This is the deluxe controller with pH circuit and includes one 8 outlet AC power bar for Reef-pi fully assembled. Although plug and play you still need to load Reef-pi on your Raspberry Pi and plug it into the controller. The controller board will be mounted in the case, you just need to remove the lid and the Raspberry Pi plugs in. Here's a manual showing how to do that.

Installing Raspberry Pi in Controller

The controller has a fully isolated pH circuit built in, simply plug in any pH probe with a BNC connector and you're ready to accurately monitor your pH.

Available with North American and Australian outlets, both are 240v compatible so adapters for your country can be used.

Package Includes

• Deluxe controller installed in 3D printed case
• Face plate installed on case
• Sensor extension installed in 3D printed case
• 8 Outlet AC power bar installed in case - select type on right side
• 21 2-4 pin pluggable screw terminal connectors
• 3ft USB-A Male to Male cable 

Parts Required

• Raspberry Pi Zero W, Pi 3 or Pi 4 - EXAMPLE
  
• 12v DC power adapter to power up the controller and Raspberry Pi, between 3-10 Amps depending on the DC equipment you connect - EXAMPLE
• Straight Through DB9 9 pin Serial cable to connect power bar to controller - EXAMPLE
• AC Power Cord to power up AC power bar - EXAMPLE
• If you want to monitor pH you need a probe - EXAMPLE

3D Printed Cases and Face Plate

The controller and power bar comes in a 3D printed case, choose your choice of color on the right side and select which Raspberry Pi you'll be using as the case is custom to it. There many be small defects due to 3D printing but any will be minor and only have a visual effect.

8 Outlet AC Power Bar Circuit Board

The AC power bar circuit board can handle 10 Amp at 120v - 240v, The power bar has no wires internally and is protected with a replaceable 10 Amp fuse. 5 of the 8 relays are protected with a heavy duty snubber so they won't be damaged from inductive loads such as motors. 

• 8 switchable outlets
• On board 5x20mm replaceable 10 Amp fuse
• 120v - 240v AC Input / Output
• Each outlet can support up to 10 Amps
• Power Bar can support up to 10 Amps maximum between all 8 outlets
• Heavy duty snubbers protecting 5 relays from inductive loads
• Connects to controller using a straight through DB9 9 pin Serial cable (not included)

Ports, Ports and more Ports

There are a total of 40 ports, as the board comes you can connect any any combination of the following up to a count of 40.

• Up to 24 relays for AC outlets
• Up to 8 DC powered devices (12v default, with external power supply 6v-30v)
• Up to 21 digital sensors
• Up to 8 5v/10 PWM or Analog ports
• DS18B20 temperature sensors (multiple sensors technically share a port and can only use one port)
• Up to 4 pH circuits

This is how I've allocated the ports using specific connectors to make connections easy. The above list reflects what can actually connect to these ports, these are only labels. For example, after 16 relays you would use some 5v PWM ports or use some relay ports for more digital sensors.

• 16 Relays for AC Outlets - two DB9 serial sockets
• 7 Heavy Duty DC Ports - each port has a 2 pin pluggable screw terminal connector
• 1 Auto Feeder Port (standard DC) - uses a 3 pin pluggable screw terminal connector
• 3 Emergency Backup Float Switch Ports - uses a 2 pin pluggable screw terminal connector
• 3 Digital Sensor Ports - each port has a 3 pin pluggable screw terminal connector
• 3 Digital Sensor Ports - uses a USB-A female socket 
• 8 Configurable 5v/10v PWM or Analog Ports - uses two 4 pin pluggable screw terminal connectors
• 3 DS18B20 Temperature Ports - 3 use a 3 pin pluggable screw terminal connector, 4 use header pins
