HDSP 2WS/24
Article number: 56 050- The 2WS/24 module can be used for protection of DC two-wire analogue or switching sensors (e.g. 4-20 mA, NO contact, NC contact). The 3WS/24 module is more suitable for protecting the input of a connected evaluating device.
- Two-stage surge protection.
- They are installed prior to the protected equipment and at the interface of LPZs 1 – 2 and higher.
- They increase the EMC level of the connected equipment against switching and atmospheric transients.
- They provide cable shield protection by limiting pulse overvoltage through a built-in 90 V gas discharge tube.
