Material Composition: Module housing: Flame‑retardant reinforced engineering plastic Internal main‑board: High‑reliability industrial‑grade FR‑4 circuit board Connector: Gold‑plated industrial‑grade backplane connector for rack connection Internal memory chip: Industrial wide‑temperature storage chip Power‑input isolation component: High‑reliability isolation power transformer

Structural Characteristics: Standard plug‑in rack‑mount modular structure, insert into dedicated system backplane rack Front‑panel equipped with status LED indicator group for power, running, fault and communication status Backplane gold‑plated connector realizes power supply, bus communication and signal interconnection Internal three independent parallel computing unit hardware layout, with independent voting logic circuit No moving mechanical parts inside module

Working Principle: Three independent hardware computing units receive same input signal simultaneously and execute safety‑logic operation respectively. Hardware voting circuit compares output result of three channels, adopts two‑out‑of‑three voting logic to output final safety control signal. When one computing unit generates fault output, voting circuit masks faulty channel result, system still maintains correct safety‑function output. Built‑in self‑diagnosis circuit monitors status of each hardware channel continuously. Dual isolated power‑input circuit supplies power for triple‑redundant computing unit. Communication unit completes data interaction with upper system and field I/O modules. All safety‑logic programs run inside redundant processor hardware platform.

Installation Requirements: Insert module into dedicated system rack backplane slot, lock module fixing screw. Install inside temperature‑controlled industrial control cabinet. Ensure cabinet internal ambient temperature keeps within ‑25 °C ~ +60 °C. Use dual independent 24 V DC power source for dual power‑input terminals. Separate safety‑system wiring from non‑safety‑system signal cable, maintain wiring distance to avoid electromagnetic interference. Complete protective ground connection of cabinet rack. Follow SIL‑level safety‑system installation specification for field wiring.

Usage Notes: Only use certified safety‑programming software for logic programming, forbidden arbitrary modification of internal hardware parameters. Do not operate outside permitted ambient temperature range. When single‑channel fault alarm appears, replace spare module in time, long‑term running with single‑channel fault is forbidden. Cut off rack power before plug‑unplug module unless supporting hot‑swap. Prevent conductive dust and corrosive gas from entering cabinet. Periodically execute system self‑diagnosis function check. Do not use non‑certified third‑party accessories.
