HIMA F3236 safety-related digital input/output (DIO) module

HIMA F3236 is a safety-related digital input/output (DIO) module under HIMA’s HIMatrix series, designed for integrated signal acquisition and control in industrial safety-critical systems. It combines multi-channel digital input and output functions, with core advantages in high safety integrity, flexible configuration, and harsh environment adaptability. It is a key component for building safety instrumented systems (SIS) in industries such as petrochemicals, power, and metallurgy. Below is its integrated detailed information based on official technical documents and mainstream supplier data:

1. Core Technical & Electrical Parameters

Parameter Category	Specific Details
I/O Channel Configuration	- Digital Input (DI): 16 independent isolated channels, supporting dry contact (NO/NC) and wet contact signals; compatible with 24V DC industrial sensors/switches.- Digital Output (DO): 8 independent isolated channels, supporting resistive/inductive loads; each channel has a maximum output current of 2A (24V DC), suitable for driving relays, solenoid valves, and indicator lights.- Isolation: Channel-to-channel isolation ≥1500V DC (1 minute); Module-to-backplane isolation ≥2500V DC (1 minute); suppresses ground loops and cross-interference between input/output signals.
Signal Performance	- DI response time: ≤1ms (for fast capture of emergency signals like E-stop triggers).- DI input threshold: High level ≥15V DC, low level ≤5V DC; avoids false triggers from voltage fluctuations.- DO output voltage: 24V DC (matches DI power supply, simplifying on-site wiring); output voltage drop ≤1.5V at full load (2A).
