actuator rotary electrical input and output signal 4-20ma 400AC

Summary

The electric actuators we manufactured are the products by using the introduced advanced technology from BERNARD Company of France.

It has various kinds of protection function and control mode. It can be divided into the quarter-turn series, linear-turn series and multi- turn series. There are more than hundred kinds of specifications. Its control main board is continuously upgrading and updating and the new products appear rapidly in order to satisfy the needs of modern industrialization.

The electric actuator has already widely applied in the large and medium-sized project which is the newly built and was highly appraised by users.

At the same time, we also accumulate rich technology and scene experiences in the process of updating and upgrading DKJ or other actuators to the introduced series.

Features of the introduced series

The introduced new generation of intelligent model

Assembled and manufactured in domestic, BELL and SD series introduce the advanced technology from France and the key components are imported from the country of origin. The manufacturing process is strictly in accord with the technique requirements of French company. However, the series mentioned above is produced with higher quality and lower cost.

With the compact structure, light weight, fully function, over 1200 times per hour of the starting times and great logic control circuit, this series is especially applied to the conditions of high-efficient automation and frequent movements.

 Cut-off signal protection

The actuator stop at the original, all-on or all-off position which is instructed by users as the signal is interrupted by accident or the input signal is less than 3mA (called the cut-off signal) in order to guarantee the whole system’s safe and stable. It also possesses the output connection point for alarm.

Over-torque of two- way protecting function

The actuator has an over-torque surveying device that can accurately survey the torque of the valve. When the torque exceeds the setting scope, the torque switches inside the actuator and outputs a signal to the controlling circuit for stopping the motor to protect the valve, the driving parts and the motor. After the mechanical over-torque fault is relieved, shutting down the power supply or input an instantaneously reversed signal, the actuator will come back to turn normally.

The main technical parameters of the electric actuator 

The following technical parameters are mainly applied to the proportional modulating type electric actuator.Item1,2,3,4,5and 6 are not suitable for the remote-control type electric actuator and switch type electric actuator.

1.The input signal: 4--20mA DC

2.The input resistance: 250 ohm

3.Input passage: 1
4.Basic error: 1%, 2.5%

5.Deviation: 1.5%

6.Deadline:  0.5%--3% continuously adjustable

(according to the indication of system)

7.Damping characteristic:  No-oscillating

8.power supply: three-phase 380V~50Hz, single-phase 220V~50Hz  for selected

9.Working conditions: Temperature:  Integral-type -10°C-- +55°C, separate-type -25°C -- +70°C
