More Information

Overview Manuals Input Groups Wire Supervision Diagnostics Rack Installation

Features:

  • Thirty-two supervised 24 V DC inputs
  • Four positive-logic groups of eight channels
  • Broken-wire reporting through diagnostic registers
Schneider Electric 140DSI35300 places thirty-two supervised field inputs into one Modicon Quantum rack slot.

Four groups of eight channels organize the 24 V DC input wiring on 140DSI35300 and keep group connections distinct.

A shunt-resistor path lets 140DSI35300 distinguish an open field switch from a broken conductor and route that fault to diagnostic registers.

The Schneider Electric 140DSI35300 Modicon Quantum Supervised Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Input Groups

  • Channel Count: 140DSI35300 accepts thirty-two discrete inputs.
  • Grouping: Channels are divided into four groups of eight.
  • Logic: Each group uses positive 24 V DC input logic.

Wire Supervision

  • Open Switch: A shunt resistor maintains supervision current while the field switch is open.
  • Current Threshold: At least 0.15 mA indicates an intact open circuit.
  • Broken Conductor: Current below the threshold is treated as a field-wire interruption.

Diagnostics

  • Normal Data: Input states remain available in the ordinary mapped input words.
  • Fault Data: Broken-wire information is mapped separately.
  • Registers: 140DSI35300 uses diagnostic registers 3 and 4 for the fault bits.

Rack Installation

  • Slot Width: 140DSI35300 occupies one 40.34 mm Quantum slot.
  • Module Height: The single-slot housing is 250 mm high.
  • Module Depth: The installed depth is 103.85 mm.
Description
Schneider Electric 140DSI35300 is a Modicon Quantum supervised discrete input module that brings thirty-two 24 V DC field signals into the Quantum controller as four groups of eight positive-logic inputs.

Each field switch connected to 140DSI35300 uses a shunt-resistor path that maintains at least 0.15 mA when the switch is open. The module interprets current below that threshold as an interrupted field connection instead of a normal open input.

Broken-wire states from 140DSI35300 are mapped into dedicated diagnostic registers 3 and 4, keeping wiring supervision separate from the normal input-state data. Its single-slot Quantum housing fixes the module footprint at 250 mm high, 40.34 mm wide and 103.85 mm deep.

Technical notes
Schneider Electric 140DSI35300 groups 32 supervised 24 V DC inputs as four banks of eight. Broken-wire conditions are reported separately from normal input states.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When an open field switch and a broken wire look alike, how does Schneider Electric 140DSI35300 separate the two conditions?
Schneider Electric 140DSI35300 expects the shunt path to keep at least 0.15 mA flowing through intact open-field wiring; lower current is treated as a broken connection.
Which registers should the controller read for Schneider Electric 140DSI35300 wiring faults?
Broken-wire indications from Schneider Electric 140DSI35300 are mapped to diagnostic registers 3 and 4, separate from the ordinary discrete input-state data.
How are Schneider Electric 140DSI35300 field channels divided at the module boundary?
The 32 supervised points on Schneider Electric 140DSI35300 are organized as four groups of eight positive-logic inputs, so wiring review should follow the group allocation.
Before landing a 24 V signal, what logic convention must be respected on Schneider Electric 140DSI35300?
Schneider Electric 140DSI35300 uses positive logic: the field circuit presents the positive 24 V DC signal to an input while the supervised return path preserves wire monitoring.
Why must normal input data and supervision data be handled separately for Schneider Electric 140DSI35300?
Schneider Electric 140DSI35300 keeps process on/off states in the normal input path and reports broken-wire conditions through dedicated diagnostics, preventing an open command from being mistaken for a cable fault.
