The Autonics AIS-42LA-B is a servo drive module with a bipolar, two-phase stepper motor and encoder. It is rated for 60 watts and is suitable for use in applications where precise speed manipulation with feedback is needed. The module is designed to accept a variety of control signals, including step and direction, CW/CCW, analog, and pulse/direction. It is also equipped with an electronic braking resistor feature for faster stopping. The AIS-42LA-B also includes an optically isolated PLC/FSI interface for easy setup and programming. The module also includes overvoltage, undervoltage, overcurrent and over temperature protection, making it a reliable and safe choice for applications such as instrumentation, automation, and printing systems.
