140CHS21000 Modicon Quantum Schneider Electric Hot Standby Kit

Configured for hot standby synchronization and redundant controller transfer in Modicon Quantum systems, the Schneider Electric 140CHS21000 (140CHS21000 Hot Standby Kit) provides direct physical execution. It operates from a 24 VDC supply, consumes 15 W, supports standby transfer in less than 100 ms, and incorporates communication interfaces for redundant control system operation and diagnostics.

Suffix Breakdown & Model Matrix

The supplied documentation identifies 140CHS21000 as a single catalog number. No official suffix or ordering code subdivision is specified; therefore, no suffix matrix can be derived.

Hardware Specifications

Firmware Flash Compatibility

The 140CHS21000 is intended for redundant controller architectures within the Modicon Quantum platform. During deployment, firmware revisions of the primary and standby controllers should be verified for compatibility before commissioning. Matching firmware versions help maintain synchronization during redundancy management and standby transfer operations. The module communicates through the Quantum backplane while supporting external Ethernet and serial communication interfaces for system integration.

Frequently Asked Questions

Q: Does the 140CHS21000 support hot replacement while the system remains operational?

A: The supplied specifications identify the module as a hot standby kit but do not explicitly state hot-swap capability. Replacement procedures should follow the applicable Modicon Quantum maintenance documentation and site lockout requirements.

Q: What is the standby transfer time during controller switchover?

A: The specified transfer time is less than 100 ms under supported redundant operating conditions.

Q: Which communication interfaces are available on the module?

A: The hardware supports Ethernet communication together with RS-232 and RS-485 serial interfaces. It is compatible with Profibus DP and Modbus fieldbus networks.

Field Installation Guidelines

• Install the module on a properly grounded DIN rail according to the Modicon Quantum system layout.
• Verify that the external power supply provides a regulated 24 VDC source before energizing the equipment.
• Maintain separation between communication cables and high-voltage power conductors to minimize electromagnetic interference.
• Connect cable shields according to the site’s grounding practice and avoid multiple shield grounding points unless specified by the system design.
• Confirm firmware compatibility between redundant controllers before enabling hot standby operation.
• Verify LED status indicators after power-up to ensure normal communication and synchronization prior to placing the redundant system into service.
