The GSAO-1 Analog Output Module allows H2scan’s modern GRIDSCAN 5000 transformer monitors to be used with established infrastructure that only supports analog inputs.
System engineers can adjust the 4-20mA signal to represent various full-scale values (100 ppm to 5000 ppm), providing enhanced resolution for precise monitoring of transformer health across different age profiles and operating conditions.
The GSAO-1’s IP68-rated construction ensures reliable operation in challenging outdoor environments. Its compact form factor and magnetic mounting capability support straightforward installation on transformer surfaces or within control cabinets. The module includes LED indicators for power and service status, clearly confirming proper operation.
The GSAO-1 is particularly valuable for facilities maintaining mixed-generation infrastructure, where modern communications protocols like Modbus and DNP3 coexist with legacy analog systems. Its modular design approach eliminates unnecessary complexity, reducing installation time and maintenance requirements while enabling facilities to maintain cost-effective hydrogen monitoring capabilities.
