Schneider 140DDI85300 DISCRETE INPUT MODULE
Overview
140DDI85300 is a dedicated DC discrete input module designed for the Modicon Quantum
automation platform, developed by Schneider Electric (document release date: Mar 9, 2013). As a core
I/O component in industrial automation systems, it specializes in collecting and transmitting discrete
DC signals (10–60 V) from field devices (such as sensors, limit switches, and proximity detectors) to
the Quantum controller, forming a critical link between field-level equipment and the control system.
Its 32-channel design (divided into 4 isolated groups) balances input density and signal isolation,
effectively preventing cross-interference between channels and ensuring stable signal acquisition in
complex industrial electromagnetic environments—this is particularly important for applications
requiring high signal integrity, such as manufacturing assembly lines, process control workshops, and
power distribution systems. The flexible voltage compatibility (12 V, 24 V, 48 V, 60 V DC) allows it to
adapt to diverse field device power configurations, reducing the need for additional signal conversion
modules and simplifying system integration.
Practical design features enhance its usability and maintainability: the local LED indicators enable on-
site personnel to quickly check input status and fault conditions, accelerating troubleshooting; the
standard module format and compatibility with Modicon Quantum racks ensure easy installation and
replacement, while the hot-swappable potential (consistent with platform characteristics) minimizes
system downtime during maintenance.
Compliance with multiple international industrial standards and certifications (CE, UL 508, FM Class 1
Division 2, etc.) enables its deployment across global industrial scenarios, including general
manufacturing, oil and gas, chemical, and water treatment industries. Additionally, its sustainability
attributes (RoHS/REACh compliance, Green Premium status) align with modern industrial
environmental protection requirements, supporting long-term stable operation while reducing
environmental impact.
In summary, 140DDI85300 combines high reliability, flexibility, and environmental adaptability,
making it a cost-effective and trustworthy discrete input solution for Modicon Quantum-based
automation systems, effectively meeting the demand for accurate and stable discrete signal
acquisition in medium to large-scale industrial control applications.
Specifications
140DDI85300 is a DC discrete input module under the Modicon Quantum automation platform, with
32 discrete input channels divided into 4 channel groups. Its logic input type is positive (sink), and the
input voltage limits range from 10 V to 60 V DC, with specific input current requirements matching
different voltages: 1–5 mA DC for 60 V, 2–15 mA DC for 48 V, 6–30 mA DC for 24 V, and 5–10 mA DC
for 12 V.
For voltage state guarantees, state 1 (active) is ensured within 9–12 V (12 V ±5%), 45–60 V (60 V
±20%), 34–48 V (48 V ±20%), and 11–24 V (24 V ±20%); state 0 (inactive) is guaranteed within 0–5 V
(24 V ±20%), 0–12.5 V (60 V ±20%), 0–10 V (48 V ±20%), and 0–1.8 V (12 V ±5%), while the absolute
maximum voltage it can withstand is 75 V.
In terms of functional performance, the module requires 2 input words for addressing, has a response
time of 4 ms for switching between state 1 and state 0 in both directions, and a maximum switching
frequency of ≤100 Hz. Isolation performance includes 2500 Vrms DC isolation between channel
groups and the bus (for 1 minute) and 700 Vrms DC isolation between different channel groups (for 1
minute). Power dissipation follows the formula "1 W + (0.62 × number of active input points)", and it
requires a bus current of 300 mA.
Local signalling is achieved through 32 green LEDs (indicating input status), 1 red LED (indicating
external fault detection), and 1 green LED (indicating bus communication presence). The module
adopts a standard format, weighs 0.295 kg, and is marked with CE certification.
Environmentally, it complies with CSA C22.2 No 142 and UL 508 standards, holds C-Tick and FM Class
1 Division 2 certifications, and resists electrostatic discharge (8 kV air, 4 kV contact, conforming to IEC
801-2) and electromagnetic fields (10 V/m at 80–2000 MHz, conforming to IEC 801-3). It operates in
an ambient temperature range of 0–60 °C, stores at -40–85 °C, tolerates 95% relative humidity
(without condensation), and is suitable for operating altitudes ≤5000 m.
In terms of sustainability, it is a Green Premium product, compliant with RoHS (since 0901, with
Schneider Electric’s declaration of conformity) and REACh (no SVHC exceeding the threshold), with
an available product environmental profile for download and no specific recycling operations required
at the end of its life. The contractual warranty period for this module is 18 months.
