Introduction

Our UMDAS TH and UMDAS TC remote analog input modules are ideal for high-resolution temperature measurements anywhere in your plant. These modules provide 8 differential temperature input channels plus 8 independently programmable digital I/O channels. UMDAS TC accepts thermocouple inputs. UMDAS TH accepts thermocouple, RTD, thermistor, and semiconductor inputs.

Two integrated CJC sensors enhance accuracy, and an open-thermocouple feature automatically spots broken thermocouples. An on-board microprocessor with EEPROM memory automatically linearizes the measurement data. The module is fully software calibrated, and all configurable options are software programmable.
