Allen Bradley 1756-OF8H/A Analog Output Module

The 1756-OF8H/A is designed for use within the ControlLogix system, providing high-precision analog output capabilities for various industrial automation applications.

This module features 8 analog output channels, supporting HART communication for enhanced interaction with smart field devices. It allows for accurate signal output, making it ideal for controlling actuators, valves, and other analog-driven equipment. The 1756-OF8H/A integrates seamlessly with other ControlLogix components, ensuring reliable and efficient system performance. Its robust design ensures long-term durability, providing consistent operation even in demanding industrial environments.

The 1756-OF8H ControlLogix Voltage/Current Analog Output Module by Allen-Bradley is an analog output module that has 8 voltage or current outputs with a single HART modem per module. It has a selectable voltage/current signal range of -10.4336-10.4336V and 0-21.2916mA. The 1756-OF8H has an overall output rating of +/- 10V or 0-20mA and a signal resolution of 15-16 bits for all ranges. It also has a backplane current draw of 230 mA @ 5.1 VDC and 230 mA @ 24 VDC, total backplane power of 6.54W. It has a thermal dissipation of 16.78 BTU/hr, and a power dissipation of 4.92W. The 1756-OF8H has an isolation voltage of 50V with basic insulation tested at 1500V AC for 60s between output channels and the backplane. The 1756-OF8H, unlike other Analog I/O modules, offers Open Circuit Detection and has a circuit detection time at a value that must be set below 0.1 mA. Its current settling time without HART is just below 23ms, and below 37ms with HART and its voltage settling time is 8.5ms to 95% with resistive loads. It has a calibration accuracy (without HART) of 0.1% (voltage) and 0.15% (current) and its standard calibration interval is about 12 months. The 1756-OF8H has an offset drift of 100 V/deg C. or 200nA/deg. C and the module has an overall module error of 0.15% (voltage) or 0.3% (current). It has a T4 North America, ATEX, and IEC temperature code, and has an open-style enclosure rating. The 1756-OF8H’s operational temperature ranges between 0 deg. C and 60 deg. C at 5-95% non-condensing relative humidity.
