FieldQ "fully integrated"
actuator and control modules

General Overview

Description
The FieldQ package consists of an actuator with a module for
control and position feed back and forms an integrated concept
for "On/Off" valve automation.
1. Basic actuators
The basic actuator supplies the torque, required to open and
close valves and is available in various sizes (rated
47 to 1676Nm at 5.5barg or 413 to 14874 In.lb. at 80pisg).
Double acting and spring return executions are available. The
spring return execution can be equipped with multiple spring
sets to cover a pressure range from 2 to 8 barg
(30 to 120 psig).
2. Control Modules
The Control Modules contain, next to the components for
feedback switches, also all the pneumatic control components.
Its compact and robust construction incorporates basic con-
trol and feedback functionality and is suitable for indoor and
outdoor use.
1.The enclosure of the control modules are rated IP66 / NEMA
4X according IEC 60529 and are suitable for indoor and
outdoor use.
2. The QC41, QC42 and QC43 Explosion proof control
modules are suitable for use in potentially explosive at-
mospheres and are available with FM, CSA, ATEX or IECEx
approvals
3. The QC40 with AS-Interface bus communication is a
available with Non-Sparking Ex nA or Non Incendive approv-
als and is suitable for use in potentially explosive atmo-
spheres. For this QC40 ASI module FM, ATEX or
IECEx approvals are available.
4. The QC54 with Foundation Fieldbus bus communication
is a available with Non-Sparking Ex nA or Non Incendive or
Intrinsically Safe approvals and is suitable for use in
potentially explosive atmospheres. For this QC54 ASI mod-
ule FM, ATEX or IECEx approvals are available.
5. Both the weather proof and certified control modules are
available with the Fail-In-Last-Position control function for
double acting actuators and the non intrusive switch point
adjustment.
