      FAQS

      • What exactly is the PW404 S1 module?
        The PW404 S1 is a standard system power supply module (Style 1 hardware revision) developed by Yokogawa for its CENTUM CS 3000 and CENTUM VP Distributed Control Systems (DCS).
      • What is the core function of the PW404 S1 module in a system?
        It is responsible for conditioning and converting the externally supplied main AC or DC input power into stable, regulated low-voltage DC power to directly energize the racked CPU modules, control units, and internal system backplanes.
      • How do technicians properly install the PW404 S1 within a control enclosure?
        The module features a slide-in physical structure. Align it with the designated power supply slot on the baseplate, push it firmly backward into position, and secure the top and bottom mounting screws.
      • What input voltage configurations does the PW404 S1 support?
        This depends on the specific suffix codes. The series typically supports standard 100-120 Vac or 220-240 Vac AC inputs, or 24 Vdc DC inputs for specific variants.
      • How do we configure the PW404 S1 for a redundant power supply setup?
        Insert two PW404 S1 modules of identical specifications into the two adjacent power slots on the same baseplate. The backplane's built-in diode-oring circuit automatically enables power paralleling and load balancing.
