常阳供应EP6000
1. GENERAL
The EP 6000 Series Positioner,mounted on a pneumatic actuator,moves the actuator by receiving DC4~20mA signals from a controller.Also,the function of detecting and feeding back the actuator displacement provides accurate position in response to DC4~20mA signals.
The EP 6000 can be used with both single and double action on actuators.

3.FEATURES
①USABLE WITH SMALL AND LARGE CAPACITY ACTUATORS
By adjusting the built-in capacity control spring,the positioner can be made optimum to the given actuator.
②LOW AIR CONSUMPTION
The relay is low in air consumption and large in capacity.
③OUTPUT CHARACTERISTICS SELECTABLE
Having a cam within the feedback construction,choices other than the standard linear characteristic available.
④COMPATIBLE WITH VARIOUS FEEDBACK TYPES
Applicable to the following types by simply exchanging the cam block.
*For Linear type actuator:Feedback for Standard lever type∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙EP 6 1
*For Rotary type actuator:Feedback for Standard lever type∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙∙EP 6 2
⑤REVERSE ACTION RELAY EASILY AVAILABLE
The positive acting relay can be used as a reverse action relay when combined with a single acting actuator that requires a reverse action control.
⑥EXPLOSION PROOF STRUCTURE MARKING ON-SITE ADJUSTMENT POSSIBLE
Explosion proof construction,with the terminal and coil blocks enclosed together in one package,makes it possible to remove the positioner cover for inside inspection or span adjustment even in an explosive ambient.
⑦INTRINSICALLY SAFE CONSTRUCTION FOR A WIDE RANGE OF APPLICATIONS
The intrinsically safe construction covers terminals and clil as one package.This,combined with the adoption of the specified zener barrier,makes the unit applicable in all hazardous gas location(including Class 0 zone)ranging from low(-40℃)to high(+60℃)temperature environment.
