Honeywell 10101/2/1 | Fail-Safe Digital Input Module

Manufacturer: Honeywell
Product Number: 10101/2/1

The Honeywell 10101/2/1 is a high-reliability Fail-Safe Digital Input (DI) Module designed specifically for safety-critical industrial applications. 

Key Features

• Fail-Safe Design
  Engineered with a fail-safe architecture, this module defaults to a safe state in the event of a failure, preventing unsafe conditions. This makes it particularly suited for emergency shutdown (ESD) and fire and gas (F&G) systems.

• High-Level Signal Compatibility
  Designed to receive and process 24 Vdc digital signals, ensuring broad compatibility with standard industrial sensors and switches.

• Compact and Efficient Design
  Space-efficient with a form factor of 4 TE, 3 HE (4 HP, 3U), ideal for high-density installations in industrial cabinets.

• Regulatory Compliance
  Holds multiple safety and quality approvals, including CE, TUV, and UL, confirming adherence to international safety and performance standards.
