Technical Data

Typical Applications

• Conveyor and Handling Systems: Accepts digital start/stop commands and analog speed references, ensuring precise motor operation and accurate product flow.

• Complex Industrial Machinery: Processes signals from limit switches, safety sensors, and potentiometers while providing relay feedback for fault indication and status signaling, essential for interlocking logic.

• Specialized Motion Control: Supports control programs requiring non-standard I/O mapping or advanced synchronization, such as in printing or textile machinery.

FAQ

Q1: Why does this board have a name suggesting both "I/O" and "Rectifier" functions?

A1: This board integrates both functions: it manages low-voltage control signals (I/O) while also containing or interfacing with the rectifier circuitry, which converts AC mains voltage to the DC-link voltage and supplies low-voltage DC power for control electronics.

Q2: What is the primary function of the Analog Input terminal on this board?

A2: The Analog Input (0 V to 10 VDC) typically serves as the speed reference signal, allowing an external potentiometer or PLC output to adjust motor speed steplessly.
