F8623B (HIMA Safety Output Module) Basic Information

Model: F8623B

Brand: HIMA (Germany's HIMA)

Type: H41q/H51q System 4-Channel Secure Digital Output Module

Safety Level: IEC 61508 SIL3, TÜV Certified

Part Number: 984862360

Installation: Rack slot type (occupies 1 slot)

Protection Level: IP20

Weight: Approximately 0.1kg

Electrical parameters

Power supply: 24VDC (system), 5VDC (backplane)

Output channels: 4 safety digital outputs (relays / transistors optional)

Output load: 24VDC, maximum 500mA per channel, short-circuit protection

Insulation withstand voltage: Input / output to ground 500V AC / 1 minute

Built-in protection: Overvoltage, undervoltage, reverse connection, overtemperature, short-circuit protection

Hardware performance

Architecture: TMR triple redundancy, independent redundant circuits per channel

Processor: 32-bit safety processor, hardware-level fault self-diagnosis

Diagnostic coverage: ≥99% (channel short-circuit, open circuit, load fault detection)

Response time: ≤10ms (safety action)

Data cache: 8MB SRAM (diagnostic / status data)

Communication interface

System bus: HIMA dedicated redundant safety backplane bus (1Gbit/s)

Protocol support: HIMA internal safety protocol, ELOP II/SILworX diagnostic protocol

Redundancy design: Dual bus redundancy, automatic link failure switching

Environmental parameters

Operating temperature: -25℃ ~ +85℃

Storage temperature: -40℃ ~ +85℃

Relative humidity: 5%~95%, no condensation

Vibration / shock: Compliant with IEC 60068 industrial standard

MTBF: >1,000,000 hours Core function

Safety output control: 4 redundant outputs, driving ESD, BMS, and F&G system actuators

Full-channel diagnosis: Real-time detection of output circuit short circuits, open circuits, and abnormal loads, fault reporting

Redundant fault tolerance: A single-channel failure does not affect other channels, and the system continues to operate safely

Hot-swappable: Supports online replacement, and automatically synchronizes configuration and status after replacement

Safety interlock: Outputs automatically cut off in case of faults, in line with the "power loss safety" principle

Panel indicator lights

PWR green: Power normal, always on

RUN green: Running normal, flashing

ALM red: Hardware/Channel failure alarm

CH1~CH4 yellow: Activated by corresponding channel output, lights up

Installation and maintenance

Push the slot into the position and lock it to ensure reliable connection of the backplane contacts

Connect the 24VDC power supply and output load according to the specification, and ground the cabinet reliably

Daily inspection of indicator light status, regular tightening of terminals, and cleaning of dust

Same model direct replacement, no need to reconfigure programs and addresses
