Abstract: This disclosure regards a self-keying system for an input/output (I/O) device. An I/O module mountable on a terminal base exchanges I/O signals with external devices via the terminal base. The I/O module comprises a key, and the terminal base comprises a locking assembly to allow insertion of only compatible I/O modules into the terminal base. The locking assembly comprises parallel slots containing a plurality of lock pins movable in the slots between a biased position and a second position. A blocking member is actuated by the key to block each of the lock pins in their respective position to key the base. A maintaining member maintains the blocking member in the keyed position. After keying, a non-compatible key would be rejected from the locking assembly due to the blocked lock pins. A reset to the unkeyed configuration may be accomplished without the use of tools by actuating the maintaining member.
