The Modicon 140DDI35300 is part of the 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 140-DDI-353-00 Module when On 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 kept 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. Its absolute maximum continous 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.
