The 1756-OF8 is a powerful Allen-Bradley ControlLogix Analog Output that is designed to offer optimal performance for various industrial applications. It is outfitted with 8 voltage-current (V/A) analog outputs and it provides short-circuit protection. The module’s output rating is either ± 10 Volts or 0 to 20 milliamps (mA) while its signal resolution across 21 milliamps or 10.4 Volts is 15-bits. Its backplane current at 24 Volts DC is 210 milliamps and 150 milliamps at 5.1 Volts DC. The 1756-OF8 circuit’s maximum power consumption is 5.8 Watts. There is also a circuit detection feature that offers an over-voltage protection rated at 24 Volts DC as well as a short-circuit protection capability that is achieved by electronically limiting the current level to 21 milliamps or less. The voltage-current settling time is 2 milliseconds and its calibration accuracy is 0.05%. Remember, this module’s calibration interval is usually 12 months (1 year).

When operational, the 1756-OF8 has a scan time of 8 milliseconds for an integer and 12 milliseconds for a floating point. Its overall module error is 0.15% (in voltage mode), and 0.3% (in current mode). This analog output also comes with an insulation voltage of 250 Volts and it uses a reinforced insulation 1350 Volts AC (VAC) tested for 2 seconds between the backplane and its output channels. It has the T4A (North America), T4 (IEC), and the T4 (ATEX), temperature codes and it is housed in an open-type enclosure. The 1756-OF8 is designed to operate at a 30G shock rate and a 2G vibration rate of 10 to 500 Hertz. Its operational temperature varies from 0 to 60 degrees Celsius. It is suitable for use in virtually all industrial applications. The Allen-Bradley analog output module offers high performance, optimal efficiency, and reliability. If users are looking for a long-lasting, yet affordable solution for all the application needs, the 1756-OF8 is a good choice.

The product code 1756-OF8 is used for an Allen-Bradley/Rockwell Automation output analog module that can be used for both voltage and current applications. The unit has 8 outputs and it features a current draw of 150 milli amps at 5.1 Volts or 210 milliamps at 24 Volts. The 1756-OF8 module comes with an open enclosure and it has an isolation voltage of 250 Volts for continuous operation. Additionally, the unit is part of ControlLogix series and it uses an R-Ladder DAC module conversion method. The 1756-OF8 module features software-controlled electronic module keying and user-defined mechanical RTB keying. The unit only needs a single slot for installation and it is compatible with removable terminal blocks or RTBs with the catalog numbers 1756-TBNH and 1756-TBSH.

Typically, the 1756-OF8 output module requires calibration every 12 months and it has a minimum module scan time of 12 milliseconds for floating point data and 8 milliseconds for integer data, because the module supports both the integer and IEEE 32-bit floating point data formats. The 1756-OF8 analog output module has a backplane power rating of 5.8 Watts. The power consumption rating of the module is also 5.8 Watts while power dissipation rating is 5.8 to 3.15 Watts. The module has a thermal dissipation rating of 16.78 BTU per hour and an overvoltage protection rating of 24 Volts DC. The unit has a settling time of less than 2 milliseconds at up to 95% of the final value with resistive loads. Additionally, the 1756-OF8 module is electronically current-limited to 21 milliamps or less for short circuit protection and it includes open circuit protection for current outputs. The 1756-OF8 module has a T4A/T4 temperature code rating and it complies with standards such as the UL, CSA, FM, CE, RCM, Ex, IECx, KC, and EAC standards.
The Allen-Bradley/Rockwell Automation 1756-OF8 voltage/current output analog module has 8 outputs for either voltage or current power and it has an output range of +/-10 Volts or 0 to 20 milliamps. The module consumes 5.8 Watts of backplane power and it includes overvoltage protection for 24 Volts DC voltage.
