DEHNpipe DPI series surge arresters for field devices are made of corrosion-resistant stainless steel and connect directly to the device terminals. Parallel-connection models offer SPD class Type 2 protection, with applications in potentially explosive atmospheres or Class 1 Div 2 environments. These units are ideally suited for installation in process environments.
IP67-rated DEHNpipe surge protectors are designed to mount directly onto a field device. The permanently attached cables connect to the terminals of the field device.
These surge protectors are ideally suited for installation in process environments (i.e., on transducers or field bus devices), 4-20 mA measuring circuits or bus systems up to 30 VDC.
