MODEL: MEX-C MEX-C SPECIFICATIONS ES-4615 Rev.9 Page 1/3 http://www.m-system.co.jp/ Final Control Elements VALVE POSITIONER (potentiometer feedback; external SSR drive) Functions & Features

  • Controlling an electric actuator powered with 100/ 200 V AC
  • Feedback potentiometer 100 Ω – 10 kΩ
  • Constant current output for driving external SSRs
  • Timer for motor's overheat protection
  • Re-transmitted output Typical Applications
  • Three phase AC motor
  • Loop powered isolator can be used for isolating between setpoint input signal and transmitter output signal (1.97) 136 (5.35) (3.15) mm (inch) MODEL: MEX–C–[1][2]
