Additional Information

Schneider Electric 140ACI04000 Overview

Manufactured by Schneider Electric, the Modicon 140ACI04000 module option processor provides Quantum Series controllers with the high availability and security critical process applications demand. Central to the system is the standby controller with current system status for automatic switchover in the event of a primary controller failure. This means critical processes are unaffected by control system hardware failures. The result – productivity goes up while downtime is minimized.

Configuration and Setup

At the beginning of every primary controller scan, the current register and I/O state table is transferred to the Hot Standby across a high-speed, secure fiber optic communication link. In the event of a primary controller failure, the standby option processor takes control of the system with up-to-date I/O and register status information for a bumpless, controlled transfer with minimal process impact. Critical processes which cannot tolerate any disruption of control are assured a fast, smooth switchover, allowing the 140ACI04000 resolution.


Features / Benefits

  • A single-board Modicon Hot Standby option processor in each controller system improves reliability by eliminating the intermediate supervisor controller.
  • System control transfers occur in either direction increasing system uptime by eliminating the master-slave relationship.
  • Integrity of the user programs are verified and compared in both controllers to ensure high security.
  • High-speed fiber optic communication link between processors minimizes scan impact and improves productivity.
  • Primary I/O state table transfers to the standby controller every scan or in multiple scans providing up-to-date system status and higher system integrity.
  • Software control of Modbus and Modbus Plus ports allows host computer communications to either controller with no custom communication drivers.
  • New configuration extension mode provides greater flexibility in state RAM transfer.
  • An optional ladder logic function block delivers an easy migration path for 984/800 Series hot standby users.
  • The Hot Standby system is compatible with all Modicon TSX Quantum controllers and S908 remote I/O systems for cost-effective system design


Beyond the User Manual

The Modicon Quantum 140ACI04000 analog input module provides 16 channels. Each channel is individually configurable for a 0…25 mA, 0…20mA, or 4…20mA signal. The 140ACI04000 module has broken wire detection in the 4…20mA current mode.

A Quantum removable terminal strip, part number 140XTS00200, is used to allow for easy maintenance. The terminal strip is connected with two screws and can easily be used with any of the Input-Output modules in the Quantum series.

All Quantum I/O modules, including the 140ACI04000, are optically isolated from the bus, ensuring safe and trouble-free operation. This isolation also allows modules to be hot swapped.

Optionally, you can insert mechanical keys between the I/O module and the terminal strip to ensure that the terminal strip to ensure the field wiring and module type are properly matched. Key codes are unique for each module type, and the key kits are shipped with each I/O module.

As an option, modules can be ordered with a conformal coating, which changes the part number to 140ACI04000C. This coating protects the module’s internal circuitry from corrosive gases such as Chlorine, Nitric Oxide, Hydrogen Sulfide, and Sulfur Dioxide.

The Schneider Electric 140ACI04000 comes with a two-year warranty.
