One M20 x 1.5 cable gland for 6 to 12 mm clamping range · Second M20 x
1.5 threaded connection additionally exists · Screw terminals for 0.2 to
2.5 mm² wire cross-sections
IP 66/NEMA 4X
Observing the requirements of IEC 61508, the systematic capability of the pi-
lot 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 de-
vice/HFT = 0) and SIL 3 (redundant configuration/HFT = 1).
