Schneider Electric 140DAO84210 Overview

The Modicon collection of I/O modules is encompassed under the Schneider Electric automation platform, assuring you the quality and durability of the brand you have come to trust with your automation needs.  The Modicon 140DAO84210 module is a discrete output module and part of the Quantum line of components dealing with input and output of power loads. These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry I/O Modules from other manufacturers such as Modicon and ABB.


The 140DAO84210 Modicon module and its components consist of a front panel that displays a model number, a module description, and a color code at the top center.  At the top, underneath the model number, you will find the LED display. On the front of the module, in the center, you will find the fuse cutouts. The fuse cutout area is where the field wiring terminal strip is secured. Please note that the field wiring terminal strip is to be ordered separately.  The terminal strip includes a door and a label.  The door is removable. The label is for identification purposes and must be placed inside the door of the strip.  To do this you must fold the label in half and place it inside the flap of the door. Close the door of the strip securely.

This Modicon component is an AC discrete output module with 16 discrete outputs.  It comes with four groups of four channels which total the 16 output.  The supply frequency is 47…63 Hz with a maximum voltage drop of 1.5 V. The discrete output voltage on this module is 83…253 V AC. It has one output word addressing requirement.  The absolute maximum output on this module is 300 Vrms for 10 s AC and 400 Vrms 1 cycle AC. The response time for this module is <= 0.5 ms at state 0 to state 1 and < 0.5 ms at state 1 to state 0.  You can find an indication of a blown fuse or an indication of a loss of field power by checking the fault indicator.  For protection, it has an internal by RC filter and internal output protection by 5 A fuse.


The automation environment should stay at a relative humidity of 95 % without condensation. It should be operated at an altitude of <= 5000 m. For operation, the ambient air temperature should be between 0…60° C and the ambient air temperature for storage should remain between -40…85° C.  Adherence to these temperature guidelines ensures the best possible outcome with this product.

The Modicon 140DAO84210 carries both the CUL and the FM Class 1 Division 2 certifications.

How to use a 140DAO84210

The bus current requirement for this unit is 350 mA with a standard module format.  You will find a green LED bus indicating the module is active and that means communication is present. If you see a red LED it is an indication that an external fault is detected.

The Schneider Electric brand carries with it the promise of sustainability.It offers Green Premium products driven by proactive compliance. 

This means the EU RoHS Declaration. A mercury-free product, it also carries the China RoHS declaration.
