Programmable signal splitters are modular

Acromag’s software-programmable microBlox signal conditioning modules can now be used to split or duplicate RTD, thermocouple, two-wire transmitter, and other input signals into multiple process control outputs.

The uBSP signal splitter/duplicator acts as a carrier for the microBlox line of plug-in signal conditioning modules to drive two scalable 4 to 20mA or 0 to 10V control outputs and an auxiliary 5.0V third output from a single input. Users can select from more than 10 miniature signal conditioning modules to process inputs from RTDs, thermocouples, two-wire transmitters as well as a variety of current, mV, or voltage sources. The interchangeable input modules snap into the uBSP carrier which provides input and output terminal blocks as well as a USB port for easy software configuration from a Windows PC or Android mobile device.

The uBSP 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 expensive proprietary cables or adapters to connect with your PC, smartphone, or tablet.

Users can change the input type quickly and inexpensively as requirements change, confirms Acromag. 1500V 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 two, three, or four-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 immune to electrical noise and operate from ‑40 to +75 degree C. Power sources from 6.0 to 32V DC are supported to simplify battery and solar-powered applications. Units mount securely on a DIN rails 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.
