HYDROS 4 Outlet WiFi AC Power Strip

The Starter Pack includes a HYDROS Power 4 WiFi Power Strip. This is a smart power bar designed to work with the HYDROS platform. The Power 4 has four 120V AC outlets and four USB ports that are WiFi controllable using the HYDROS app for Android and iOS/Apple mobile devices.

The Power 4 has a signal range of 98’, so you can place power strips around your home without any difficulty connecting to your modem or router.

Each of the four outlets can be controlled individually while the four USB ports are controlled as one. The outlets have individual LED indicators and the USB ports have a single LED indicator. The status LEDs to indicate whether an outlet is on or off.


Sense Port

The Sense Port is a new concept in aquarium parameter measurement. The HYDROS Control 4 includes four Sense Ports for expanded capabilities. A Sense Port is a generic input port that can accept data from a variety of different types of sensors.


Supported Sensors

  • Temperature probes
  • Optical level sensors (single and dual)
  • Capacitive non-contact liquid level sensors
  • Rope leak detectors
  • Point leak detectors
  • Flow rate sensors
  • Magnetic switches
  • Push-button switches


Drive Port

The four Drive Ports onboard the Control 4 provide switched 12V DC power for running small lights, motors, pumps, fans, and other accessories. The exact current being supplied by each port is continuously monitored by the Control unit, so if a motor or pump quits drawing current or draws too much, you will be immediately notified.


Available Drive Port Accessories

  • Auto Top-Off (ATO) pumps
  • Cooling fans
  • Cabinet LED lights
  • Solenoids to control reverse osmosis systems


Probe Port

One of the most remarkable ports on the HYDROS Control 4 is the Probe Port. The Control 4 includes two Probe ports which can be connected to an ORP or pH probe, but these are no ordinary probe inputs! The circuitry is based on an ultra-high-quality input chip specifically designed for these types of probes. Each pH input provides digital galvanic isolation from the rest of the system which prevents interference with other accessories connected to the system like motors and pumps. Digital Galvanic isolation maintains the accuracy of the measurement by converting the signal to a digital domain before transmitting the information.


0-10V Port

The HYDROS Control 4 has two 0-10V I/O (input and output) ports that allow it to control and receive commands from other HYDROS devices as well as accessories from other brands. A legacy automation system can provide input via the 0-10V Ports. They can control variable speed pumps and can also be used to monitor simple switches, like push buttons or float switches.


Command Bus

The HYDROS Control 4 includes two Command Bus ports which are used to power the Control unit as well as communicate with other HYDROS devices for the ultimate failsafe.
