uB49: DC Voltage Field Output Module

Field Output: ±5V, ±10V, 0-5V, 0-10V
Host Input: ±5V, ±10V, 0-5V, 0-10V or programmable ±10V

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 back panels 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 uB49 model conditions a DC voltage signal received from the host system to drive a scaled process voltage field output signal. It functions as an isolated, voltage-controlled voltage source to drive field instruments.

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.
