The Allen-Bradley 1769-OF8C compact current analogue module contains 8 single-ended outputs each supports a voltage rating of 30 volts AC/30 volts DC with multiple output current ranges starting from 0 milliamps to 20 milliamps. The 1769-OF8C provides a resolution of 16 bits. This Allen-Bradley module converts and digitally saves analogue data current which can be employed by controllers such as the CompactLogix controller or the MicroLogix 1500 controller. The 1769-OF8C output module can be employed in several applications mainly in the industrial field. The 1769-OF8C module can be connected to a 1769-ADN DeviceNet adapter or with a 1769-AENTR Ethernet adapter. The 1769-OF8C output module offers the flexibility during the installation and mounting steps with two mounting M4 or #8 panhead screws for well-grounded panel mounting or on either EN 50 022 - 35 x 7.5 or EN 50 022 - 35 x 15 DIN rails. The 1769-OF8C output module dissipates an electrical power of 2.69 watts. The 1769-OF8C module has an OK status LED indicator which indicates that this module has power, passed internal diagnostics, and is communicating over the bus. This Allen-Bradley 1769-OF8C current analogue output module can be supplied through 1769 Compact I/O power supplies such as 1769-PA2, 1769-PB2, 1769-PA4, 1769-PB4 which are Class 2-rated power supplies except when connected to a MicroLogix 1500 base with a current consumption of 145 milliamps. The normal impedance of the 1769-OF8C module is 1 mega-ohm. This 1769-OF8C module supports shielded or twisted-pair Belden 8761 wire or equivalent wires. The Allen-Bradley 1769-OF8C output module can be connected easily to either the controller or to an adjacent I/O module before or after mounting. The data of the 1769-OF8C module can be configured as engineering parameters in milliamps or volts, percent of range, for PID, raw /proportional data for high resolution. The 1769-OF8C analogue module is intended for use in a mainly industrial environment that is clean and dry. This module weighs approximately 281 grams (0.62 pounds) while shipping. This Allen-Bradley module works properly at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).

The analog module 1769-OF8C of the CompactLogix I/O series 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. At 24 Volts DC maximum current draw 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 output module has a conversion rate of 5 milliseconds referring to all the available channels. The step response 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 including 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.
