uB34, uB35: Platinum RTD Field Input Module
Product short description:
- Bluetooth® wireless configuration option
- Platinum RTD (2,3, or 4-wire) field input
- Voltage host output
The uB34 and uB35 models condition and convert a Platinum RTD sensor or resistance signal to a scaled 0-5V or ±5V output. Both models provide sensor excitation, linearization, lead-wire compensation, lead-break or sensor burnout protection, and input isolation.

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 uB34 and uB35 models condition and convert a Platinum RTD sensor or resistance signal to a scaled 0-5V or ±5V output. For two and three-wire RTDs, use the uB34. Four-wire RTDs use the uB35. Both models provide sensor excitation, linearization, lead-wire compensation, lead-break or sensor burnout protection, and input isolation.
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.

How to Monitor Gensets in Standby Mode to Ensure Reliable Backup Power Application NoteDefining the Problem: Gensets typically include control systems that monitor and control the engine functions. Primary functions are start/stop control, engine speed, operating parameters, and protection/shutdown. As back-up systems, gensets may operate less than 100 hours per year. While in the standby mode, it is critical to monitor and maintain the genset system to prevent...How to Use Signal Conditioners with Built-in Data Logging Application NoteDefining the Problem: A manufacturer of sensors and electrical controls does burn-in testing for troubleshooting purposes. A test system that can operate with either an Android® or iOS® mobile device is preferred. System Requirements: The application requires a product that can monitor a variety of signals, provide analog or limit alarm outputs and have data...How to Measure Voltage of Multiple Cascaded Cells Application NoteDefining the Problem: A proper method is needed to measure each cell voltage within a series of cells and withstand high nominal or open circuit voltages. The maximum series voltage is greater than the common-mode range of the connected instruments. This requires isolated floating inputs to measure each cell voltage. Channel-to-channel isolation will extend the...How to Reduce PLC Costs with Signal Conditioners Application NoteDefining the Problem: A small scale bottling operation will be controlled by PLCs. Multiple sensors including conveyor speed (frequency), bearings temperature (RTD), liquid level (4–20mA) and tank pressure (4–20mA) will connect to the PLCs. An affordable solution to convert these various signals to one common signal type will allow procurement of one type of PLC...Temperature Measurement Select the Best Temperature Sensor for Process Control Applications White Paper (Log in to view the file)How to Select the Best Temperature Sensor for Process Control Applications White Paper Thermocouples versus Resistance Temperature Detectors Many users simply look to fill the basic needs of their application and do not worry much about their choice of temperature sensing technology.
