The central controller rack must contain the matching IM 460-0 sender. Connect them using the 468-1 interface cable. Set a unique rack number (0-21) via the address switch on the module. Install a termination plug on the last IM 461-0 in the chain. This setup allows you to place communication processors (CP) or function modules (FM) in this remote rack.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eWhat's Included:\u003c\/b\u003e 1 x Siemens IM 461-0 Receiver Interface Module (6ES7461-0AA01-0AA0).\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e The matching central sender (IM 460-0), interface cables (468-1), termination plug, and a separate power supply for the expansion rack are required and sold separately.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOur Guarantee:\u003c\/b\u003e This product is covered by a full \u003cb\u003e12-month warranty\u003c\/b\u003e.\u003c\/p\u003e\n\u003ch3\u003eFast Global Shipping\u003c\/h3\u003e\n\u003cp\u003eWe ensure prompt delivery worldwide via \u003cb\u003eFedEx, UPS, and DHL\u003c\/b\u003e.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eWhat is the key advantage of IM 461-0 over IM 461-1?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe IM 461-0 extends the C-Bus, allowing communication (CP) and function (FM) modules in the expansion rack. The IM 461-1 does not extend the C-Bus, so only I\/O modules are allowed in its expansion rack.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDoes this module power the expansion rack?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNo.\u003c\/b\u003e The IM 461-0 does not transfer power from the central rack. You must install a separate power supply module (PS) in the expansion rack to power all the modules within it.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow many of these expansion racks can I add?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYou can connect up to \u003cb\u003e21 expansion racks\u003c\/b\u003e using the IM 460-0\/IM 461-0 pair, which is significantly more than the 4-rack limit of the IM 460-1\/461-1 pair.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat is the termination plug for?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe termination plug (6ES7461-0AA0-7AA1) must be installed on the last IM 461-0 receiver module in the daisy-chain. It ensures proper electrical termination of the bus signals to prevent reflection and communication errors.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I use a longer cable than 5 meters?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The maximum permitted cable length between the first and last interface module in a chain is 5 meters when using the IM 460-0\/461-0 pair. Exceeding this can cause data corruption.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
