Acromag software-configured isolated signal splitters

March 1, 2018
The four loop-powered splitter/duplicator models from the SP230 series are Windows or Android-programmable by USB to control two proportional 4-20mA outputs from a single current, voltage, or temperature input signal.

Acromag’s SP230 series of isolated signal splitters/duplicators are designed for easier installation and setup. Four models, covering a broad range of sensor signals, provide dual 4-20mA outputs proportional to a single current, voltage or temperature input. A USB connection to a Windows PC or Android device enables configuration of I/O ranges and a variety of operational settings with free software. The two-wire instruments include plug-in terminal blocks and can acquire power from either output loop. Sink or source output wiring connections are supported. The design operates from -40 to 80°C with high immunity to electrical noise and surge protection. UL/cUL Class 1 Division 2, ATEX Zone 2 and IECex hazardous location approvals are pending.

Each model accommodates a variety of signal types. The current units are adjustable to support ±20mA or 0-20mA DC inputs and 0-20A AC signals with a toroid sensor. Voltage models convert unipolar or bipolar signals from ±1V to ±150V DC with multiple selectable ranges. Thermocouple units accept eight different sensor types (J, K, T, R, S, E, B, N), as well as ±100mV inputs.

The splitters' 1500V AC isolation separates the input from each output circuit and provides continuous 250V AC (354V DC) protection.

SP230 splitters can withstand 25g shock and 4g vibration. The removable screw terminal blocks maintain secure wiring connections. And, spring-loaded DIN rail clips provide mounting.
