IM 460-3 interface module 6ES7 460-3AA01-0AB0

•Transmitter module for central controller

•Without transmission of voltage to the expansion unit

•Cable up to 100 m long

•With K-bus for communication with CPs and FMs in the expan- sion unit

•For connecting as many as 8 ex- pansion units

IM 461-3 interface module	6ES7 461-3AA01-0AA0
Corresponding receiver module
for the expansion unit
UR1 rack	6ES7 400-1TA01-0AA0
for central controllers and expan-
sion units
• 18 slots
• Suitable for redundant power

Expansion units can be used for the distributed expansion of the SIMATIC S7-400. The IM 460-x interface modules are used as the interface for these expansion units.

Restrictions compared to standard I/O modules from the ET 200M range

•No redundant interfacing of expansion units

•No configuration during normal operation

Subracks

The universal racks (UR) are used for SIMATIC PCS 7. They can be used as central racks and as expansion racks. Other racks: see Catalog ST 70.
