How to connect external input
(minus common connection of no-voltage contact input type)
A signal is inputted to the signal input circuit by short-circuiting or opening the input terminal and
the COM2 terminal. Short-circuiting is effected by means of a contact (such as a relay or a switch)
or a noncontact (such as a transistor or an open-collector TTL).
How to assemble the connector
1.
Set the connector and screws (two) into the grooves of the case (one side).
2.
Cover with the other case, and fit the cases.
