【英文介绍】

The Allen-Bradley 1756-OF6VI is a voltage loop analog output module that is part of the ControlLogix controller platform. The module occupies a single slot in the chassis, which can be installed into any available slot on the backplane. It can also be used as a local I/O module or component module for distributed I/O architectures. The 1756-OF6VI features six (6) independently isolated voltage output channels capable of generating a +/ -10 VDC output signal. The device has a 14-bit output resolution in the 21V (1.3mV) range and a 13-bit output resolution in the 10.5V + symbol bit range. The module's current consumption is 250 mA @ 5.1VDC and 175 mA @ 24VDC, while the module's total backplane power consumption is 5.5W. The 1756-OF6VI has overvoltage protection with a rated voltage of 24 VDC and electronic short circuit protection. Can the module drive rated > 1000? Load, 10 mA. For resistive loads, the module's output establishment time is < 2 ms to 95% of the final value, while the calibration accuracy is better than 0.1% of the output range. It is recommended to calibrate the module every six (6) months with a typical offset drift of 60 μV/°C, while the module error is 0.5% of the range, the maximum module scan time is 25 ms floating point, and the integer data format is 10 ms. The 1756-OF6VI comes with an internal digital-to-analog converter (DAC) circuit using the R-Ladder type. It converts data to integer mode (left-justified, 2-second complement) IEEE 32-bit floating-point type.

The 1756-OF6VI ControlLogix voltage Loop output analog module developed by Allen-Bradley is a ControlLogix chassis slotted analog output module with six independently isolated outputs. It has an optional signal range with a total output range of +/- 10.5V, a signal resolution of 14 bits and a voltage of 21V. It has a backplane consumption of 175mA at 24V DC and 250mA at 5.1V DC, with a maximum backplane power of 5.5W. The 1756-OF6VI has a heat dissipation of 16.54 BTU/hr, a power consumption of 4.85W, and an output impedance of 1 Ω. It does not have open circuit detection, but provides 24V DC overvoltage protection and electronic current limiting short circuit protection.

The 1756-OF6VI has a 10mA load drive capability and <2ms setup time. The calibration accuracy of the 1756-OF6VI is much better than 0.1% of its range and requires recalibration only after 6 months.
