HIMA F3DIO20/802 Input/Output (DIO) module

HIMA F3DIO20/802 is a compact Digital Input/Output (DIO) module specifically designed for industrial automation and safety-critical applications. It is commonly used as an expansion I/O unit within HIMA safety systems, such as HIMAX or HIMatrix controllers.

1. Core Specifications

• Model: HIMA F3DIO20/802 (also commonly labeled as F3 DIO 20/8 02)

• Channel Configuration:

  • 20 digital inputs

  • 8 digital outputs
    This configuration is suitable for handling a large number of field signals.

• Electrical Parameters:

  • Input current: Approx. 5 mA, typically used for detecting dry contact status

  • Output current: Approx. 500 mA (some documents mention up to 2 A; the exact value depends on the specific configuration)

  • Operating voltage: 24 V DC (standard industrial control voltage)

• Protection Rating: IP20
  (Relatively low protection level; usually installed inside a protected control cabinet or with additional enclosure protection)

• Temperature Range:

  • Typical operating range: –40 °C to +70 °C

  • Some sources specify –20 °C to +60 °C

2. Functions and Applications

• Safety Integrity:
  The module complies with IEC 61508 / IEC 61511 standards and is commonly used in systems requiring SIL 2 or SIL 3 safety integrity levels.

• Installation:
  DIN-rail mounting, compact design, ideal for space-constrained installations.

• Typical Applications:
  Widely used in power plants, oil and gas, chemical and pharmaceutical industries, transportation systems (such as railway signaling), and other industrial process control environments that demand high reliability.

Summary

If you need to add additional digital inputs (such as sensors or switches) or digital outputs (such as actuators or valves) to a HIMA system, the F3DIO20/802 is a proven and widely deployed solution with a strong track record in safety-critical industrial applications.
