The technical data for the explosion-protected devices may be restricted by the limits specified in the test
certificates.
Electrical connections
One M20 x 1.5 cable gland for 6 to 12 mm clamping range
Second M20 x 1.5 threaded connection additionally available
Screw terminals for 0.2 to 2.5 mm² wire cross-section
Explosion protection See table Explosion protection certificates on page 12 onwards
Degree of protection IP 66/NEMA 4X
Use in safety-instrumented
systems (SIL)
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 hard-
ware fault tolerance in safety-instrumented systems up to SIL 2 (single device/
HFT = 0) and SIL 3 (redundant configuration/HFT = 1).
