SP337: Four-wire Process Voltage Input Signal Splitter Description

The SP337 is a high-performance signal splitter that converts one process-level DC voltage input into two isolated proportional control signals. A variety of current and voltage output ranges are supported.

Power connects on a terminal block, a rail bus, or both for redundancy.

High-voltage isolation separates the input from power and 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.

IMPORTANT: To prevent ground loop error between a grounded PC and a grounded input signal, Acromag strongly recommends use of a USB isolator like Acromag’s USB-Isolator when configuring a SP330 Series transmitter.

How to Use Process Transmitters to Provide a High Voltage Output Up to ±20V DC - 8400973
Defining the Problem: We are developing a 12V DC battery simulator that reaches 14.4V when charging. Our controller output cards are limited to 10V and we need a device that can step up the output to 15V. Typical process signal conditioners have standard ranges of 10V maximum. We require a device with a higher output...
