About 1769-OF8C
The analog module with the product code 1769-OF8C is part of the CompactLogix I/O series and it is used for output application purposes. The 1769-OF8C output module is part of CompactLogix Series A and it has a maximum current draw of 145 milliamps. In addition to that, the maximum current draw at 24 Volts DC is 125 to 160 milliamps. The 1769-OF8C analog output module operates on 0 to 20 milliamps or 4 to 20 milliamps of current range and it features a full-scale analog current range of 0 to 21 milliamps or 3.2 to 21 milliamps. The 1769-OF8C analog output module has 8 outputs that are single-ended and it has 16 bits (unipolar) of digital resolution across a full range.The 1769-OF8C output module has a conversion rate of 5 milliseconds. The conversion rate refers to all the available channels. The step response of the unit is less than 2.9 milliseconds and the maximum inductive load is 0.1 mH. The resistive load on the current output is 0 to 500 Ohms with the wire resistance. The 1769-OF8C output module has an overall accuracy of +/-0.35% full scale at 25 degrees Celsius (77 degrees Fahrenheit). The module does not require field calibration and it dissipates 2.69 Watts of heat. The 1769-OF8C module has maximum short-circuit current of 21 milliamps and it comes with protective features like overvoltage protection and open and short-circuit protection. In addition to that, the 1769-OF8C module needs about 5 milliseconds to detect open-wire conditions. The module is equipped with an “OK” indicator for the module status and it has channel diagnostics features.
The Allen-Bradley 1769-OF8C Compact Current Output Analog Module, as its name implies, can be used for providing control currents to external transducers or to actuators working in the 0 to 20 milliamps and 4 to 20 milliamps current range. It comes equipped with 8 single-ended output points that are able to work in a full-scale range starting from 0 to 21 milliamps (for the 0 to 20 milliamps current range) or starting from 3.2 to 21 milliamps (for the 4 to 20 milliamps current range). The bus current draw of the Allen-Bradley 1769-OF8C Compact Current Output Analog Module varies between 145 milliamps when it is connected to 5 Volts DC power supplies and 185 milliamps when it is connected to 24 Volts DC power supplies.
The resistive load in the current output of the Allen-Bradley 1769-OF8C Compact Current Output Analog Module ranges between 0 and 500 Ohms (including the resistance of the connecting wires). Each of the analog current output terminals is labelled, starting at Iout0+ and running all the way to Iout7+. Apart from these terminals, there are 8 terminals labelled as “ANLGCom” terminals for the common connections to ground and the 2 screw terminals from the power source. The weight of the Allen-Bradley 1769-OF8C Compact Current Output Analog Module is approximately 281 grams (0.62 pounds) and its dimensions are 118 x 35 x 87 millimeters (4.65 x 1.38 x 3.43 inches). The module can be installed using DIN rails or mounted directly on the panel. Only properly trained personnel should be in charge of the mounting, commissioning, and troubleshooting of the module in order to guarantee smooth and trouble-free operation.
