MODEL: MEX-P MEX-P SPECIFICATIONS ES-4625 Rev.1 Page 1/3 http://www.m-system.co.jp/ Final Control Elements VALVE POSITIONER (position-preset contact input; built-in SSR) Functions & Features

  • Used for 24 - 200 V AC electric actuator position control
  • Controls the electric actuator to a pre-configured target position based on contact input
  • Position feedback via potentiometer (100 Ω - 10 kΩ unadjusted)
  • Direct motor driving with built-in SSR (with zero-cross circuit)
  • Restart control timer built-in to prevent motor overheating due to frequent on/off switching Typical Applications
  • Position damper control using sequencers without analog output (2.83) (3.15) 136 (5.35) mm (inch) MODEL: MEX-P-[1][2]

  • SSR (Solid State Relay) Composed only of semiconductor parts, SSR is free from arc discharge or chattering which is typical with electromagnetic relays. It features excellent characteristics against vibration, physical impact or other environmental conditions.
  • Zero-Cross Function SSR with zero-cross function turns on when AC power voltage is near zero, creating delay of switching when input is provided in the middle of an wave cycle, thus limiting transient switching noise voltage and rush current. Specifications are subject to change without notice.
