3RA65 compact starter with IO-Link (reversing starter)

Features
The 3RA65 compact starter (reversing starter) with IO-Link is made up of the following
components:
● Reversing starter
● Two removable main circuit terminals
● Two 6-pole control circuit terminals (Type A/B)
(Terminal A: L+, C/Q, L-, A2-, A1+/Y1, Y2
● Two slots for optional external auxiliary switch blocks (2 NO contacts, 2 NC contacts or
1 NO contact + 1 NC contact)
Control takes place via IO-Link.
Direction of rotation interlock
The operating mechanisms for the reversing starter's directions of rotation are interlocked.
This precaution prevents the operating mechanisms for direction of rotation 1 and direction
of rotation 2 from being activated simultaneously, which would result in a short circuit.
Operating mechanism interlocking is implemented on both a mechanical level (against shock
loads) and an electrical level (against incorrect activation).
Note
If direction of rotation 1 and direction of rotation 2 are triggered simultaneously, the compact
starter signals a group error and switches off.
