Siemens 6ES5420-4UA13 Digital Input Modules

Siemens SIMATIC S5 Digital Input Module SM 520 Overview

The Siemens SIMATIC S5 Digital Input Module SM 520 (Order No. 6ES5420-4UA13) is a component of the SIMATIC S5 Programmable Logic Controller (PLC) system. It is used to receive digital signals from field devices and transfer these signals to the PLC's CPU for processing.

Product Detailed Description

• Function:

• Receives digital input signals (e.g., 24V DC signals) from field devices such as sensors, switches, encoders.

• Converts the logic states ("0" or "1") of these input signals into internal signals that can be processed by the PLC.

• Provides electrical isolation to protect the PLC system from interference from field signals.

• Typically features input status indicator LEDs for easy diagnostics.

• Features:

• 8 digital input channels.

• Input voltage of 24V DC.

• Typical input current of 7 mA per channel.

• Optocoupler isolation for electrical isolation.

• Short input delay times for applications requiring fast response.

• Front connector for easy wiring.

• LEDs on the front of the module indicate the status of each input channel.
