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.
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.
