Technical Data ATSAMD21G18 Microcontroller 128x64 px LCD Screen with Backlight Membrane 3 Button Panel Ethernet Module (mandatory) M2M 3G/LTE Router optionally available Standard Input Voltage: 12V / 24V DC permissible range: 8–28V DC 12V, 24V PSU optionally available DIN-Rail mountable 4 Analog Input Channels 2 Analog Output Channels Levels: 4–20mA / 0–10V Fully isolated from MCU and Digital Side (1kV isolation) 8 Digital I/O Channels Digital Input Voltage Range: 0–28V input channels internally driven LOW Digital Output Vortage Range: 8–28V (tied to VIN) Digital I/O Levels: LOW ≤ 3V, HIGH ≥ 11V I/O Logic is active high Max. Output Current per Pin: 2.6A (short circuit, over-current, over-temp. protected) Max. Total Output Current: 6.5A (omni block fused) Fully isolated from MCU and Analog Side (1kV isolation) Isolated Half Duplex RS-485 Transceiver Important Notes To properly operate the Raindancer Beacon, it has to be connected to an adequate power supply via the POWER-IN field (12/24V DC is recommended). The USB port on the front casing is not suitable. When a single power supply is used to power both, Raindancer Beacon and peripherals, the GND lines should be tied together. Power down all systems (Raindancer Beacon, sensors/actuators) before connecting to the Raindancer Beacon via USB, internal components may irreparably take damage otherwise! Analog Field Section Analog Pins can be individually configured, according to the requirements of the devices to be connected: 0-10V or 4-20mA. By default, all Analog Pins are preconfigured to 4-20mA. An alternate configurations can be set using the web-portal. Pin Assignment and Value Ranges when Used as Pump Control Unit: The value ranges can be individually adjusted using the web-portal. A OUT Assignment Default Range CH 1 Target / Min. Pressure 0 – 16 bar CH 2 Manually Set Pressure 0 – 16 bar A IN Assignment Default Range CH 1 Current Pressure 0 – 16 bar CH 2 Current Power 0 – 100 kW CH 3 Current Flow 0 – 100 m³/h CH 4 Current Speed 0 – 3.600 rpm Digital Field Section Output can be configured as a permanent or pulsed signal (125ms – 256s).  Signal configuration can be adjusted using the web-portal. Pulse counter (using level raise/fall, max. ca. 60Hz), e.g. for water meters on Digital Channel 8. Please note that floating/pulsing input voltages may be transmitted as highly fluctuating input signals, triggering associated actions (e.g. error notification). Default Pin Assignment and Value Ranges When Used as Pump Control Unit: D CH Assignment Signal Interpret. 1 (OUT) Control ON Pulse, 125ms ON 2 (OUT) Control OFF Pulse, 125ms OFF 3 (IN) Confirmation Permanent ON/ OFF 4 (IN) Error Code 1 Permanent ON/ OFF 5 (IN) Error Code 2 Permanent ON/ OFF 6 (IN) Error Code 3 Permanent ON/ OFF 7 (OUT) Reset Error Pulse, 2s 8 (IN) Counter Pulse Error Codes By combining the three main Error Codes using Digital Channels 4 – 6, four additional states, up to a total of 7, can be transmitted. • The textual interpretations of the Error Codes can be customized individually using the web-portal. Default Error Codes Used by Pump Control/Monitoring: Code 1 (CH 4) Code 2 (CH 5) Code 3 (CH 6) Interpretation 0 0 0 no malfunction 1 0 0 Malfunction - Pressure, generic. 0 1 0 Malfunction - Motor Temperature 0 0 1 Malfunction - Frequency Inverter / Pump 1 1 0 Malfunction - Low Pressure 1 0 1 Malfunction - Excess Pressure 0 1 1 Restart after Interruption of Power Supply 1 1 1 Remote Control Disabled
