Acromag uBSP signal splitter/duplicator

The uBSP signal splitter/duplicator, from Acromag, acts as a carrier for the microBlox line of plug-in signal conditioning modules to drive two scalable 4–20 mA or 0–10 V control outputs and an auxiliary 5 V third output from a single input.

Users can select from more than 10 miniature signal conditioning modules to process inputs from RTDs, thermocouples and two-wire transmitters as well as a variety of current, millivolt or voltage sources. The interchangeable input modules snap into the uBSP carrier, which provides input and output terminal blocks plus a USB port for easy software configuration from a Windows PC or Android mobile device.

This modular, programmable approach provides a flexible solution to many complex signal-splitting applications. The signal splitter’s USB port allows users to customise the I/O ranges, scaling and other operations driven by the inserted microBlox signal conditioning module. The powerful configuration software is free and a common mini-B USB port eliminates the need for proprietary cables or adapters to connect with the user’s PC, smartphone or tablet.

With the plug-in modules, users can change the input type quickly as requirements change. 1500 V isolation safely separates the input from each output circuit to prevent damage to other instruments from surges. Two-wire transmitter input modules provide field excitation for the transmitter. RTD input modules support 2-, 3- or 4-wire sensors with excitation, linearisation, lead-wire compensation and break detection functions. Thermocouple input modules support types J, K, R, S, T and E with linear or non-linear output.

Units are highly immune to electrical noise and operate from ‑40 to +75°C. Power sources from 6–32 VDC are supported to simplify battery and solar-powered applications. Units mount securely on a DIN rail with 25g shock and 4g vibration resistance. Hazardous location approvals are pending for UL/cUL Class 1 Div 2 and ATEX/IECex Zone 2 standards.
