uBSP-P-1: microBlox® Signal Splitter Carrier

The uBSP carrier is used with plug-in Acromag microBlox (uB) input modules to build a flexible signal splitter/duplicator. Select from a variety of uB modules to match your input signal type for conversion to two proportional process current or voltage outputs. A third auxiliary voltage output is driven directly by the uB module.

High-voltage isolation separates the input from each output circuit. The isolation protects from surges, reduces noise, and eliminates ground loop errors.

Setup is fast and easy with a USB connection to your PC and our Windows software. Acromag’s Agility™ mobile app enables configuration on an Android smart phone or tablet. Software simplifies I/O range scaling, calibration, and advanced signal processing capabilities.

These rugged instruments withstand harsh industrial environments to operate reliably across a wide temperature range with very low drift. They feature high immunity to RFI, EMI, ESD, and EFT, plus low radiated emissions.

AUX Voltage Ouput

The local AUX voltage output is equivalent to that produced by the microBlox® module itself when plugged into this carrier. Its signal return COM is common to the USB signal ground, which may be common to earth ground of the host PC if not using a USB isolator.
Voltage Range (AUX): 0-5V, ±5V, or 1-5V, equivalent to the microBlox module voltage output. Refer to module specifications.
Accuracy (AUX): ±0.05% of span typical (from module). Refer to your module specifications for details.
