Jebao/Jecod Pump to Neptune Systems Apex Controller Linkage Adapter
This new product from Jebao allows for you to control 2 RW, DC or WP series pumps using the 0-10v output from an aquarium controller. The default connector will hook up to an Apex, however any controller with a 0-10v output will work, you simply need an ethernet cable to connect to the adapter.
Each pump can be controlled independently, and you can use the power supply already included with the pump to power the adapter.
Each adapter includes a 6 month US warranty.
