The D0-06DD2-D is a DL06 base unit belonging to the Direct Logic 06 series by Automation Direct. This base unit has a DC power supply with a voltage range from 12-24 Volts DC or 20 Watts. It has 20 sink/source DC input points and 5 isolated commons. The D0-06DD2-D unit can sustain an input voltage range from 12 to 24 Volts DC. Its input impedance rating is either 1.8K at 12 to 24 Volts DC (X0-X3) or 2.8K at 12 to 24 Volts DC (X4-423). The on current is 5mA with a voltage level of 10 Volts DC or higher and the off current is 0.5mA with a voltage level of 2 Volts DC or lower. The typical off to on and on to off response time is 4mS; however, the response time can range from 2 to 8mS.
Automation Directs’ D0-06DD2-D base unit also has 16 sourcing DC output points with 4 isolated commons. The rated output voltage range is from 12 to 24 Volts DC with a peak voltage of 30 Volts DC. The maximum frequency supported by points Y0 and Y1 are 10kHz. The on voltage drop at points Y0 and Y1 is 0.5 Volts DC at 1 ampere and the on voltage drop at points Y2-Y17 is 1.2 Volts DC at 1 ampere. The output points on this unit can support a maximum current of either 0.5A or 1.0A—it is important to double check which output point is being utilized and the output specifications of that point. The maximum leakage current you can expect from this unit is 15 µA at 30 Volts DC. The status indicators for the D0-06DD2-D are located on the logic side of the unit. Please note that this unit does not have fuses and external fuses are recommended to protect the system.
