Product Description

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.

Frequently Asked Questions about D2-03B-1

How is the D2-03B-1 unit mounted?

As a base unit, the D2-03B-1 model is mounted by securing it to the equipment panel using screws to secure it through the corner/mounting tabs. The D2-03B-1 unit can also be mounted with mounting rails. The rails that are used will conform to DIN EN standard 50 022. The rails required for mounting the base unit to the cabinet are 35 mm high and have a depth of 7.5 mm. Make sure that when the D2-03B-1 model is mounted using rails, you should consider potentially using end brackets on each end of the rail to secure the base, which will help ensure the base does not slide horizontally on the rail. 

What are the power supplies available on the D2-03B-1 model?

There are two power supplies used with the D2-03B-1 model. One is 5 volts or milliamperes, and the other is a twenty-four-volt auxiliary. The power supply for the 5 V device is 2600 mA. The power supply for the twenty-four-volt auxiliary device is 300 V.

Reviews For D2-03B-1

Internal Review

One of the features of the D2-03B-1 model is that due to its expansion suffix of -1, it can be replaced by an existing base without a suffix within the DL205 series. The model can also be used as a local expansion, local base, and I/O configuration. Extra information on the base model can be found in the D2-USER-M Instruction Manual. - AX Control Tech
