A902 1/2/3 Adaptor Cable

While a regular Y-cable lets you connect two sensors to one port, these two sensors still need to come with different pin-outs on the connector. You could obviously not connect two analog sensors which both require to be connected to e.g. Pin 2 of the RTU port.

This special 1/2/3 cable let's you do just that. It's internal wiring always directs the sensor to the correct port on the RTU. With this cable you can even connect three identical sensors to the same port!

That means that whichever cabling the sensor uses that you have just connected to connector 1 of this cable - it will always end up using cabling 1 on the RTU. Whichever cabling the sensor uses that you have just connected to connector 2 of this cable - it will always end up using cabling 2 on the RTU, and so on.
