Product Description

The X20ATC402 module is a highly versatile thermocouple input module that offers effective data conversion and monitoring ideal for industrial temperature measurement applications. It has a broad range of compatibility with different thermocouples such as J, K, N, S, B, R, E, C, and T which makes it very suited for many temperature surroundings.

The monitoring features of the module are quite broad and include a range of undershoot and overshoot detection (0x8001 for undershoots and 0x7FFF for overshoots), open circuit detection, and general errors (0x8000). It uses the sigma-delta conversion technique which is known for its high resolution and accuracy together with internal linearization for enhanced measurement. The primary accuracy of the system is quite high with an error of ~0. 06%, with exceptional common-mode rejection rates-greater than 100 dB for DC, 50 Hz, and 60 Hz-demonstrating its effectiveness in cancelling out unwanted noise and interference. The input handling is also quite good with a permissible signal range of ~15V and a common-mode range of ~14V. The inputs are first-order low-pass filtered with a cut-off frequency of 500Hz to ensure a clean and accurate signal. Schemes for terminal temperature compensation are incorporated with PT1000 temperature sensors for improved measurement precision.

The module's isolation voltage is 500 V between channels and the bus, to protect against interference and maintain signal quality at the inputs. It can be wall mounted either horizontally or vertically and the working temperatures for the unit are from -25 to 60 degrees C for the horizontal mode and from -25 to 50 degrees C for the vertical mode. Storage conditions are also quite liberal, ranging from -40 degrees C to 85 degrees C, making it easy to transport and use the device. The product is available at Wake Industrial with a one-year warranty period.
