        Overview Manuals Specifications Interoperability Application Scenarios Configuration

        Features:

        • Automatic testing during operation verifies output conditions, cross-talking, and safety shutdown performance.
        • Eight safety-related channels support SIL 3 applications and provide reliable switching for loads up to 500 mA.
        • Integrated safety shutdown, safe isolation, line monitoring, and short-circuit-proof outputs enhance operational security.
        Reliable output management is essential in safety systems, and HIMA F3349 provides eight monitored channels for controlling external loads. Each channel supports resistive or inductive devices with currents up to 500 mA and can also operate lamp loads up to 10 W. Output voltage is determined by the external 24 V DC or 48 V DC supply connected through the cable plug. Compact dimensions requiring only 4 SU make installation straightforward.

        Continuous diagnostics distinguish HIMA F3349 from conventional output modules. Automatic testing occurs during normal operation without interrupting system performance. Output signal readback, line monitoring, safety shutdown verification, and cross-talking detection through the walking-bit test contribute to dependable channel supervision. The 0-signal readback operating point remains at or below 6.5 V, providing an additional level of monitoring accuracy.

        HIMA F3349 is applicable to safety-related systems requiring SIL 3 performance in accordance with IEC 61508. Safe isolation and integrated shutdown functions help maintain secure operation under abnormal conditions. Short-circuit-proof outputs further improve system reliability. Through a combination of diagnostic functions and protected output channels, HIMA F3349 supports industrial applications where availability and safety are equally important.

        The F3349 HIMA 8-Channel Safety Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Hazardous Pressure Relief: In the Safety Instrumented System (SIS) of high-pressure reactors in chemical plants, responsible for driving emergency relief valves for emergency pressure relief when process parameters exceed limits.
        • Audible and visual alarm: As the terminal drive source of the key alarm chain in rail transit or high-risk workshops, it forcibly illuminates the emergency signal lights and activates the high-decibel siren when a fault occurs.
        • Channel Allocation: The hardware board provides 8 independent safety digital output channels, each with control logic that can be independently addressed in the engineering configuration software.
        • Load Matching: Each output channel provides a maximum drive current of 500 mA under 24 VDC conditions, supporting switching between resistive, inductive, and lamp-based modes.
        • Line Monitoring: Line break and short circuit detection functions can be activated in the configuration, allowing real-time status feedback through minute monitoring current.

        Description
        HIMA F3349 is a safety-related 8-channel output module intended for applications requiring high integrity and reliable output control. Each channel can drive resistive or inductive loads up to 500 mA when supplied with 24 V DC or 48 V DC through the L+ cable plug. Lamp loads up to 10 W are also supported, providing flexibility for various field devices.

        An important characteristic of HIMA F3349 is the combination of integrated safety shutdown, safe isolation, and continuous line monitoring. The module incorporates automatic diagnostic functions during operation to maintain output reliability. Main test routines include output signal readback, verification of safety shutdown switching capability, cross-talking detection through the walking-bit test, and line monitoring. The operating point of the 0-signal readback remains at or below 6.5 V.

        Output channels are short-circuit-proof and provide a nominal output voltage of either 24 V or 48 V depending on the external L+ supply. Despite providing eight channels, HIMA F3349 requires only 4 SU of installation space. Operating consumption includes 0.15 A at 5 V DC, 200 mA at 24 V DC through the rear bus system, and 50 mA plus load at 24 V or 48 V DC supplied via the cable plug.

        Because of its SIL 3 capability according to IEC 61508, HIMA F3349 is suitable for safety-critical automation systems where dependable output control is essential. The module can be applied wherever field devices require monitored and protected switching functions. Continuous self-testing and diagnostic mechanisms help improve operational security while reducing the possibility of undetected faults during operation.
