must be used with the IM461-4 (6ES7461-4AA01-0AA0) receiving module, and only supports P process bus transmission
Origin: Genuine German Import (Made in Germany)
Maximum transmission distance: up to 605 meters, suitable for distributed IO deployment in remote control cabinets on-site
Expansion Capability: The single IM460-4 module features two expansion interfaces, with each interface supporting up to 4 cascaded expansion racks. A single module can drive a maximum of 8 ER remote expansion racks. A single CPU can host up to 6 IM460-4 modules, enabling the system to support up to 21 expansion racks in total
Bus Specification: Supports only the P process bus (IO process image data), does not support the K communication bus, and cannot achieve cross-rack S7 global data or high-speed communication between PLCs
Power supply requirements: Powered by the S7-400 main rack backplane at 5VDC; all remote expansion racks must be independently powered with a PS407 series power module and cannot draw power from the main rack bus
Hardware Interface: 2 expansion bus interfaces (X1, X2), supporting cascading of multiple IM461-4 receiver modules respectively; equipped with two fault diagnosis LED indicators (INTF, EXTF) for rapid identification of address errors and bus disconnection faults
Cable: Specialized 6ES7468-1BF00-0AA0 extension cable, supports stable long-distance bus signal transmission
Environmental specifications: Operating temperature 0\u00b0C to +60\u00b0C, IP20 protection, compliant with industrial EMC anti-interference standards, suitable for harsh environments in metallurgy, chemical industry, wind power, water treatment, and other fields
Supply Status: Brand new, factory-sealed, ready stock supply, 12-month warranty, supports global bulk export spare parts supply<\/p>\n","protected":false},"excerpt":{"rendered":"
