Analog I/O module TBSPT8

8-channelfor temperature sensorsconfigurable

The TBSPT8-DR is a precision 8 – channel PT100/PT1000 interface. Measurement and configuration is controlled via SDI-12 commands. The interface is equipped with 4-wire inputs, matched noise filters, surge- and over voltage protection. To achieve high precision, the TBSPT8-DR is calibrated to an absolute accuracy of ±0.02°C at 0°C, using a ±0.005%, ± 2ppm/°C resistance standard. The device has a resolution of 0,001°C and a temperature drift less than ±0,01°C over the temperature range -40°C to + 80°C. Noise is ±0,0015°C when used with PT1000 sensors and ±0,01°C when used with PT100 sensors. The device can output the measurement results in °Celsius or °Fahrenheit.
