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

Observing the requirements of IEC 61508, the systematic capability of the pilot
valve for emergency venting as a component in safety-instrumented systems is giv-
en.
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).
