Additional Information

Schneider Electric 140DDI35300 Overview

The Modicon 140DDI35300 is part of the Modicon Quantum automation platform. It is a low voltage DC discrete Input Module with 32 inputs. It has 4 groups of channels with 8 inputs each and a positive logic input. The module requires a Bus current of 330 mA and has an addressing requirement of 2 input words. It accepts 24 Volt DC inputs and should be used with a shared input common wired to a positive potential and is for use with source output devices. It has no internal fuses, but external fuses can be used at the user’s discretion.


The number of channels on the Modicon 140DDI35300 is 32 sigh 4 groups of 8 channels per common. This module is isolated by group, it uses a sink logic circuit. The 140DDI35300 has two I/O words and is resistor limited. The require bus current is 330 mA and the power dispensation is 1.7 + (0.36 x no. of channels at state 1) in W. This module is configured online and can be modified online. It carries the approvals of UL 508, CSA 22.2-142, e, FM Class 1 Div. 2, and ATEX Zone 2/22. The Modicon 140DDI35300 discrete input module is a non-interfering module that is completely suitable to work in tandem with a Quantum safety configuration.

The input for the Modicon 140DDI35300 is 24 V c.


The CCOTF function, or the change configuration on the fly function, is permitted by the discrete I/O m module 140DDI35300. Which CPU’s support the CCOTF function? The CCOTF function is only supported by Standalone CPU modules from version 5 or later of Unity Pro. CCOTF is also supported by Hot Standby CPUs from version 4.1 or later of Unity Pro. Why is the CCOTF function beneficial? The CCOTF function is beneficial as it avoids the interruption of processes. How does this help? This is useful as it helps reduce production costs.

How to use a 140DDI35300

The 140-DDI-353-00 Module, when in “ON” mode, should be kept at a voltage of 5 to 30 Vdc, and a minimum current of 2.0 mA. When Off, the voltage should read between -3 to 5 Vdc and keep at a max current of 0.5 mA. Its response time between the On and Off functions is 1 ms. The 140DDI35300 has no-fault detection. Its power dissipation is 1.7 Watts plus an additional 0.36 Watts for every input that is in use. The absolute maximum continuous input should be kept under 30 Volts DC. Its maximum input at 1.3 ms should be a 56 Volt DC decaying pulse. 140DDI35300 uses a resistor limited input protection, and it has an internal resistance of 2.5k. External power is not necessary for this module. On its front panel, it has a total of 32 green LEDs that indicate the status for each point. This module is of standard size and can fit into any Modicon Quantum backplane easily.

The Modicon 140DDI35300 discrete I/O Module by Schneider Electric comes with a two-year warranty.
