EPC800 series electrical positioner and pneumatic execution agency use the signal input 4 20 mA DC to convert to the movement of the output air pressure control execution agency. The series electrical positioner can be used for single -motion type and dual -action execution agencies.
Feature
Applicable to small -capacity and large -capacity execution agencies, after using the load control spring to select the corresponding spring, can get the positioning device that is most suitable for the execution agency
Small gas consumption
The gas consumption of the amplifier is small
You can choose the output characteristics
Because there is a cam device in the feedback machine, you can choose the output characteristics other than the standard feature
The models corresponding to various feedback methods can be used for the following executive agencies as long as the cam device is replaced
* Direct stroke execution mechanism Standard EP 8 1 *
* Corner stroke execution agency standard EP 8 2 *
* Corner stroke execution agency EP 8 4 with a shaft direct connection
Easy to change to inverted amplifier single action execution agency when it needs to be controlled to control the positive amplifier, it is easy to transform into the inverse effect type amplifier resistance and explosion -proof type
Because the encapsulation of the input terminal connector and the coil part of the input terminal and the coil part of the signal (4 20 ma.)
The essential security structure has a broad scope of applicable wiring box and coils with essential security torque coil model EP82
Therefore, the use of the special Zaner safety grid combination that can make the torque coil applies to all dangerous gases, including the environmental temperature range of the use of 0 areas to 40- 60
