Key Features
High-Density Multi-Channel Input: Provides seven independent input channels in a compact VersaMax form factor for comprehensive temperature monitoring .
Versatile Input Compatibility: Supports J, K, T, S, R thermocouple types and a range of millivolt signals, covering diverse industrial temperature measurement needs .
High-Accuracy Conversion: 16-bit resolution with individual A/D converters per channel ensures precise analog-to-digital signal conversion .
Flexible Cold Junction Compensation: Features four CJC modes — local, remote, fixed, or no compensation — for accurate temperature readings .
Automatic Calibration: Performs A/D calibration on startup and repeats it periodically to compensate for ambient temperature drift .
Comprehensive Diagnostics: Detects and reports open thermocouple, over-range, under-range, high/low alarm, and thermistor fault conditions .
Compact Design: Space-saving module that reduces panel footprint and installation costs .

Application Scenarios
