SIEMENS Power supplies 1-phase, 24 V DC for SIMATIC S7-1200

Overview

In terms of design and functionality, the SIMATIC PM 1207 single-phase load power supply (PM = power module) with automatic range selection of the input voltage is an optimal match to the SIMATIC S7-1200 PLC. It provides the supply to CPUs with 24 V input as well as to signal modules, and to 24 V loads connected to the modules. Comprehensive certifications, such as UL, ATEX and DNV GL enable universal use.

Design1-phase, 24 V DC for SIMATIC S7-1200

  • The load current supplies are directly fastened to the S7-1200 mounting rail (without connection to the backplane bus) and can be mounted directly to the left of the CPU (no installation clearance required)
  • LED for status indicator “24 V OK”
  • Two 24 V DC output terminals for connection of 24 V consumers

Function

  • Connection to all 1-phase networks (120 V AC/230 V AC) through automatic range switching
  • Short-term power failure backup
  • Parallel connection of two load current supplies for enhanced performance
