Allen-Bradley 1756-OF8H ControlLogix Analog Output Module – 8-Channel, HART Communication, 15-16 Bit Resolution (SER A)

Enhance the control capabilities of your industrial automation system with the Allen-Bradley 1756-OF8H Analog Output Module. As a critical component of the ControlLogix controller platform, this module provides precise, high-resolution output control necessary for complex process and manufacturing applications. This is a Series A model.

High-Resolution Analog Output

The 1756-OF8H is designed for versatility, offering multiple configurable channels to suit diverse application requirements:

Channel Count: Features Eight (8) independent output channels.
Output Types: Each channel is individually configurable for both current and voltage output signals:
- Current Output: Configurable for standard industrial ranges of 0-20 mA and 4-20 mA.
- Voltage Output: Configurable for +/-10 VDC (Volts DC).
Resolution: Delivers high precision with a resolution of 15 to 16 bits across all supported ranges, ensuring accurate and stable signal control.

Integrated HART Communication

A key feature of the 1756-OF8H is its embedded digital communication capability:

HART Modem: Includes One (1) Highway Addressable Remote Transducer (HART) modem. HART functionality allows for simultaneous digital communication alongside the standard 4-20 mA analog signal. This enables advanced diagnostics, remote calibration, and device configuration without interrupting the primary control loop.
Logix Integration: Seamlessly integrates with Allen-Bradley Logix controllers (ControlLogix), simplifying programming, configuration, and diagnostics through the common system environment.

This module is essential for applications requiring precise current or voltage outputs combined with advanced field device management.
