Protection: IP20

IV. Safety and Functional Features

Safety isolation: Electrical isolation between CPU and I/O to prevent fault spread

4-channel independence: Each channel can be configured independently, flexible for different signals

Full self-diagnosis: Full coverage of open circuit, short circuit, overcurrent, power/bus faults

Fault safety: DO safely disconnects during faults/loss of power, compliant with SIL3 principle

Redundancy compatibility: Supports QMR/TMR architecture, dual-machine hot standby

Programming software: SILworX/ELOP II configuration, diagnosis and testing

V. Typical Applications

SIS/ESD: Isolation of critical signals, demarcation of safety zones

BMS boiler: Safety arbitration for ignition/fuel valve/blowing signals

F&G fire gas: Isolation and interlock of flame/gas detection signals

Cross-system connection: Safety system and DCS/PLC's safety gateway

High-reliability I/O expansion: Remote/distributed I/O interface of F35/F40 controllers

VI. Identifying the Same Series (Quick Differentiation)

F4111A: 4-channel safety gate/ isolation module, "safety bridge" between CPU and I/O

F3DIO20/802: 20DI + 8DO mixed I/O, directly connected to field devices

F3422/F3423: 8-channel relay output, large-load actuators

F35: Integrated controller (CPU + I/O), core of small system
