External I/O connection
Details of signal, see "8-1.External I/O" on page 68.
- How to connect external output (Sink type)
The external output circuit is operated through an open collector. A1(A7) COM1 is the common
terminal. The open collector output capacity is 30mA and the withstand voltage is up to 30V.

Output transistor status
- 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)
