Allen-Bradley 1769-OF8C SER A Output Module

The Allen-Bradley 1769-OF8C Series A is an analog output module compatible with CompactLogix and MicroLogix 1500 controllers. It provides eight single-ended current output channels, each configurable for 0-20 mA or 4-20 mA signals. The module features a 16-bit digital-to-analog converter (DAC), delivering a resolution of approximately 0.323 µA per bit, ensuring high-precision output. With a conversion rate of 5 ms for all channels and a step response time to 63% of the output in less than 2.9 ms, it supports rapid and accurate signal processing. The 1769-OF8C is equipped with overcurrent and overvoltage protection, safeguarding the module and connected devices. It requires an external 24V DC power supply and includes a removable terminal block for straightforward wiring. The module's compact design allows for easy integration into existing systems, making it ideal for applications requiring multiple current outputs, such as controlling modulating control valves, variable frequency drives (VFDs), and other final control elements.
