The HIMA F6208 does not have this standard model in the official manual. It is only commonly referred to as the F62 series analog input module (AI) and is often grouped with the F6217/F6220. It belongs to the old HIMax/F62 rack-based SIS system's safety I/O, with SIL3 certification and has been gradually discontinued.

1. Position and Model Identification

Series: F62 (HIMax) Rack-based SIS

Type: Analog Input Module (AI), presumed to be 8 channels

Alternative Models: F6217 (8-channel AI, mainstream), F6220 (new 8-channel AI)

Status: Old model /， New projects use F60 series (such as F60MI2401) or F6217/F6220

II. Estimation of Core Parameters (Based on the Series F6217 Benchmark) 

Channel: 8-channel analog input

Signal: 4-20mA / 0-10V, 12-bit resolution

Safety level: SIL3, AK6, PL e/Cat.4

Isolation: Optical isolation between channels / between buses, with a withstand voltage of 1500Vrms

Power supply: 24VDC (18-32V)

Temperature: 0℃ ~ +60℃

Size: Standard F62 rack slot (4TE wide)

III. Comparison with similar models 

F6208: Older 8-channel AI module, commonly known in the market. Parameters are the same as F6217. It is no longer in production.

F6217: Mainstream 8-channel AI module, 0/4–20mA/0–5/10V, 12-bit, SIL3, in use.

F6220: New 8-channel AI module, dual-core ARM, Ethernet + RS485, SIL3, in use.

IV. Typical Applications

Old factory SIS/ESD renovation (F62 rack)

Temperature, pressure, level and other analog quantity interlocks

Boiler BMS, fire and gas F&G system

V. Replacement Suggestions

Replacement parts: Prefer F6217 (compatible with F62 rack)

New system: Select F60MI2401 (F60 mixed I/O, more versatile)
