The 1756-OF8H is an analog output module manufactured by AB Rockwell (Allen-Bradley) as part of the ControlLogix platform. Here are some of the key features and applications of the module:
Analog output channels: The 1756-OF8 module is equipped with eight (8) analog output channels that can be configured for +/-10VDC and 0-20 mA analog output signals.
High resolution: 15-bit resolution in the 21 mA to 650 nA/bit range, and 15-bit resolution in the 10.4V to 320 µV/bit range.
Protection function: The module has the functions of open circuit, short circuit and overvoltage protection.
Conversion method: Use R-Ladder DAC, monotonic and lose-free module conversion method, and provide register data in integer mode (left-justified, 2-complement) IEEE 32-bit floating-point form.
Scanning time: The scanning time is 12 ms for floating point format and 8 ms for integer format.
Isolation voltage: The module has an isolation voltage of 250 volts and is tested for 2 seconds using 1350 volts AC between the output channel and the backplane.
Temperature codes: Available with T4A (North America), T4 (ATEX) and T4 (IEC) temperature codes in an open housing.
Operating temperature range: The module has an operating temperature range between 0 and 60 degrees Celsius and is designed to maintain its function at an impact rate of 30 grams and a vibration of 2 grams from 10 to 500 Hertz.
Offset drift: When operating, offset drift is 50 ppm/°C and 0.1 ppm/°C, and temperature-dependent gain drift is 25 ppm/°C and 50 ppm/°C (current).
Total module error: Total module error is 0.15% (voltage mode) and 0.3% (current mode).
The 1756-OF8H analog output module can be used to control and modulate electrical and field equipment, transmit or retransmit signals for interface with measuring and recording instruments or for any other purpose.
