Intelligent Servo Controller – Shimaden EM70 Series

Features

  • High visibility of Control Motor opening display, which is shown in a bar graph (20 dots) and 7 segments.
  • Zero/Span adjustment of opening can be done automatically at the touch of a single button.
  • By means of the combination of SSR and relay, the drive unit can control directly large capacities (20-240V / 2A).
  • A wide selection of additional functions (optional) is available to suit various requirements. (Events, analog output, external operation, square root extraction, communication function)
  • Dust and splash proof front panel equivalent to IP66
Enquiry

An embedded panel servo controller with 20-dot bar graph and digital display is featured. For feedback resistance, a range from 100 Ω to 2 kΩ can be used. For output, relay contact or SSR and contact can be selected. The potentiometer has a zero-span automatic adjustment function. A 3-point external control input is a standard feature. A dustproof and drip-proof structure suitable for IP66.
