Model 77 and 771 I/P Transducers

Brand: Siemens Aktiengesellschaft

Free Shipping on Orders Over $500.00 CAD

Models 77 and 771 convert a DC milliampere input signal to a pneumatic output signal directly proportional to the input.

The rugged design and ability to withstand shock and vibration allow them to be installed in harsh industrial environments.
Features
  • High signal sensitivity for demanding applications
  • Simplified design ensures reliable operation
  • Rugged, NEMA construction, with insensitivity to shock, vibration, and supply pressure variations accommodate operation in harsh environments
  • Choice of output capacities provides application versatility
