uBTAX-H-1: Transmitter The uBTA carriers are used with Acromag’s microBlox® signal conditioning modules to create powerful transmitters that provide a voltage/current 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 innovative 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, frequency, thermocouple, or RTD input. Carriers produce a process current and voltage output signal. 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. Carriers mount on T-type DIN rails for high-density installation. They can plug together for modular expansion with a shared power connection that is bussed along the DIN rail. Redundant power sources are supported. These rugged carriers are well-suited for use in harsh industrial environments. 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.
