Electric actuators in AC220 single-phase ac power supply, accept from DCS, PLC systems and other operator DC4 ~ 20 ma, standard signal to
control actuators for switch valve or automatic adjustment. Electronic control module USES the advanced hybrid integrated circuit, contains the complete protection function, can control or remote control, is designed to be box form, and the resin casting seal.
driver feedback quantity with high performance conductive plastic potentiometer, high precision, long life and other characteristics, can be combined with various quarter-turn regulating mechanism into a high performance, high reliability of electric control valve. So is widely used in metallurgy, power generation, petrochemicals, paper making, light industry and other industrial sectors.
main characteristics of electric actuator
1 actuators designed with servo system ( Need not to match servo amplifier) , need to access DC4 ~ 20 ma ( Or DC1 ~ 5 v) Signal and AC220V single-phase power can work. With terminal blocks, wiring is very simple and convenient.
2 actuators ─ key components of the controller, USES the advanced hybrid integrated circuit, sealed with resin casting, for cartridge shape, small volume, high reliability.
3 the amount of electric actuator drive feedback detection with high performance conductive plastic potentiometer, resolution & lt; 0. 4%.
4 have self-diagnosis function, when a failure occurs, the controller will immediately signal indicating lights.
5 with state switch selector can set off the signal, ( Valve core in the full open and full closed or self-locking condition) 。
6 with state switch selector can be set ( Positive and reverse action) 。
7 with state switch selector can be set for the input signal ( DC4 ~ 20 ma or DC1 ~ 5 v) 。
8 adjustment zero ( Starting point) And stroke ( At the end) Simple and easy.
9 when suddenly loses power, to ensure that the valve core.
10 adopt synchronous belt transmission, reliable reduces the noise.
11 electric actuators delay protection function, when the rated load, self-locking can implement status, fault occurs, immediately start protection, and can reverse the delay protection
