Siemens 6ES5420-8MA11 Digital Input Module

Siemens 6ES5420-8MA11 Digital Input Module

Product Details Introduction

Siemens 6ES5420-8MA11 is a digital input module used for Siemens S5 series PLC systems. Its main function is to receive digital signals from external devices and transmit these signals to the PLC for processing. The following is the detailed information of the module:

Main features:

Series: S5 Series

Model: 6ES5420-8MA11

Type: Digital Input Module

Number of input channels: typically 32 numerical input points

Input voltage: 24V DC (direct current)

Function:

Receive digital signals (on/off signals) from external sensors, switches, buttons, and other devices

Convert these signals into data that can be processed by PLC and trigger the corresponding control logic

Input type: Binary (numeric) input, usually used to monitor device status (such as button press or release, sensor detection of a certain event, etc.)

Application scenarios:

Industrial automation: suitable for application scenarios that require the collection of status signals from on-site equipment, such as start/stop buttons, limit switches, proximity sensors, etc.

Process control: In the manufacturing and processing industry, it is used to monitor the status of equipment on the production line and provide real-time feedback to the PLC system for executing corresponding operations.

Switch status monitoring: used to monitor the switch status of equipment or machines, ensuring that the system operates according to predetermined logic.

Technical parameters:

Input voltage range: 24V DC

Input signal type: digital signal (high/low, on/off)

Response time: Suitable for quick response situations

Channel isolation: Each input channel typically has electrical isolation between them to ensure the stability and safety of signal transmission

compatibility:

Applicable system: Suitable for Siemens S5 series PLC systems, such as S5-115U, S5-135U, S5-155U, etc.

Module installation: This module can be installed on the S5 series PLC rack as part of the system for signal acquisition.

matters needing attention:

Signal wiring: Ensure that the signal voltage provided by the connected external devices matches the input requirements of the module (24V DC) to avoid damage.

Signal interference: In industrial environments, preventing external electromagnetic interference (EMI) from affecting the quality and stability of input signals
