F3330
HIMA
Products information
The HIMA F3330 is an 8-fold safety-related output module designed for use in industrial safety-
critical systems, compliant with TUV and CE certifications. It is engineered to control resistive or
inductive loads up to 500 mA (12 W) and lamp loads up to 4 W, with integrated safety shutdown
functionality and safe isolation to ensure reliable operation in high-risk environments.
This module is a key component in safety instrumented systems (SIS) and distributed control systems
(DCS), suitable for applications such as process shutdown, emergency stop circuits, and critical load
control in industries like oil & gas, chemical processing, and power generation. It features automatic
in-operation testing (including output signal readback and walking-bit testing) to detect faults in real
time, minimizing the risk of undetected failures.
The F3330 supports flexible wiring configurations, with compatible cables (e.g., LiYY 8×0.5 mm², LiYY
16×0.5 mm²) and flat pin plugs (2.8×0.8 mm²), and can be paralleled without external diodes for
expanded load capacity. It also includes specific component requirements for inductive loads (e.g.,
1N4007 or 1N4448 diodes) and legacy capacitor requirements (0.1 µF for releases up to AS01),
ensuring compatibility with diverse load types and system setups.
