The Allen-Bradley 1771-OFC DC Analog Output Module is a four-channel, 12-bit DAC‑based output module designed for PLC‑5 I/O backplanes. Used to drive analog field devices, it converts digital words from the PLC into four DC analog signals with 12-bit resolution. It is powered by the 1771 I/O backplane and communicates with the controller via block transfer, compatible with 1771 I/O chassis.
