I. Basic Information

Model: F333038 (F3330 Explosion-proof / High Protection Version)

Brand: HIMA (Germany)

Series: HIMatrix F3 / HIMax

Type: 8-channel SIL3 safety digital output module (DO)

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 @ 110mA; 24V @ 180mA (excluding load)

Channels: 8 DO

Output: 24VDC, per channel 500mA (12W); indicator ≤ 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 0.8kg

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

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

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. Usage Tips

Installation: F3 rack, leave 20mm space for heat dissipation; explosion-proof area complies with ATEX.

Power Supply: 24VDC regulated, FG and explosion-proof shielding ground separated.

Connection: DO + connected to load +, L - connected to load -; for inductive loads, connect a diode (1N4007) in parallel.

Configuration: SILworX adds F3330, define channels, fault response, explosion-proof parameters.

Maintenance: Check terminals / LEDs; locate faults by software; support hot swap.

Compatibility: Compatible with F3311/F3313/F3318 CPU and F32xx DI; configuration needs to be updated when replacing.
