4 Wire High Voltage Input Signal Splitter SP338

The SP338 is a signal splitter that converts one high level DC voltage input into two isolated proportional control signals. There are a variety of current and voltage ranges such 0-20mA, 4-20mA, ±5V, ±10V, 0-5V, 0-10V outputs available.

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

The Acromag SP338 is a 4 wire high voltage input signal splitter.

Firstly, high voltage isolation separates the input from power and each output circuit. Isolation protects from surges, reduces noise and eliminates ground loop errors.

Secondly, the set up for this splitter is simple and easy with a USB connection to your PC and Acromag’s Windows Software. Agility is Acromag’s Mobile App which allows configuration of the splitter via Android Mobile or Tablet. Software simplifies I/O range scaling, calibration and signal processing capabilities. These rugged instruments, withstand harsh industrial environments and operate over a wide temperature range.

However, in order to prevent ground loop error between a grounded PC and grounded input signal – it is strongly suggested to use a USB Isolator when configuring a SP330 Series transmitter.
