I. Basic Information

Model: F333138 (F3331 Explosion-proof / High Protection Edition) Brand: HIMA (German Rising Star)

Series: HIMatrix F3 / HIMax Type: 8-channel SIL3 safety digital output module (DO, open collector)

Safety level: SIL3 (IEC 61508), TÜV AK6, Cat.4/PL e, ATEX Ex ia/ib

Software: SILworX

Applications: ESD/BMS/F&G/SIS, drives explosion-proof solenoid valves, relays, indicator lights

II. Hardware Parameters

Power Supply: 24VDC (L+), 5VDC (backplane)

Power Consumption: 5V @ 130mA; 24V @ 180mA (excluding load)

Channels: 8 DO (open collector output)

Output: 24VDC, per channel 500mA (12W); indicator light ≤ 4W

Load: resistive / inductive (≤ 12W)

Isolation: channel-to-channel / ground safety isolation, explosion-proof isolation

Operating Temperature: -25℃～+70℃ (explosion-proof area -20℃～+50℃)

Size: 4TE (25mm×203mm×127mm)

Weight: approximately 1.0kg

Hot Swap: supported

III. Interfaces and Protection

Terminal: 8×DO+, common terminal L-, explosion-proof shielding ground (screw terminal)

Indicator: per channel LED (operation / fault / explosion-proof status)

Protection: short circuit / overcurrent / overvoltage / reverse polarity, explosion-proof limiting energy

Communication: backplane bus (connected to F3311/F3313/F3318 CPU)

Characteristics: line monitoring (open circuit / short circuit), output circuit test

IV. Performance and Safety

Response Time: ≤ 200μs (test signal)

Self-Diagnosis: channel level (short circuit / open circuit / overload / undervoltage / explosion-proof abnormality)

Fault Behavior: single channel fault does not affect other channels, system alarm

Safety Mechanism: output circuit test, safety isolation, fault-safe shutdown

V. Differences from F3331/F333038

F333138: open collector output, explosion-proof / high protection type (suffix 38)

F333038: source type output, explosion-proof / high protection type

F3331: ordinary open collector version, no explosion-proof reinforcement
