Output Architecture
Catalog Number 1756-OF4
Module Family ControlLogix Analog Output
Output Channels 4
Output Type Voltage or Current
Isolation Non-isolated between output channels
Terminal Interface 20-pin removable terminal block system
Electrical Performance
Voltage Output -10…+10 V
Current Output 0…20 mA
Voltage Resolution 15 bits across 10.5 V
Voltage Resolution / Bit Approx. 320 µV/bit
Current Resolution 16 bits across 21 mA

Control & Configuration
The 1756-OF4 can operate with integer or floating-point data formats. Floating-point operation provides access to the module's broader configuration feature set, including scaling, clamping, ramping, and rate/limit alarms. Configuration can define output behavior during program operation and communications faults.
Data Formats Integer / Floating Point
Scaling Signal-to-engineering-unit scaling
Run Mode Ramping Available in floating-point mode
Program / Fault Response Configurable output behavior
Backplane & Installation
Backplane Voltage 5.1 V DC / 24 V DC
Backplane Current 200 mA max @ 5.1 V; 155 mA max @ 24 V
Power Dissipation 4.74 W at full load
RTB Type 20-pin removable terminal block
Typical Wire Range 22…14 AWG for single-wire connection
Application Logic
01
Controller Command
Digital control data is transferred to the analog output module.
02
Scaling
Signal values can be associated with engineering-unit ranges.
03
Analog Output
The module produces a voltage or current command at the selected channel.
04
Field Device
The analog signal can control valves, drives, actuators or other devices.
CONTROLLOGIX FAMILY RELATIONSHIP
 
The 1756-OF4 belongs to the non-isolated ControlLogix analog output family. Its four-channel format is positioned between compact output requirements and higher channel-density configurations.
Model Channel Count Output Type Isolation / Construction Position in System
1756-OF4 4 Voltage / Current Non-isolated between output channels Compact 4-channel analog output
1756-OF4K 4 Voltage / Current Conformal coated version 4-channel configuration for environments requiring additional coating protection
1756-OF8 8 Voltage / Current Non-isolated between output channels Higher channel-density analog output
1756-OF8K 8 Voltage / Current Conformal coated version Higher channel-density coated configuration
1756-OF4XT 4 Voltage / Current Extended-environment version Extended operating environment, -25…70 °C
Selection distinction: The key difference is channel density and construction. The 1756-OF4 provides four channels; the 1756-OF8 doubles the available output channels in the same general non-isolated analog-output family. The “K” variants add conformal coating, while the “XT” variant addresses an extended environmental temperature range.

1756-OF4 PURCHASING FAQ
 
Q1. Can the 1756-OF4 handle both voltage and current output requirements in the same project?
Yes. The 1756-OF4 supports voltage and current output ranges, with each output channel configured for the required signal type. The supported ranges are -10…+10 V and 0…20 mA.
Q2. Is the 1756-OF4 appropriate when individual analog output channels require electrical isolation?
The 1756-OF4 is a non-isolated analog output module, and its individual output channels are not isolated from one another. Applications requiring channel-to-channel isolation should be evaluated against an isolated ControlLogix analog output model instead.
Q3. What should be checked when replacing an existing 1756-OF4 in a running ControlLogix installation?
Check the catalog number, module series, firmware compatibility, configured output ranges, scaling, program/fault output behavior, terminal-block arrangement, and the controller configuration before replacement. Matching the catalog number alone does not confirm that every configured behavior is identical.
Q4. Can the 1756-OF4 use ramping to reduce abrupt analog-command changes?
Yes. The non-isolated analog output family supports ramping functions. Run-mode ramping is available when the module uses floating-point data format, while ramp-to-program and ramp-to-fault behaviors can be configured for applicable operating conditions.
Q5. When is the 1756-OF4 a better channel-density fit than an 8-point ControlLogix analog output module?
The 1756-OF4 provides four analog output channels, so it can be a direct fit when the application needs four continuously variable commands rather than eight. Using a four-channel module can also simplify channel allocation when the control design has a smaller analog-output count.
