Please sign in or register to see model options and to add products to your cart.
Product short description:
- Multi-range ±15V, ±75V, or ±150V input
- 4-20mA outputs (sink/source)
- 7-32V DC loop/local power
The SP238 model is a high-performance signal splitter that converts one high-level DC voltage input into two proportional isolated 4-20mA control signals. power is received from one or both output loop currents.

SP238: Two-Wire High Voltage Input Signal Splitter Description
The SP238 model is a high-performance signal splitter that converts one high-level DC voltage input into two proportional isolated 4-20mA control signals.
Power is received from one or both output loop currents.
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.
High-voltage isolation separates the input and between the output circuits. The isolation protects from surges, reduces noise, and eliminates ground loop errors.
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 SP230 Series transmitter.
