About SIEMENS PLC MODULES 6ES7322-1HF01-0AA0

Siemens 6ES7322-1HF01-0AA0 Digital Input Module

Product Type: Digital Input Module
Series: SIMATIC S7-300
Brand: Siemens

The Siemens 6ES7322-1HF01-0AA0 is a digital input module designed for the SIMATIC S7-300 PLC system. It receives digital (ON/OFF) signals from field devices such as sensors, switches, and pushbuttons, converting them into data the PLC can process.

Key Features:

• 16 Digital Input Channels: Supports binary input signals.

• Operating Voltage: 24V DC standard for industrial applications.

• Fast Response Time: Suitable for high-speed digital signal detection.

• LED Indicators: Individual LEDs for each channel to monitor input status.

• Wide Voltage Range: Ensures compatibility with multiple field devices.

• Modular Design: Fully compatible with the S7-300 modular PLC system.

• Diagnostics: Built-in diagnostics for fault detection and easy troubleshooting.

• Configuration: Easily configured using Siemens STEP 7 software.
