【英文介绍】

The Allen-Bradley 1756-OF6CI module is the ControlLogix A Series universal isolated analog current/voltage output module. The module has 6 available independent isolated current outputs. It also has a 13-bit resolution and a current of 21 mA (2.7 μA). It requires a 1756-TBNH or 1756-TBSH detachable terminal housing (RTB) before it can be installed in a grounded and mounted case.

The types of communication formats provided by the 1756-OF6CI module are integer and floating point formats. The functions of the analog output module include data echo, ramp/rate limit, clamp/limit, clamp/limit alarm, and hold for initialization. Programming the functions of 1756-OF6CI.

It has a range of 0 to 20 mah, a low signal and user count of 0 mah and -32,768 counts, and a high signal and user count of 21.074 mah with 32,767 counts. The module has a current consumption of 250 MA at 5.1V and is terminated from 0 to 550 ohms on OUT and RTN, and 551 to 1000 ohms on OUT and ALT. At 24V, its current consumption is 225 mA (0 to 550 ohms terminated at the top of OUT and RTN) and 300 mA (551 to 1000 ohms terminated at OUT and ALT). Its total backplane power is 6.7 W (0 to 550 ohms) and 8.5 W (551 to 1000 ohms). The module has a maximum power consumption of 5.5 W (0 to 550 ohms load) and 6.1 W (551 to 1000 ohms load). It has no open circuit detection, but has 24V DC overvoltage protection and short circuit protection limited to 21 mA or less. The continuous isolation voltage is 250V for a routine test of 2 s at 1350V AC.

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. Under resistance load, its establishment time is less than 2 ms to 95% of the final value, the calibration interval is 6 months, and the calibration accuracy is better than 0.1% at 25 degrees Celsius, with 4 to 21 mA. Nominal gain drifts with temperature of 60 ppm/ C and maximum gain drifts of 100 ppm/ C/C.
