I. Basic Information

Model: F3322 (often written as F332216)

Brand: HIMA (Germany)

Series: HIMatrix F3 / HIMax

Type: 16-channel SIL3 safety digital output module

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

Software: SILworX

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

II. Hardware Parameters

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

Power Consumption: Approximately 12W

Channels: 16 digital outputs (DO)

Output Voltage: 24VDC

Single Channel Current: Maximum 0.5A

Output Type: Drain / Source type, open collector or push-pull selectable

Isolation: Channel-to-channel / Ground 2kVrms

Operating Temperature: -25℃ to +60℃

Weight: Approximately 0.7kg

Hot Swap: Supported

III. Interfaces and Protection

Output: 16 DO channels + common terminal, screw terminals

Indication: LED per channel (operation / fault)

Protection: Short circuit, overcurrent, overvoltage protection per channel

Communication: Backplane bus (for communication with F3311/F3313/F3318 and other CPUs)

IV. Performance and Safety

Response Time: ≤ 5ms

Self-Diagnosis: Channel level (short circuit, open circuit, overload)

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

Safety Mechanism: Output circuit redundancy detection, output cut-off to safe state when faulty

V. Usage Tips (Installation / Wiring / Configuration)

Installation: Insert into the F3 rack backplane slot, snap lock; leave 20mm clearance for heat dissipation, away from strong electricity / frequency interference.

Power Supply: 24VDC regulated power supply, positive and negative terminals; FG protective ground reliably grounded.

Output Wiring: 16 DO channels connected to field devices (electromagnetic valve / relay coil positive pole), common terminal connected to 24VDC negative pole; single channel ≤ 0.5A.

Configuration (SILworX): Add F3322 to hardware; define channel usage, fault response; compile and download.

Maintenance: Regularly check terminals, LEDs; faults located through software; supported hot swap replacement.

Compatibility: Can be paired with F3311/F3313/F3318 CPUs and F32xx DI modules in the same rack; configuration needs to be updated when replacing.
