Intelligent electric operator:

Description:

Part-turn actuators is used to drive a 90-degree angle valve butterfly valve, ball valve, 100 valves, dampers, plug valves, baffle valve.

Main Technical Performance:

  The following technical performance mainly refers to the proportion of adjustable type, on the far-controlled and the switching of the following 1,2,3,4,5,6,11,12,13,14 are not concern.

1, input signal: 4mA-20mA DC or 1V-5V DC;

  2, enter the channel resistance; 250Ω;

  3, input channel number: 1 (discrete formula 3);

 4, the basic error: ± 1, ± 2.5%;

 5, hysteresis: 1%, 1.5%;

 6, dead-0.5-3% (can be set according to system requirements);

 7, damping properties: no swing

 8, power supply voltage: single phase 220V (+10%, -15%) 50Hz ± 1%

 Three-phase 380V ± 10% 50Hz ± 1%

 9, the working environment: temperature: Integral -10 - +55 ; discrete -25 - +70 ;

 Humidity: ≤ 85%, ambient air does not contain corrosive substances;

10, shell protection grade; meet GB4208 IP65 (dust or rain);

 11, broken signal protection functions: preset There are three ways: a, in situ, b, fully open,

 c, all closed;

 12, over-current protection function: pairs of different types of models, to protect current value adjustable; (mechanical parts there have been moments Protection Switch)

 13, the dynamic electrical braking function;

 14, the ceiling and the lower limit function: at rated travel within the range of upper and lower limits adjustable

 In about 40%; (mechanical parts of a stroke control switches and mechanical limit)

 15, the working system; reversible intermittent working system, connected to sustained rate of 50% per hour connect time

 The number of 1200 times.
