Single-Channel Zener Barriers Series 9001

The 9001 series INTRINSPAK single-channel zener barriers enable the intrinsically safe operation of virtually all field devices. The comprehensive portfolio and the combination of zener barriers cover a wide variety of signals. The devices are incredibly robust and require little space. The back-up fuse is a convenient feature as it is standardized for all variants.

  • For the intrinsically safe operation of a wide range of devices, such as HART transmitters, solenoid valves, sensors, contacts and many more
  • Compact, space-saving devices that are easy to install on a DIN rail
  • Quick and efficient installation as barriers can be simultaneously snapped onto DIN rail and connected to ground (ISA - RPI12.06)
