I. Basic Information

Model: F332536 (i.e. F3325 Explosion-proof Configuration Version)

Brand: HIMA (Germany)

Series: HIMatrix F3 / HIMax

Type: 6-channel SIL3 Safety Analog Output Module (Ex Explosion-proof Type)

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

Software: SILworX

Applications: ESD/BMS/F&G/SIS, Controls explosion-proof field devices (such as F6221 Transmitter)

II. Hardware Parameters

Power Supply: 24VDC, -15% to +20%

Power Consumption: Approximately 15W

Channels: 6 analog output channels (AO)

Signals: 4-20mA (standard), 0-20mA (optional)

Load: Maximum 600Ω per channel

Isolation: Channel-to-channel / Ground 2kVrms, explosion-proof isolation

Operating Temperature: -25℃ to +60℃ (explosion-proof zone -20℃ to +50℃)

Dimensions: 25mm × 203mm × 127mm

Weight: Approximately 0.8kg

Hot Swap: Supported

III. Interfaces and Protection

Terminal: 6 AO channels + common terminal + explosion-proof shielded ground (screw terminals)

Indication: LED for each channel (operation / fault / explosion-proof status)

Protection: Short circuit, overcurrent, overvoltage, explosion-proof limit energy protection

Communication: Backplane bus (connects F3311/F3313/F3318 CPU)

IV. Performance and Safety

Response Time: ≤10ms

Accuracy: ±0.1% FS (25℃), ±0.2% FS (full temperature range)

Self-Diagnosis: Channel level (short circuit / open circuit / overload / explosion-proof anomaly)

Fault Behavior: Single channel fault does not affect other channels; system alarms and records; explosion-proof fault automatically limits energy

Safety Mechanism: Output circuit redundancy detection, explosion-proof isolation barrier integration, automatically switches to safe state in case of failure

V. Usage Tips

Installation: F3 rack slot, leave 20mm clearance for heat dissipation; explosion-proof zone complies with ATEX standards.

Power Supply: 24VDC regulated, FG protective ground and explosion-proof shielded ground are separately grounded.

Connection: 6 AO channels connected to explosion-proof transmitters (+), common terminal connected (-), shield layer grounded at one end; load ≤ 600Ω.

Configuration: SILworX adds F3325, defines 4-20mA, range, fault response, explosion-proof parameters.

Maintenance: Regularly check terminals / LEDs; locate faulty channels through software; 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.
