Core Features & Operating Capabilities
- High-Density Channel Scanning: Supports programmatic selection of active scanning channels (1, 8, 16, 32, 48, or 64 channels), continuously digitizing input signals and automatically updating results in internal memory.
- Independent Channel Gain Control: Allows unique gain configurations per channel via an onboard gain buffer, maximizing dynamic range across diverse analog sensors (such as pressure, temperature, and flow transmitters).
