Introduction

Main Functions

Main system power feeding: Accept wide‑range 125‑250 VAC / 125‑250 VDC input, convert to regulated isolated DC power for UR‑series relay CPU, analog‑input modules, digital‑input/output modules and communication boards, maximum output power reaches 45 W.
Auxiliary 48 VDC power for dry‑contact inputs: Provide dedicated 48 VDC field‑side excitation power for external dry‑contact digital input loops, eliminate external auxiliary power requirement for contact‑type status signals.More products: www.plcva.com
Full galvanic isolation: High‑isolation design (2300 V AC isolation rating) separates primary power side from relay logic circuits, suppress surge voltage, ground‑loop interference and industrial electromagnetic noise, protect internal relay hardware from field‑side electrical damage.
Multi‑layer protective mechanism: Integrate over‑voltage, over‑current, short‑circuit and over‑temperature protection; automatically shut down at 105 °C over‑temperature condition to avoid module burnout.
Hot‑swap plug‑and‑play: Chassis‑plug‑in modular structure; allow module replacement without powering down the whole UR‑rack under permitted operating conditions, shorten equipment maintenance downtime.
Hardware status indication & self‑diagnosis: Front‑panel LED indicators display power‑on status and fault alarms. Continuous self‑monitoring for input power abnormality, output overload and internal hardware failure. Fault events can be uploaded to EnerVista UR configuration software for system event logging and troubleshooting.
Harsh‑environment adaptability: Conformal coating on printed circuit board, anti‑moisture, anti‑dust and anti‑chemical contamination; withstand vibration and shock for substation and heavy‑industrial cabinet installation.plcva.com
High‑efficiency power conversion: Optimized circuit design with 28 % efficiency improvement versus older generations, reduce heat generation and extend service life of the whole relay system.
