HIMA F6205 (4-channel safety controller, old F series)

Position: 4-channel safety controller / CPU of HIMA's old F series (F3/F6 chassis) / TMR triple redundancy, SIL3 certified, for traditional rack-mounted SIS systems, gradually replaced by F60 series.

1. Model and basic information

Model: F6205

Brand/Series: HIMA Black Horse / F series (F3/F6 chassis)

Function: 4-channel safety controller (TMR CPU)

Safety level: SIL3, PL e, Cat.4, AK6; railway SIL4

Architecture: TMR triple redundancy (3 CPU paths for parallel voting)

Status:停产 / old model， some ongoing projects still in use， new projects recommend F60CPU01

Installation： Standard slots of F3/F6 chassis， 19-inch rack installation

II. Core Performance (TMR Architecture)

Processor: 3 × 32-bit CPU (TMR), clock synchronization voting

Memory: 1 MB for program / 1 MB for data (Flash/SRAM)

Channels: 4 independent safety channels, configurable DI/DO

Response time: ≤ 10 ms (deterministic)

Redundancy: Supports dual-machine hot standby (1oo2D), non-disruptive switching

Self-diagnosis: Full hardware/software self-check, fault-safe failure

III. Interfaces and Communications

Local I/O: 4 channels (configurable DI/DO, 24VDC)

Communication ports: 2 × RS-232/485 (Modbus RTU)

Internal bus: Special F-series safety bus (connects F3/F6 I/O modules)

Protocol: Compatible with DCS/PLC, supports communication with HMI

IV. Electrical and Environmental

Power supply: 24VDC (18~30V), power supply by F-series power module

Power consumption: ≤ 200 mA

Operating temperature: 0℃ ~ +60℃

Isolation: I/O and bus isolation, withstands 1500Vrms

Size/Weight: Standard F-series module / approximately 0.5 kg

V. Core Differences from F60CPU01 (New Model)

F6205 (Old F-Series): 4-channel fixed, small memory, few interfaces, TMR hard redundancy, old rack, discontinued.

F60CPU01 (F60 Series): No fixed channels (with I/O module expansion), large memory, multiple Ethernet ports, TMR + network redundancy, new rack, current mainstream.

VI. Typical Applications (Old Model Scenarios)

Traditional petrochemical/chemical ESD emergency stop system

Boiler BMS combustion management system

Oil and gas field F&G fire and gas detection system

Old plant renovation / spare parts replacement (F3/F6 rack)
