Retrofit of SAIA PCD1 and PCD2 controllers

Replaces SAIA PCD1 and PCD2 controllers at the end of their service life, reusing the existing connectors directly by ribbon cable. No modification of the existing wiring, no major works, reduced shutdown time: modernisation is carried out in stages, including in buildings in operation or in sensitive areas.

Pre-production series: CE conformity assessment in progress. Availability and lead time confirmed in the quotation. For sizing, call +41 27 326 60 00.
