Field Input: 0-20mA or 4-20mA DC
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 uB32 model conditions and converts a DC process current field input signal to a scaled 0-5V or ±5V output. To convert AC current signals, Acromag offers the model 5020-350 toroid sensor which provides a 0 to 11.17mA output. For interfacing two-wire transmitters, please refer to the uB42 which is similar to the uB32 but provides field excitation for the loop-powered transmitter.

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.

For cost-sensitive projects, a commercial-grade version is available (-CG models). These units offer similar performance, but over a limited temperature range and lack hazloc approvals.

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.
