The 1756-OF6CI/A module is a general-purpose isolated analog current/voltage output module designed for use in industrial control systems. This module offers 6 independent, individually-isolated current outputs, providing excellent flexibility for various applications. It features a 13-bit resolution over a 21-milliamp current range, with 2.7 µA of resolution.
To operate, the 1756-OF6CI/A requires a removable terminal block housing (RTB), either the 1756-TBNH or 1756-TBSH, which must be installed in a grounded and configured chassis. Communication formats available with the module include integer and floating point options, allowing for broad compatibility with different control systems.
Performance Specifications:
-Maximum Scan Time: The module has a maximum scan time of 10 ms for integer format and 25 ms for floating-point format.
-Accuracy: It offers a calibrated accuracy of better than 0.1% for a 4 to 21 milliamp range at 25°C.
-Settling Time: Less than 2 ms to reach 95% of the final value for resistive loads.
-Gain Drift: Nominal gain drift is 60 ppm/°C, and maximum gain drift is 100 ppm/°C.
-Calibration Interval: The module should be recalibrated every 6 months.
