For the Wavelet V2, LoRaWAN V2, and Ex V2. A V2 has 3 physical sensor ports and supports up to 12 sensors using splitters. Unlike the 4R splitters, V2 splitters are signal-specific — match the splitter to the type of sensor you're connecting on that port.

Check your model before ordering. These are not interchangeable with Wavelet 4R splitters. The model is printed on the label inside the enclosure door.

Which splitter do I need?

First identify your sensors' signal type, then the number of sensors on that port:

• 4–20 mA (analog) — for pressure transducers and analog instruments. Available 2-port (WA00158) or 4-port (WA00157).
• RS485 / SDI-12 (serial) — for digital instruments such as Aqua TROLL sondes and Modbus devices. Available 2-port (WA00156) or 4-port (WA00155).
• Pulse, M12 5-pin (WA00146) — 2-port, for dry-contact and pulse devices like tipping-bucket rain gauges and pulse-output flow meters.

Mixing signal types? That's fine — a V2 has three independent ports, so you can run a 4–20 mA splitter on one port and a serial splitter on another. Order one splitter per port you're expanding.

You'll also need one M12 connector per sensor, and typically sensor setup per added sensor.
