1-phase, 24 V DC (for S7-300 and ET200M) Siemens

Обзор



The design and functionality of the SIMATIC PS 307 single-phase load power supply (system and load current supply) with automatic range switchover of the input voltage is an optimal match to the SIMATIC S7-300 PLC. By means of the connecting comb that is supplied with the system and load current supply, the supply to the CPU is quickly established. It is also possible to provide a 24 V supply to other S7-300 system components, input/output circuits of the input/output modules and, if necessary, the sensors and actuators. Comprehensive certifications, such as UL, ATEX or GL facilitate universal use (does not apply to outdoor use).

Дизайн


  • The system and load current supplies are screwed directly onto the S7-300 standard mounting rail and can be mounted directly to the left of the CPU (no installation clearance required)
  • Diagnostic LED for indicating “Output voltage 24 V DC O.K."
  • ON/OFF switches (operation/stand-by) for possible swapping of modules
  • Strain-relief assembly for input voltage connection cable

Функции


  • Connection to all 1-phase 50/60 Hz networks (120 / 230 V AC) through automatic range switching (PS307) or manual switching (PS307, outdoor)
  • Short-term power failure backup
  • Output voltage 24 V DC, stabilized, short circuit-proof, open circuit-proof
  • Parallel connection of two power supplies for enhanced performance
