Product Details Supplier Info More products

Murrelektronik’s MASI68 components for AS-Interface installations with round cable connections are resistant to oil and lubricants, and can be used within industrial environments.

The units enable users to integrate PT 100 sensors into the AS-Interface installation, for measuring temperatures at decentralised locations near to the operating area.

Both two- and four-wire sensors can be connected to the expansion modules, which automatically detect which type is connected and do not require manual configuration during set-up.

This also applies to the 50 and 60Hz pre-integrated filters — which filter signal interferences — that are immediately ready for use.

Key product features

  • Meet IP68 protection requirements
  • The PT 100 sensors monitor temperatures on drive unit’s bearings to avoid damage caused by extreme temperatures
  • Temperature-related material expansions are also monitored in this way and processed in the control
