Technical Specifications Rated Input:120 VAC‑VDC AC Input Range:85 VAC‑140 VAC, 47‑63 Hz DC Input Range:95 VDC‑180 VDC Continuous Output Power:175 W Output Voltage:6.5 VDC Maximum Output Current:27 A Fuse:5 A time‑delay fuse Minimum Hold‑up Time:20 ms Compatible Chassis: main chassis, expansion chassis, remote RXM chassis Operating Temperature:0℃ to +60℃
Functional Features Mixed AC‑DC wide‑range input compatibility. Multi‑point internal fault monitoring circuit. Front‑panel LED indicators for PASS, FAULT, ALARM, TEMP, BAT‑LOW status. Integrated over‑current and over‑temperature protection mechanism. Supports parallel redundant power supply configuration for safety rack. External fault relay alarm contact output.
Application Scenarios Power supply for Triconex Tricon main safety control rack. Power feeding for expansion I‑O chassis. Power supply for remote RXM expansion chassis. Fault‑tolerant SIS control system in petrochemical and power station industry.
Performance Parameters Output voltage accuracy maintains ±1% across full operating condition. Complete short‑circuit, overload and over‑temperature protection performance. Fault relay contact outputs alarm signal once abnormal state detected.
Material Composition High‑power switching power supply printed circuit board. Metal heat‑dissipating housing structure. Industrial high‑current time‑delay fuse. EMI anti‑interference filter components.
Structural Features Rack‑mount plug‑in power module form factor. Front‑panel layout for status LED and alarm signal terminals. Rear side connector directly connects to system backplane bus. Passive built‑in heat dissipation structure.
Working Principle Switching power conversion circuit transforms input AC or DC power into stable low‑voltage DC power required by system backplane. On‑board circuit continuously monitors output voltage level, internal temperature and hardware fault condition. Alarm signal triggers immediately when abnormal working status appears.
Installation Requirements Install PS8310 module into dedicated power supply slot inside Triconex rack. Wire input power strictly following terminal marking instruction. Redundant dual power supply configuration is mandatory for safety‑critical racks. Maintain cabinet ventilation condition for module heat dissipation.
Usage Notes Replace blown fuse only with specified time‑delay fuse specification. Inspect alarm indicator status during regular maintenance cycle. Module housing shall not be opened under any circumstance. Verify input power voltage matches module rated range before power‑on operation.
