6.3 Interface modules IM 460-1 (6ES7460-1BA01-0AB0) and IM 461-1
(6ES7461-1BA01-0AA0)
Function
The interface module pair IM 460-1 (send IM) and IM 461-1 (receive IM) are used for a local
link (up to a maximum 1.5 m in total). A 5 V supply voltage is also transferred with these
interface modules. Please particularly remember the following points:
● The current requirements of the module plugged into the ER must not exceed 5 V/5 A.
● You can only connect one ER per line.
● The modules in this mounting rack are not supplied with 24 V and are not backed up.
● The communication bus is not transferred with the interface module pair IM 460-1 and IM
461-1.
● You must not use a power supply module in the ER.
Note
If you connect an ER via a local link with 5 V transmission, ungrounded operation is
prescribed for the ER (see Installation Manual).
