Abaco Systems / SBS / Greenspring IP-Thermistor 16 Channel Thermistor Temperature Reading IndustryPack

The Abaco Systems IP-Thermistor is an IndustryPack module designed for precise temperature monitoring across 16 independent thermistor channels. This module integrates essential components for accurate thermistor-based temperature readings, including a stable current source, multiplexers, amplifiers, and a 12-bit analog-to-digital converter (ADC). It is engineered for industrial applications where reliable and precise temperature data is critical. The IP-Thermistor utilizes a switched 1 mA current source, minimizing self-heating of the thermistors by sequentially applying the current to each sensor. The conversion cycle for each channel completes within 17 microseconds, allowing for high scan rates up to 58.8 ksamples/sec. The module offers programmable interrupt capabilities or a status bit for host polling upon conversion completion. The 12-bit digitized data is sign-extended to a 16-bit word for accessibility.
