Working Principle: Two separate 24 VDC DC power sources feed module dual input terminals. Internal power‑OR‑ing circuit realizes seamless redundant power merging. Regulator circuit outputs stable 24 VDC power to compact Trusted rack backplane power rail. Monitoring circuit samples input voltage, output current and internal component temperature continuously. Fault condition triggers hardware protection and timestamped fault‑alarm output. Single DC input path failure cannot affect module normal DC output performance.
Material Composition & Structural Characteristics:
- Housing: Miniaturized die‑cast aluminum alloy shielding shell
- Circuit substrate: Multi‑layer FR‑4 industrial printed circuit board, integrate compact power‑processing components
- Backplane connector: Gold‑plated high‑density anti‑vibration industrial connector
- Front panel: Flame‑retardant engineering plastic with LED indicator array, IP20 protection grade
- Card‑type plug‑in structure for compact Trusted chassis power‑supply‑slot installation
Installation Requirements:
- Insert T8224 module into dedicated compact power‑supply slot of Trusted small‑form‑factor rack chassis, tighten front‑panel locking screws
- Two DC input loops connect to two independent upstream 24 VDC power supplies
- DC power cables adopt shielded twisted‑pair power cables, separate routing from high‑voltage AC power circuits
- Cabinet protective ground resistance ≤4 Ω
- Guarantee cabinet internal air convection for heat dissipation
- Total connected I/O load power shall not exceed module rated 150 W output power
Application Scenarios:
- Skid‑mount process equipment compact Trusted safety‑control rack power supply
- Small‑scale local safety‑interlock subsystem DC redundant power distribution
- Package‑unit fire‑gas safety monitoring cabinet power unit
- Petrochemical auxiliary skid safety instrumented system power source
- Space‑limited industrial container‑type safety‑control cabinet power supply
Usage Notes:
- Hot‑swap operation only permitted under dual DC input maintain valid power supply
- Module shell disassembly is forbidden; zero user‑maintainable internal parts
- Avoid reverse‑polarity DC input connection during field wiring
- After module replacement, verify dual‑input redundancy switching and full diagnostic‑function performance
- Operate strictly within rated operating temperature range
- Periodically check DC input terminal fastening torque and field‑loop load‑current parameters
