SITOP in the SIMATIC Design
1-phase, 24 V DC (for 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 GL facilitate universal use.
■
Design
•
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
