The OMB-DAQ-TC-RACK and OMB-DAQ-TC-RACK-EXP32 offer exceptional performance and accuracy for thermocouple measurement applications at a low cost per channel. Offering both Ethernet and USB ports, the OMB-DAQ-TC-RACK provides 32 channels of 24-bit resolution for medium channel installations. The OMB-DAQ-TC-RACK-EXP32 adds 32 high-precision channels to support larger installations. Accuracy is designed into the product with sigma-delta 24-bit ADCs, differential inputs, thermocouple-to-host isolation and cold-junction compensation (CJC) for each channel to reduce the effects of thermal gradients. With digital alarming notifications when a temperature exceeds programmed limits, the OMB-DAQ-TC-RACK and OMB-DAQ-TC-RACK-EXP32 offer the perfect solution for temperature monitoring applications including server rooms, refrigerated storage, and long-run test cells.
