1. ISA series electric actuator adopt HD digital LCD.
2. Phase sequence self-correcting：direction of turning setting freely, phase sequence self-correcting.
3. Default phase protection：power supply default phase and output default phase protection function.
4. Noninvasive Design： onsite  operating devices adopt non-contact sensor. No need to open cover.
5. Remote control: adjust, operate special position actuator or setting, checking data by infrared remote controller.
6. Accurate positioning： accurate monitor valve position by digital sensor.
7. Control mode：Normal remote control signal adopt 4-20mA analog quantity signal control，supply 4-20mA signal feedback（can special order）. Remote control signal and feedback signal are electric isolation with interior.
8. Signal  free configuration：Output 6 route at most connect signal for user selecting. Can free define each route signal.
9. Self diagnosis：powerful fault self diagnosis function process fault in time easily. 
10. Bus-technology：Profibus.Modbus and industrial ethernet, etc. 
11. Online remote diagnostic function.
