140ATI03000C
Schneider Electric
Overview
The Schneider Electric 140ATI03000C is the conformal-coated variant of the eight-channel analogue input module for the Modicon Quantum platform. It draws 280 mA from the backplane and, with its protective coating, is better suited than the standard module to humid, washdown or corrosive environments.
The module fits a single Quantum slot, weighs about 0.3 kg and operates across 0–60 °C ambient with 5–95 % non-condensing humidity tolerance. It carries CE, cUL and FM Class 1 Division 2 approvals and presents channel status through LEDs, following the established Quantum I/O design.
Application & Technical Notes
Electrically the 140ATI03000C matches the 140ATI03000; the C suffix adds conformal coating for harsher duty. Eight analogue inputs provide moderate density at a 280 mA backplane draw, which is easy to accommodate in most rack power budgets. The coating extends service life where the module is exposed to moisture, chemical vapour or dust.
Integration follows standard analogue practice: confirm signal types and ranges, budget addressing words and backplane current, and use shielded, grounded wiring separated from power circuits. Map module diagnostics in the controller so channel faults are detected promptly, and confirm absolute maximum inputs are not exceeded on exposed wiring.
Maintenance & Diagnostics
The 140ATI03000C is low-maintenance. During commissioning, verify each of the eight channels and confirm signal range before the loop is trusted. Keep the rack within 0–60 °C and 5–95 % non-condensing humidity; the coating helps, but condensation should still be avoided.
De-energise the rack before insertion or removal. Because the coating can hide damage, inspect the module visually during shutdowns for cracked housing or overheating. Store spares between −40 and 85 °C in original packaging and recalibrate quality-critical channels at planned intervals.
Sourcing & Procurement
The 140ATI03000C is the conformal-coated version of the 140ATI03000; choose it when the installation faces humidity, washdown or contaminants. Genuine Schneider Electric modules are recommended for new builds and safety-related loops because they retain the original CE, cUL and FM certifications and warranty.
Compatible alternatives may cost less, but verify channel count, isolation, accuracy and approvals before substitution. For long-lead parts, refurbished genuine units from a reputable supplier are generally safer than clones. Buy from authorised distributors where possible and retain serial traceability.
Frequently Asked Questions
What is the difference between 140ATI03000 and 140ATI03000C?
The 140ATI03000C adds conformal coating for humid or contaminated environments; channel count and electrical characteristics are otherwise equivalent.
How many channels and what input type?
Eight analogue input channels for general analogue acquisition in a single Quantum slot.
What backplane current does it draw?
Approximately 280 mA from the Quantum backplane.
What certifications does it hold?
CE, cUL and FM Class 1 Division 2, suitable for designated hazardous-location use within rated conditions.
When should I choose the C variant?
When the module will be exposed to moisture, washdown, chemical vapour or dust that could degrade an uncoated board.
Specifications
The Schneider Electric 140ATI03000C is an I/O expansion module designed for use with Modicon Quantum systems. This module accommodates 8 analog input points and supports thermocouple input with a high resolution of 16 bits.
Description
| Note | The 140ATI03000C by Schneider Electric functions as an I/O expansion module within the Modicon Quantum series. This device integrates eight analog input channels specifically designed for thermocouple measurements. With a resolution of 16 bits, the module ensures that signal precision is maintained for accurate temperature readings. Additionally, the analog inputs utilize a notch filter set at 3 dB for 50/60 Hz and a single pole low pass filter at 20 Hz, which helps mitigate interference and maintain the integrity of analog signals. The module operates with a bus current requirement of 280 mA and exhibits a power dissipation range of 1.5 watts. The update time is set at 1000 ms, ensuring timely data transmission for responsive application performance. Notably, this expansion module does not provide output points, focusing solely on analog input functionality, making it a specialized component for specific needs in control systems. |
