uB30 / uB40
uB30/40: milliVolt Field Input Module
• Field Input: ±10mV to ±100mV ranges
• Host Output: 0-5V or ±5V ranges
The uB30 and uB40 models condition and convert a low-level DC voltage field input signal to a scaled 0-5V or ±5V output. The uB30 has more filtering for low-band applications, while the uB40 relaxes filtering for higher speed applications. uB30 modules are recommended for noisier environments where conversion speed is less of a concern. uB40 modules drive a faster response, but with less filtering for noise.more >
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 uBTA carriers are used with Acromag’s microBlox® signal conditioning modules to create powerful alarms that also provide a voltage/current transmitter output. The plug-in modules offer the convenience of wireless field programming on a smartphone or tablet.
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 sharable 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.
Agility™ Config Tool is available for free.
