    Battery is automatically charged with no external charger controller required. The maximum current for the charger on the DACC2000 is 4 Amp. This limits the maximum size of the solar panel controlled by the DACC2000 to 70 watts. If a larger solar panel is required, an external battery charging regulator must be used.

Jumpers are provided for each analog channel of the DACC2000, as illustrated in Figure 2.3, to configure shunt resistors for each channel. JP4 through JP7 are used to connect 250 shunt resistors to each channel for using 4 to 20 mA input signals.

    Each channel has an LED to indicate when the channel is energized. 2.2.5 Analog Outputs The two optional Analog outputs of the DACC2000 each generate a 4 to 20 mA DC output (which is normally required for process actuators) or a 1 to 5 volt output. The outputs are normally powered by the DACC2000 but can be powered from an external source.

    Withstand Test. 4.2.1 Analog Inputs The DACC2000 has 4 external analog input channels configurable for a range of 1 to 5 Volts or 4 to 20 mA. The DACC2000 also measures two internal signals. These are battery voltage and charger voltage. All inputs are measured by a successive approximation analog-to-digital converter with 12 bits of resolution.

  • Page 22: Status Inputs

    4.2.2 Status Inputs The DACC2000 has 4 optically isolated digital (status) inputs. Figure 4.2 shows the circuit for one channel of the four. Each input is differentially surge protected with Metal-Oxide-Varistors to IEEE 472-1974. The input pull-up current for dry contacts is supplied from the DACC2000 internal power.

    DACC2000 DIGITAL OUTPUTS SIMPLIFIED SCHEMATIC 4.2.5 Analog Outputs The DACC2000 has 2 analog output channels. Each channel provides a 1 to 5 Volt or 4 to 20 mA output. Output power can be provided by the DACC2000 or Externally. Each Digital-to- Analog converter has a resolution of 12 bits, and the analog output circuit provides an overall accuracy of better than 0.1%.

    OPERATION 4.2.8 Communications The DACC2000 has 4 serial communications ports (Figure 4.8). Three ports provide for RS-232 voltage levels and use standard DB-9 connector pinouts. Pin 4, the DTR pin, has 6.5 volts DC. This pin can be used either as DTR or can provide low current to a device attached to the port.
