2 Wire Process/Voltage Input Signal Splitter SP237

The SP237 is a signal splitter that converts one process level DC voltage input into two proportional isolated 4-20mA control signals. Power is received from one or both output loop currents.

The Acromag SP237 is a 2 Wire Process/Voltage input signal splitter.

Firstly, the setup is simple with a USB connection to your PC and Windows Software. Agility is Acromag’s mobile app which allows configuration of the splitter on an Android smart phone or tablet. Software simplifies I/O range scaling, calibration and advanced signal processing capabilities.

Secondly, the high voltage isolation separates the input and between the output circuits. Isolation protects from surges, noise and eliminates ground loop errors. These units are designed to operate reliably in harsh industrial conditions in a wide temperature range.

Finally, to prevent ground loop error between a grounded PC and grounded input signal, Acromag recommend using a USB Isolator.
