The HIMA F4106 4-Channel Door Card is a compact, safety-related I/O module engineered for use in high-integrity safety systems. Developed by HIMA, a global leader in safety automation solutions, the F4106 module is primarily deployed in critical control systems where fail-safe door monitoring and control is essential. Each unit is equipped with four independent input/output channels, enabling seamless integration with access panels, doors, and hatches on industrial cabinets and enclosures.

The module is part of HIMA’s modular hardware platform and can be integrated into HIMax or HIQuad safety systems, facilitating both centralized and distributed architectures. It enables monitoring of door status, control of solenoids, and safety interlocking—all under stringent SIL (Safety Integrity Level) standards.

Its robust design ensures continuous operation in harsh environments, including power plants, oil & gas facilities, chemical plants, and other high-risk industrial settings.

Technical Specifications

Product Applications

The HIMA F4106 is widely used in process and manufacturing industries where operator access control and safety interlocking are crucial for ensuring equipment integrity and personnel safety. Common applications include:

• Industrial Cabinet Door Monitoring: Detects open/closed door status and interlocks power or process access.

• Access Control for High-Voltage Switchgear: Prevents accidental opening under live conditions.

• Machine Guarding: Integrated into guarding systems to ensure safe access after machine stop.

• Emergency Shutdown Panels: Enables monitored access to shutdown controls.

• Hazardous Area Enclosures: Ensures access is only allowed when it’s safe.

• Railway and Transportation Equipment: Used in secure door control and monitoring applications.
