Models

uBTA-P-2MR: Dual transmitter/alarm, mechanical relays
uBTA-P-2SR: Dual transmitter/alarm, solid-state relays

The uBTA carriers are used with Acromag’s microBlox® signal conditioning modules to create powerful alarms that also provide voltage/current transmitter outputs. The plug-in modules offer the convenience of wireless field programming on a smartphone or tablet.

The microBlox uB modules offer a flexible space-saving solution for isolating, monitoring, and converting industrial sensor signals to interface with your data acquisition or control system. By inserting a uB input module into the carrier, you get a device with both alarm and transmitter capabilities. With a broad selection of uB input modules, you can monitor many different signal types by simply interchanging modules on the carrier.

Plug-in modules measure current, voltage, thermocouple, or RTD input. Carriers produce a process current and voltage output signal and trip alarm relays if high or low limits are exceeded.

Each alarm carrier has two independent relay contacts (mechanical or solid-state) per channel.

Bluetooth wireless technology enables configuration using an Android™ or iOS® mobile device. Acromag’s Agility™ app helps you quickly set input/output ranges scaling to your specific requirements. It is also fast and easy to configure your alarm setpoints. You can define two high limits, low limits, or window alarms for each relay of a channel.

These rugged carriers are well-suited for use in harsh industrial environments. Carriers mount on T-type DIN rails for high-density installation. They have high immunity to noise, surges, shock, vibration, and extreme temperatures. Installation in hazardous locations is also supported with compliance to CE, ATEX, and UL regulations.

  • Description

    Field Input: 0-20mA or 4-20mA DC ranges
    Host Output: 0-5V, 1-5V 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 uB42 model conditions and converts a DC process current field input signal from a 2-wire transmitter to a scaled 0-5V or ±5V output. It provides field excitation (12V/22mA) for the transmitter and is useful to isolate non-isolated transmitters. This module can also interface AC current signals with the model 5020-350 toroid sensor producing a 0 to 11.17mA input.

    Bluetooth wireless technology versions enable configuration using a smart phone or tablet. Acromag’s AgilityTM app, available for AndroidTM 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.
