Electrical connection
One M20 x 1.5 cable gland, for 6 to 12 mm clamping range · Second additional
threaded M20 x 1.5 hole · Screw terminals for 0.2 to 2.5 mm² wire cross-section
Degree of protection IP 66 / NEMA 4X
Implementation in
safety-related systems in
compliance with
IEC 61508/SIL
Probability of failure on demand of safety functions PFD < 2.8 x 10
–7
for a confidence
level of 95 %.
The safe failure fraction (SFF) according to Table A1 in IEC 61508-2 is greater or
equal to 0.99.
The valves are therefore suitable for implementation in safety-related systems with a
hardware fault tolerance of 1 or 2 up to and including SIL 4.
