140ACI05100SC
Schneider Electric
Overview
The Schneider Electric 140ACI05100SC is a thirty-two-point input module for the Modicon Quantum series, designed for applications that need high analogue channel density with strong noise immunity. It delivers precision conversion at 12-bit or 16-bit resolution and holds accuracy between ±0.1 % and ±0.2 % of full scale, supporting precise measurement tasks across mixed signal loops.
The module is built for harsh environments: channel-to-channel isolation is typically 500 V DC and channel-to-backplane isolation typically 1500 V DC, helping it survive ground loops and transients on long field wiring. It operates from 0 to 60 °C, tolerates 5–95 % non-condensing humidity, and mounts on DIN rail or panel. At 0.91 kg it is a substantial rack component, and the SC designation denotes a specific configuration within the Quantum input family.
Application & Technical Notes
The 140ACI05100SC targets systems where many analogue points must be concentrated in limited rack space. Selectable 12-bit or 16-bit resolution lets integrators trade speed for precision per application, while ±0.1–0.2 % full-scale accuracy is adequate for most monitoring and supervisory control duties. The differential, well-isolated architecture rejects common-mode interference, which is important when transmitters share different references.
The 500 V DC channel-to-channel and 1500 V DC channel-to-backplane isolation figures are the headline reliability features, reducing the risk of a single fault cascading across the rack. Plan for the module's backplane current and addressing requirements, and confirm the SC configuration matches the intended signal types before ordering.
Maintenance & Diagnostics
The 140ACI05100SC is low-maintenance. Commission by checking channel status and confirming each input is within its expected range before the loop is trusted. Keep the rack within 0–60 °C and 5–95 % non-condensing relative humidity, and ensure ventilation around the module is not blocked.
Because thirty-two points share one module, a single failure removes more signals than a smaller module would, so a spare is advisable for critical systems. De-energise the rack before insertion or removal to protect the backplane, and store spares between −40 and 85 °C in original packaging. Recalibrate quality-critical channels against a known source at planned intervals.
Sourcing & Procurement
The 140ACI05100SC is a high-density Quantum input module; confirm the SC configuration and signal types match your design before purchase. Genuine Schneider Electric modules are recommended for new builds and safety-related loops because they retain the original certifications and warranty. Compatible equivalents may cost less, but verify channel count, isolation and accuracy before substituting.
For long-lead or discontinued parts, refurbished genuine units from a trusted industrial supplier are generally safer than clones. Buy through authorised distributors where possible, validate the seller, and keep the manufacturer part number and serial records for traceability and warranty.
