Electrical Specifications: Powered by 24 VDC and supports redundant power input. It features 4 fully independent MPU input channels. The input accepts AC voltage ranging from 1.5 Vac to 50 Vac with a frequency range of 0.1 Hz to 10 kHz. It provides galvanic isolation of 2500 VAC between channels and between each channel and ground. Power consumption is less than 8 W, and the response time is below 50 microseconds.
Mechanical and Protection Features: IP20 protection rating for cabinet installation. It adopts standard 3U rack mounting structure and fits into industrial control cabinets. The reinforced circuit board assembly can withstand vibration and shock encountered in power generation and turbomachinery sites.
Core Characteristics: Four isolated channels eliminate signal crosstalk between different speed pickup sensors. High voltage isolation protects the main control unit from sensor side surge interference. It provides stable signal conversion for low-speed and high-speed rotating equipment. LED indicators offer channel status and fault diagnosis for convenient on-site troubleshooting. The rugged construction supports continuous long-term operation in turbomachinery control and overspeed protection systems, and is fully compatible with Woodward turbine governor platforms.
