Description of Allen Bradley 1756-OF8H Analog Output Module 1756-OF8H Controllogix Modules Arrived
 

The Allen-Bradley 1756-OF8H analog output module comes with 8 differential outputs plus a HART modem. This module, which belongs to the ControlLogix series, has a selectable voltage or current rating that ranges from -10.4336 to 10.4336 Volts and 0 to 21.2916 milliamps. Its overall output is rated at ±10 Volts or 0 to 20 milliamps while its signal resolution is 15 to 16 bits. The module also has an overall backplane power of 6.54 Watts and a voltage range of 10 to 10.4 Volts or 0 to 20 milliamps and 4 to 20 milliamps. Its thermal dissipation is rated at 16.78 BTU per hour while its power dissipation is 4.92 Watts. Unlike other analog input or output (I/O) modules, the 1756-OF8H comes with an open circuit detection feature and it has a specified circuit detection time of 0.1 milliamps or less.

 

Allen Bradley 1756-OF8H also features an isolation voltage of 50 Volts with basic insulation meticulously tested at 1500 Volts AC for 60 seconds between the backplane and output channels. Besides, the 1756-OF8H offers over-voltage protection and it has a maximum settling time of 23 milliseconds without the HART, and a maximum of 37 milliseconds with the HART. Its voltage settling time starts at 8.5 milliseconds. This module’s calibration accuracy is 0.1% (voltage) and 0.15% (current), while its standard calibration interval is approximately 12 months. With an offset drift of 200nA per degree Celsius and a total module error of 0.15% (voltage) and 0.3% (current), the 1756-OF8H analog output is appropriate for various industrial applications. It utilizes mechanical keying, but the module’s keying can also be configured electronically. Its operating temperature is 0 to 60 degrees Celsius at 5 to 95% non-condensing relative humidity. The module, which is enclosed in an open-type chassis also comes with the IEC, T4 North America, as well as the ATEX temperature codes.
