The technical data for the explosion-protected devices may be restricted by the
limits specified in the test certificates.
Influences
Temperature ≤0.15 %/10 K
Supply air None
Effect of vibration ≤ 0.25 % up to 2000 Hz and 4 g according to IEC 770
Electromagnetic compatibility
Complying with EN 61000-6-2, EN 61000-6-3, EN 61326-1 and NAMUR
Recommendation NE 21
Electrical connections
One M20x1.5 cable gland for 6 to 12 mm clamping range
Second M20x1.5 threaded connection additionally available
Screw terminals for 0.2 to 2.5 mm² wire cross-section
Degree of protection IP 66/NEMA 4X
Use in safety-instrumented
systems (SIL)
Emergency venting at 0 mA set
point and using optional
solenoid valve
Observing the requirements of IEC 61508, the systematic capability of the pilot
valve for emergency venting as a component in safety-instrumented systems is
given.
Use is possible on observing the requirements of IEC 61511 and the required
hardware fault tolerance in safety-instrumented systems up to SIL 2 (single device/
HFT = 0) and SIL 3 (redundant configuration/HFT = 1).
