6ES7131-4BD00-0AA0 SIEMENS Redundant Power Supply Module 12/24VDC (0.5A) 1.9A

6ES7131-4BD00-0AA0 Description

6ES7131-4BD00-0AA0 Features

• Modular & High-Density Design:​ Part of the modular ET 200S system, allowing for flexible configuration and space-efficient assembly on a DIN rail. Each channel is individually isolated.
• High Channel Count:​ Provides 4 digital input channels in a compact module width, optimizing control cabinet space.
• Wide Voltage Range:​ Each channel can be connected to either a 24 VDC standard sensor (sourcing, PNP) or a 24-48 VDC/24-230 VAC sensor/contact, offering significant flexibility for different signal sources.
• Diagnostic Capabilities:​ Each channel features a green LED for status indication (signal present). The module supports limited diagnostics, such as wire-break detection (when used with a sensor supply) and group error signaling via a red diagnostic LED.
• Fast Response Times:​ Short input delay times ensure rapid signal processing, which is critical for high-speed control applications.
• Hot-Swappable:​ Supports module replacement during operation (hot swapping) without requiring a system stop, enhancing system availability and simplifying maintenance.
• Easy Wiring:​ Uses a separate terminal module (TM) for field connection, allowing for pre-wiring and easy module replacement.

6ES7131-4BD00-0AA0 Material & Applications

• Module Construction:​ Features a robust plastic (PBT) housing with an integrated front connector and diagnostic LEDs. It is designed for mounting on a standard 35mm DIN rail.
• Internal Electronics:​ Contains high-quality opto-isolators for each channel, providing electrical isolation between the field side and the system side for noise immunity and protection.
• Protection Rating:​ Designed for installation inside a control cabinet (IP20 equivalent), protecting it from dust and incidental contact. The field connections on the terminal module are typically IP20 as well.
• Primary Applications:​ Used in a vast array of automation systems for reading the state of standard two-wire field devices:
  • Machine Control:​ Reading inputs from pushbuttons, selector switches, emergency stops (non-safety), and door limit switches.
  • Process Automation:​ Monitoring the status of valves (open/close), pumps (run/stop), and level switches.
  • Material Handling:​ Detecting the presence of objects via photoelectric or inductive proximity sensors on conveyors.
  • Packaging & Assembly:​ Reading signals from various sensors (optical, capacitive, mechanical) in automated lines.
