The D2-03B-1 module is considered a base unit in the DirectLogic 205 series produced by Automation Direct. This model is a 3-Base AC slot module. When the model is being stored, the temperature range that is vital to keeping the model from malfunctioning after installation is -20 to 70 degrees Celsius. When the D2-03B-1 unit is being operated, the device must stay at an ambient operating range of 0 and 55 degrees Celsius. One of the three slots of the base is a CPU slot. This base is compatible with H2-DM1 and H2-DM1E Do-More CPUs. The dimensions of the model are 6.77 x 3.54 x 2.95, and the weight is 350 grams. The base has noise resistance thanks to the built-in NEMA casing. To warn the user of potential problems within the system, the base and the compatible modules come with indicator lights. The device is also mountable and is free to be placed anywhere.
The D2-03B-1 is made to run on an AC power supply. The input power type of the device is 110 - 220 VAC. The base's input voltage range volleys between 85 and 132 VAC. There is an 80 VA maximum on the electric power consumption that the device can manage. The inrush current should not exceed 30 amps at any given time. The D2-03B-1 module also has an auxiliary 24 VDC output that adds more power options for the system.
The D2-03B-1 module is used as the base model for units in the DirectLogic 205 (DL205) series; due to the -1 suffix, this model has an additional connector that can be used for local expansion. More information on the base units within the DL205 family can be found in the DL205 PLC D2-USER-M Manual.
