uBTA-P-1 Series: microBlox® Transmitter and Alarm Carrier

Models

uBTA-P-1MR: Single channel transmitter/alarm, mechanical relays
uBTA-P-1SR: Single channel transmitter/alarm, solid-state relays

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.

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 (either mechanical or solid-state).

Bluetooth® wireless technology enables configuration using an Android™ or iOS® mobile device. Acromag’s Agility™ app helps you quickly set input/output ranges and 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.

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.
