The Sixteen 0-10V Outputs 8-Layer Stackable HAT is the ideal board for controlling a large number of 0-10V dimmers in Building Automation, or any actuator used in Industrial Automation. Expandable to 8 layers, the HAT can provide up to 256 0-10V outputs in a very compact form factor.

DESCRIPTION

24V POWER SUPPLY: Use standard industrial 24V power supply to power the board, or any DC power supply from 10V to 30V. Power requirement is 1A at 24V (24W). The Sixteen 0-10V Outputs 8-Layer Stackable HAT provides 5V and up to 3A to Raspberry Pi and any other HATs you might install on the same stack.

0-10V ANALOG OUTPUTS: Sixteen 0-10V Analog Outputs are available. The outputs are generated using 16 bit PWM timers. Discrete components limit the factory to 1% accuracy, but precision up to 0.1% can be obtained through calibration. Command line functions are provided for analog field calibration.

RS485 COM PORT: The RS485 port can be accessed either from the local processor or from the Raspberry Pi. If the port is controlled by the local processor, the lines to Raspberry Pi are disconnected with jumpers, releasing the pins for other functions. The RS485 is using pins 8 and 10 of the GPIO connector.

STAND-ALONE OPERATION: If the RS485 is used with the local processor, the Sixteen 0-10V Outputs 8-Layer Stackable HAT card can be used stand-alone (no Raspberry Pi needed) and all I/O's can be accessed using standard MODBUS commands.

STATUS LEDs: A power LED is flashing indicating the local processor is active. Sixteen more LEDs can be configured in software to turn on when an output exceeds a predetermined value

HARDWARE WATCHDOG: If the hardware watchdog is activated, the Raspberry Pi has to access the processor at a preset interval to ensure it is still operational. If the Pi fails due to software lockup, the local processor performs a hardware reset by cycling the power.

PUSH BUTTON: The push button can be used to add manual input to any system. The button can also be used by Node-RED or other Raspberry Pi programming in an arbitrary manner.

PLUGGABLE CONNECTORS: Pluggable connectors ease connecting the card to external devices. All the connector plugs are included with the card. To maximize the perimeter space, two level connectors are used for the RTD ports and the serial communication ports.

EXPANDABILITY: The Sixteen 0-10V Outputs 8-Layer Stackable HAT can be used with any Raspberry Pi or in stand-alone mode, connected through MODBUS to any standard PLC. Up to eight Sixteen 0-10V Outputs 8-Layer Stackable HATs can be plugged on top of each Raspberry Pi.

RASPBERRY PI GPIO CONNECTOR: The Raspberry Pi IO Multi-IO HAT uses only the I2C ports to communicate with the Raspberry Pi, leaving all the other GPIO pins available for the user.

SOFTWARE

SOFTWARE INTERFACES

You can write your own application using the Command Line or Python Library provided. No programming is required if you use the Node-Red nodes we supply. You can drag-and-drop the functional blocks to design your application.

Node-RED PROGRAMMING

Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to design flows using nodes from a large library covering a wide range of automation tasks. Native Node-RED nodes are provided to access all the Sixteen 0-10V Analog Outputs HAT functions.
