The backplane expander sits between Quantum racks, carrying the bus signals from one chassis to the next. It is a passive accessory — no addressing, no configuration, no power draw beyond the bus itself. The conformal coating (Humiseal 1A33 per similar Quantum accessories) protects against moisture and airborne contaminants in cabinet environments. Compatibility is limited to the Modicon Quantum automation platform.
Applications
Used in Modicon Quantum PLC cabinets where the local rack has run out of slots and a second or third chassis must be added. Common in large process control systems, water treatment plants, and material handling lines that require more I/O than a single rack can hold.
Compliance
The 140XBE10000C is listed under California Proposition 65. No RoHS, REACH, UL, or IEC certificates are included in the available documentation.
