Schneider Electric 140DAI55300C Overview

The Modicon 140DAI55300C is a discrete input module working with a voltage of 115 V ˞ with 32 inputs. It does this with 4 groups of 8 inputs. It weighs 0.728 lbs.

The ability to add and or remove discrete as well as analog I/O modules has never been easier with the Modicon 140DAI55300C module. This module is compatible with the Quantum CPU, or central processing unit, is a product of Schneider Electric. Schneider Electric is one of the most trusted names in automation and you can be sure the unit 140DAI55300C is on par with all units in this automation line where quality is concerned.

Useful online function modification configuration, also called CCOTF, can be used.  This is changing the configuration on the fly is useful to add or remove discrete or analog I/O modules with the Quantum PCU configuration while it is in RUN mode. Another thing it does is enable Ethernet RIO drops that are supposed to be added in the RUN mode which is going to requires Unity Pro on some CPU modules. You can configure parameters of new I/O modules that already exist right online. This eases interruptions that con be disruptive to your system. 

Supporting the CCOTF function are some (version 5 or later of Unity Pro) standalone CPU’s and also (version 4.1 or later Unity Pro) Hot Standby CPU’s.

Which *standalone CPUs and which **Hot standby CPUs support this discrete I/O module? The following are considered compatible with the 140DAI55300C:

The product is considered a VAC discrete input module and works communicating input to the CPU, the brains of your system. It utilizes the 4 channel groups to address the 2 input words using 115 V AC. Response time can be critical. Knowing how quickly your input brings this information is important. So, what exactly is the response time with this Modicon input unit? The response time is 4.9…0.75 ms x line cycle Off-On and 7.3…12.3 ms On-Off. 

The local signaling indicators on this unit uses LED to signal. It offers the following: 1 LED (green) bus communication is present and will indicate (Active), 1 LED (red) external when a fault is detected, and will indicate (F), and finally there are 32 LEDs (green) which are there for input status.

Everyone incurs varied monitoring of program disparity, and we understand that you may have a redundant PLC application that requires you to utilize identical application programs on more than one CPU. What happens then? A comparison is then required for both PLC’s and it will occur at once when the system is powered up. It will keep repeating when the standby system is still active. When a difference in the program is detected, by default, the PLC that is in standby will disconnect from the system. Applications for this unit are as varied as automation needs. 

Schneider Electric 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.
