensing).

Application field

The 1715-OF8I analog output module is suitable for highly critical and highly available applications from the controller level to the I/O level. It can be used not only to directly drive various regulatory devices, but also for signal retransmission for further integration or reprocessing of data loggers, panel meters and single-loop controllers.
