Model 1240i

Microstep Driver with Indexer

1.2A @ 40VDC output Programmable Microstepping Drive

Model 1240i - Microstep Driver with Indexer
from $313.00/ea

The 1240i is a programmable step motor driver suited for a wide range of motion control applications. It includes a sophisticated controller integrated with a 48-watt microstepping amplifier. The 1240i includes Applied Motion's easy to use Si Programmer™ Windows software for the rapid development of stand-alone motion control programs. The 1240i can also be commanded in real time from a host PC or PLC, using the Si Command Language™. For multi-axis applications, up to eight Applied Motion Si™ drives (stepper or Servo) can be networked using a single SiNet™ Hub.

The 1240i includes 8 optically isolated programmable inputs for triggering, branching, position sensing and end of travel detection. 3 optically isolated programmable outputs can send signals to other electronic devices and activate relays.
