VI. Differences from F60DIO24/1601 (Confusing Model)

F60MI2401: Mixed I/O (DI+DO+AI), suitable for analog circuits (such as liquid level, pressure)

F60DIO24/1601: Pure digital I/O (24DI+16DO), no analog input, used for pure switch scenarios (ESD, F&G)

VII. Typical Applications

SIS/ESD: Emergency shutdown system for petrochemicals, natural gas, and power (including analog interlocks)

BMS: Boiler combustion management (flame signal, temperature / pressure analog monitoring)

F&G: Fire and gas detection (gas concentration analog + flame switch quantity)

Compressor Control: Vibration, temperature analog + anti-surge switch quantity interlock
