The mains pressure is used as a pressure setpoint, connected via an isolation amplifier from the analog output of the connection module to the pressure transmitter input of the compressor. A changeover relay (R1) switches back to the internal pressure sensor if the bus connection is faulty or the voltage at the master controller or connection module drops.\u003c\/p\u003e","brand":"WF Steuerungstechnik","offers":[{"title":"Default Title","offer_id":52782962475335,"sku":"DL247-0000917424","price":1720.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/3770\/2727\/files\/DL247-0000917424_404C19AA-F708-4F6C-9885-E216A0110743.webp?v=1768926141","url":"https:\/\/druckluft247.de\/en-eu\/products\/4502-steuerprogramm-fu-4-fur-master-modul-cn","provider":"druckluft247.de ","version":"1.0","type":"link"}
