The P900 Remote Oil Temperature Indicator is a microcontroller-based device for transformers, displaying oil temperature (0-150°C std.) on a 3-digit LED, accepting resistance inputs (0-2800Ω), offering adjustable settings (e.g., -50°C to 300°C), providing outputs like 4-20mA for SCADA, and featuring a test key for internal checks, crucial for monitoring transformer health from a distance.
