Siemens S7-1500 PLC Power Supply Module

Siemens S7-1500 PLC Power Supply Module Power supply module is a member of S7-1500 PLC system, which is divided into PS power supply module and PM power supply module. Based on the S7-1500 unified platform design, development and testing as well as the rich experience of Siemens in the field of automation, the S7-1500 power supply module, with its functions and EMC, fully meets the system requirements and matches with the S7-1500 PLC system.The PS power supply module connects to the backplane bus and specifically provides the internal system power required by the backplane bus, which can supply power for the module electronics and LED indicators. This system power supply provides power to the module electronics and LEDs.

- The bus is electrically isolated and galvanically isolated according to EN 61131-2.

- Supports firmware updates, identification data I&M0 to I&M4, configuration in RUN mode, diagnostic alarms and diagnostic interrupts.

PM power supply module provides efficient, stable, and reliable 24 V DC power supply for CPU/IM, I/O modules, PS power supplies, etc.

- Input 120V/230V AC adaptive, adaptable to power supply networks around the world.

- Input 120V/230V AC adaptable to power supply networks around the world. Input over-voltage resistance and output over-voltage protection improve system operation.

- The start-up and buffering capacity of the system enhances system stability.

- Advanced circuit design and high-quality electronic devices ensure the high reliability of the power supply.

- SELV compliance enhances the application of the S7-1500 PLC.

- Excellent EMC compatibility, fully compliant with the TIA integration test requirements for S7-1500 PLC systems.

SIMATIC PM 1507 Single-Phase

The SIMATIC PM 1507 single-phase load power supply (PM = power module) features automatic input voltage range selection. Its design and functionality are ideally suited to SIMATIC S7-1500 PLCs, as it supplies power to S7-1500 system components such as the CPU, system power supply (PS), I/O circuits for input and output modules, etc.; it can also provide 24 VDC power to sensors and actuators, if necessary.

Design

These load power supplies can be fixed directly to the S7-1500 mounting rails (not connected to the backplane bus) and can be mounted directly to the left side of the CPU (no mounting clearance required)

Status and troubleshooting display LEDs: running, fault, standby

ON/OFF switch for module replacement (run/standby)

Power connection plug with touch protection, input cable connection via cable elastic (fixed wiring possible)

Plug-in 24 V DC output terminal with reverse polarity protection for connection of 24 V loads (fixed wiring possible)

Functions

Connection to all 50/60 Hz (120 / 230 V AC) single-phase grids via automatic range switching

Short-time power buffering

Output of 24 V DC voltage limited to a maximum of 28 V DC (prevents damage to 24 V loads caused by excessive voltage)

50% “extra power” for 5 seconds per minute for short-time overloads, e.g. when switching 24 V power supplies

Two load supplies can be connected in parallel to increase performance

Overview of the SIMATIC S7-1500

Power supplies for the SIMATIC S7-1500

Used to convert AC or DC supply voltages to the required operating voltage for internal circuits

25 W or 60 W output power

Available for S7-1500 or ET 200MP

Configuration via STEP 7 V12 and higher models

APPLICATIONS

The power supply (PS) powers the internal circuits of the S7-1500 module via the backplane bus. These power supplies are used, for example, if the power supplied to the backplane bus by the CPU or interface module is not sufficient to power all connected modules or if more than one power supply segment should be implemented in the S7-1500 configuration or in the distributed configuration of the ET 200MP.

Design

The power supplies are screwed directly to the S7-1500 mounting rails and are connected to the upstream or downstream modules via U-connectors.

The front of the power supply includes:

Status and fault diagnostic display LEDs

Fault (Error), Run (RUN), Maintenance (MAINT)

The power supply also includes:

On/Off switch

Power terminals
