uB37, uB47: Thermocouple Field Input Module Description

Field Input: T/C type J, K, T, R, E, S
Host Output: 0-5V or ±5V ranges

Acromag’s microBlox® uB Series I/O modules offer a compact, high-performance solution for interfacing sensors and field devices with data acquisition systems. uB signal conditioning modules are ideal to isolate, filter, convert and amplify a wide variety of signal types for test, measurement and control systems. Just plug uB modules into 4, 8, or 16-channel backpanels in any mix for a high-density analog I/O interface. Channel-to-channel isolation provides optimal noise and surge protection from ground loops, spikes, and high common mode voltages.

The uB37 and uB47 models condition and convert low-level input voltages from field thermocouple sensors to a scaled 0-5V or ±5V output. On uB37 models, output is linear with thermocouple voltage, while uB47 output is linear with thermocouple temperature. Both models have up/downscale sensor-break detection. Cold junction compensation is performed on the backpanel.

Bluetooth® wireless technology versions enable configuration using a smart phone or tablet. Acromag’s Agility™ app, available for Android™ and iOS® mobile devices, helps you vary input/output ranges and scaling to your specific application. The Agility app can also set an alarm output function with a setpoint limit and deadband. Other app functions include polling inputs, trending values in a shareable chart, updating calibration, and diagnostic troubleshooting.

Backpanels provide power, I/O wiring terminals, and host access to an industry-standard analog signal bus. Modules are hot-swappable without screws. Data acquisition boards can access all host I/O signals on the DB25 bus connector.
