Siemens 6ES7321-1BH02-0AA0 Digital Input Module

This 16-channel digital input module forms the backbone of reliable signal acquisition in industrial control systems. Designed for harsh environments, it handles sensor data collection in applications ranging from assembly lines to chemical processing plants.

Technical Specifications

Physical Characteristics: 40mm x 125mm x 130mm dimensions with 200g weight – compact enough for dense control cabinets. Certified to CE, UL, and cUL standards.

Real-World Applications

We’ve seen this module excel in environments like:

• Automotive production lines (switch position monitoring)
• Pharmaceutical clean rooms (sensor data acquisition)
• Steel mills (temperature sensor integration)

A recent customer in food processing noted: “The channel isolation really helped reduce cross-talk in our high-vibration environment.”

Commonly paired with S7-300 PLCs in legacy systems across oil & gas and water treatment sectors. We maintain stock of related modules like the 6ES7322-1HF01-0AA0 output module and 6ES7972-0BA00-0xA0 communication cables.
