Sixteen 0-10V Analog Outputs 8-Layer Stackable HAT for Raspberry Pi
24V POWER SUPPLY: Use a standard 24VAC transformer to power the board, or any DC power supply from 10V to 24V. 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 from the local processor or the Raspberry Pi. If the local processor controls the port, the lines to the Raspberry Pi are disconnected with jumpers, releasing the pins for other functions. The RS485 uses 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 flashes, indicating that 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:Â 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.
Stacking Multiple Cards: Your Raspberry Pi can support up to sixteen 0-10V Analog Outputs cards. The configuration DIP Switch, with three positions labeled ID0, ID1, and ID2, selects the stack level. Cards can be stacked in any order.
RESET PUSH BUTTON: The push button can add manual input to any system. It can also be used arbitrarily by Node-RED or other Raspberry Pi programming.
PLUGGABLE CONNECTORS: Pluggable connectors make connecting the card to external devices easy. All the connector plugs are included with the card. To maximize the perimeter space, two-level connectors are used for the RTD and serial communication ports.
EXPANDABILITY: The Sixteen 16 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 16 0-10V Outputs, 8-layer Stackable HATs can be plugged into each Raspberry Pi.
RASPBERRY PI GPIO CONNECTOR: The Raspberry Pi IO Multi-IO HAT communicates with the Raspberry Pi using only the I2C ports, leaving all the other GPIO pins available for the user.

SOFTWARE INTERFACES
You can write your application using the Command Line or the Python Library provided. No programming is required if you use the Node-Red nodes we supply. You can design your application by dragging and dropping the functional blocks.
Node-RED PROGRAMMING
Node-RED is a programming tool for wiring 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 an extensive library covering a wide range of automation tasks. Native Node-RED nodes are provided to access all sixteen 0-10V Analog Outputs HAT functions.
