The housing is available in three versions:
Plastic housing for single-- and double--acting actuators
S
Metal housing for single--acting actuators
S
Explosion proof housing for single and double--acting actuators
S
The device is designed with IP66/NEMA4x degree of protection.
The intrinsically safe version can be used in hazardous areas in zone 1
or zone 2.
The explosion proof version can be used in hazardous areas in zone 1
or zone 2.
Explosion proof type "n" versions can be used in explosion hazard zone
2 areas.
The positioners (version 6DR551* for single acting actuators) are also
suitable for positioning on fittings with pneumatic actuators, which sat-
isfy the special requirements for safety devices up to SIL 2 to
IEC 61508 part 1--7 and IEC 61511 part 1--3. For this the SIL safety
instructions in the "SIL Safety Manual (PA/FF)" order number
A5E00489773 must be followed.
The positioner can be expanded with various options modules (chapter
2.6, page 31). The following modules are available in all:
I
module: Two--wire current output 4 to 20 mA for position feedback
S
y
Alarm module: three digital outputs and 1 binary input
S
SIA module: one binary output for fault messages, two binary
S
outputs for limit value alarms
Mechnical limit switch module: one binary output for the output of a
S
group error message, two switches for signalling two limit values
that can be set mechanically.
Manometer block: 2 or 3 manometers for single and double--
S
acting positioners
Connection block (NAMUR) for safety valve block
S
Mounting kits for linear and part--turn actuator
S
For decentralized installation of the positioner and position sensor:
External position detection system
S
Non-Contacting Position Sensor (NCS)
S
Only environmentally friendly materials have been used in the
construction of the positioner.
