HIMA F3348 Safety Module 8-Channel 48V DC Output

Product Overview

The HIMA F3348 is a high-reliability, 8-fold safety-related output module designed for demanding emergency shutdown (ESD) and safety instrumented systems (SIS). Engineered for critical industrial automation applications, this safety-grade module delivers eight individual 48 V DC output channels capable of driving resistive or inductive loads up to 500 mA with integrated safe isolation.

Certified for safety requirement classes AK 1 through AK 6, the F3348 features automated internal testing with short test signal durations (maximum 200 µs) to verify output integrity without interrupting connected process devices. Occupying a compact 4 TE rack slot width, the module has a net weight of approximately 0.40 kg (0.88 lbs) with a standard packed shipping weight of 2.00 kg (4.41 lbs).

Core Technical Advantages

• Safety-Related Architecture: Complies with requirement classes AK 1 to AK 6, ensuring reliable safety shutdown functionality in critical process control loops.
• Short-Circuit Proof Outputs: Eight independent 48 V DC / 500 mA channels equipped with short-circuit protection and safe galvanic isolation.
• Integrated Test Execution: Supports online self-test diagnostics with maximum test signal duration of 200 µs to prevent accidental actuator tripping.
• Flexible Load Compatibility: Drives resistive loads, inductive loads (up to 500 mA), and signal lamps (up to 4 W) with built-in safety shutdown protection.

Technical Specifications

Installation & Wiring Guidelines

• Rack Insertion: Insert the 4 TE module firmly into the designated safety rack slot and engage locking screws to maintain proper backplane connection.
• Power & Load Cabling: Ensure load wiring matches 48 V DC ratings and does not exceed the maximum per-channel current limit of 500 mA.
• Isolation Integrity: Maintain separation between safety-critical field lines and standard non-safety signal wiring to preserve safe isolation.
