I. Basic Information

Model: F3330 (F333 is the abbreviation)

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

Software: SILworX

Applications: ESD/BMS/F&G/SIS, drives solenoid valves, relays, indicator lights, etc.

II. Hardware Parameters

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

Power Consumption: 5V @ 110mA; 24V @ 180mA (excluding load)

Channels: 8 digital output (DO)

Output Signal: 24VDC, maximum 500mA per channel (12W)

Load Type: Resistive / Inductive Load (≤12W), Indicator Light (≤4W)

Isolation: Channel-to-channel / Ground Safety Isolation

Operating Temperature: -25℃ to +70℃

Size: 4TE (25mm × 203mm × 127mm)

Weight: Approximately 0.8kg

Hot Swap: Supported

III. Interfaces and Protection

Terminal: 8 DO (+), common terminal (L-), ground, screw terminals

Indicator: LED per channel (operation / fault)

Protection: Short circuit / Overcurrent / Overvoltage / Reverse polarity protection, fault-safe shutdown

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

IV. Performance and Safety

Response Time: ≤ 200μs (test signal)

Self-Diagnosis: Channel-level diagnosis (short circuit / open circuit / overload / undervoltage)

Fault Behavior: Single-channel fault does not affect other channels, system alarm and recording

Safety Mechanism: Output circuit test, safety isolation, output cut-off to safe state when faulty

V. Usage Tips

Installation: F3 rack slot, leave 20mm clearance above and below for heat dissipation, away from strong electrical interference.

Power Supply: 24VDC regulated, L+ to positive, L- to negative, FG reliably grounded.

Connection: DO terminals connect to loads (+), L- connects to loads (-), inductive loads connected in parallel with a diode (1N4007).

Configuration: SILworX adds F3330, define channel type, fault response, safety parameters.

Maintenance: Regularly check terminal tightening, LED status; software locate faulty channels; support hot swap replacement.

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