ABB AX645 3BHB001914R1 Mixed Analog Input/Output I/O Module for Freelance / DCS Control Systems Core Function This compact analog I/O module is a signal acquisition and output control card for ABB Freelance distributed automation systems. It collects 4-channel analog field measurement signals (0–10V / 4–20mA) from temperature transmitters, pressure sensors, flow meters, and level transducers, converts analog signals to digital data for the main controller, and outputs 4 isolated analog control signals to regulating valves, variable drives, and actuator positioning devices. It features built-in signal filtering, channel short-circuit protection, on-board diagnostic LEDs, and RS485 Modbus RTU communication to exchange real-time process data with ABB CPU units and upper monitoring HMI panels.
