Product short description:
  • DC current and low voltage input
  • 0-20mA, ±10V outputs
  • 6-32V DC external power

The SP336 is a high-performance signal splitter that converts one DC current or millivolt 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.

SP336: Four-Wire Current / mV Signal Splitter Description

The SP336 is a high-performance signal splitter that converts one DC current or millivolt 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 Display Flow Rate From a DP Transmitter - DP Flow via Square Root Extraction
Acromag Solutions Application Note 8401035 Defining the Problem: A water treatment facility has differential pressure transmitters that output a 4 to 20mA signal to their SCADA system. They also want to be able to display the flow rate to the operators working nearby but the signal from the differential pressure transmitter is nonlinear. System Requirements:...

How to Re-transmit and Isolate 4-20mA Signals from Remotely-Mounted 3-Wire Gas Detection Sensors - 8400957
Defining the Problem: Signals from 3-wire remote sensors that monitor combustible and toxic gases are typically transmitted directly to the remote gas monitor or controller. However, in some cases, it’s desirable to send the signal to more than one destination. This can either be accomplished by re-transmitting the existing signal to additional locations; or by...
