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 uB34 and uB35 models condition and convert a Platinum RTD sensor or resistance signal to a scaled 0-5V or ±5V output. For two and three-wire RTDs, use the uB34. Four-wire RTDs use the uB35. Both models provide sensor excitation, linearization, lead-wire compensation, lead-break or sensor burnout protection, and input isolation.
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 set-point limit and dead band. Other app functions include polling inputs, trending values in a shareable chart, updating calibration, and diagnostic troubleshooting.
Back panels 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.

Channel-to-channel isolation provides optimal noise and surge protection from ground loops, spikes, and high common mode voltages.
The uBDC1 power module allows a backpanel populated with I/O modules to operate off DC power voltage levels other than 5V. This optional module plugs into a special socket on the backpanel to convert a power supply voltage from 10-32V DC to 5V/1A which will drive up to 16 I/O modules. uBDC1 modules include over-voltage, reverse-voltage and short-circuit protection (current limiting).
With the uBDC1 power module, users can also implement redundant power methods for the backpanel. In redundant applications, the uBDC1 becomes the primary power source.
