Humidity: 5% ~ 95% RH (non-condensing)
Power Supply: 24VDC powered via system backplane, maximum power consumption 4.2W
Hardware Features: Hot-swappable, single-channel fault diagnosis, overvoltage and overcurrent protection
Communication: Ovation backplane bus protocol, compatible with HART 7.0 fieldbus protocol
Main Applications
Designed specifically for acquiring weak millivolt-level analog signals from the field, commonly used in:
– Temperature measurement and thermocouple signal acquisition in boilers within thermal power, hydropower, chemical, and metallurgical industries
– Data acquisition from pressure, displacement, and weighing transmitters using millivolt signals
– Centralized monitoring, interlock control, and data uploading to higher-level computers in Ovation systems
Product Features
Industrial-grade wide-temperature design compliant with NERC and IEC 61508 safety standards for the power industry
Electrical isolation per channel effectively prevents signal drift and module damage caused by strong field interference
Supports hot-swap replacement without system shutdown, significantly reducing maintenance downtime
Long-life industrial components with MTBF (Mean Time Between Failures) ≥ 1.5 million hours
