SM-THERM

SMART-Module with 4 Optoisolated Thermocouple Inputs

 

SM-THERM supports up to four groups of R, S, B, J,T, E or K thermoelement sensors together with a cold-junction for extremely accurate temperature

measurements.

Designed around a fast 16-bit delta-sigma A/D converter, the SM-THERM  ensures an absolute measurement accuracy of 0.2ºC over the complete

operating temperature range of -210ºC to +1820ºC.

 

►      4 thermocouple input groups

►      One, 2-wire PT100 input for cold-junction

►      Open sensor detection

►      Self calibration (on-board EEPROM)

►      Overvoltage protection

►      2 user configurable LEDs
