1756-OF6CI 隔离模拟输出模块
The Allen-Bradley 1756-OF6CI module is a ControlLogix series universal isolated analog current/voltage output module. This module has 6 independent isolated current outputs available. It also has a 13-bit resolution in the 21 mA (2.7 amp) range. It requires a 1756-TBNH or 1756-TBSH detachable terminal board housing (RTB) before it can be installed into a grounded and mounted case.
The types of communication formats available with the 1756-OF6CI module are integer and floating-point formats. The analog output module includes data echo, ramp/rate limit, clamp/limit, clamp/limit alarm, and initialization hold. This program features from 1756.
It has a range of 0 to 20 mah for low signal and user counts of 0 mah and -32,768 counts, and 21.074 mah and 32,767 counts for high signal and user counts. The module has a current consumption of 250 mA at 5.1V and is terminated from 0 to 550 ohms for OUTs and RTN and from 551 to 1000 ohms for OUTs and ALTs. At 24V, its current consumption is 225 mA (0 to 550 ohms, terminated at OUTs and RTN) and 300 Ma (551 to 1000 ohms, terminated at OUTs and ALTs). The total backplane power from 0 to 550 ohms is 6.7 watts and the total backplane power from 551 to 1000 ohms is 8.5 watts. For loads from 0 to 550 ohms, the module has a maximum power consumption of 5.5 watts, and for loads from 551 to 1000 ohms, the module has a maximum power consumption of 6.1 watts. It has no open circuit detection, but has 24V DC overvoltage protection and short circuit protection limited to 21 mA or less. The conventional test lasted for 2 seconds at 1350 volts AC, with a continuous isolation voltage of 250 volts.
The 1756-OF6CI module has a maximum module scan time of 10 ms in integer format and 25 ms in floating-point format, with a module error of 0.6% of the range. For resistive loads, the establishment time is less than 2 ms, 95% of the final value is reached, the calibration interval is 6 months, the calibration accuracy is better than 0.1%, and the calibration accuracy is 4 to 21 mA at 25 degrees Celsius. The nominal gain drifts with temperature to 60 ppm Celsius, and the maximum gain drifts with temperature to 100 ppm Celsius.
