External contact connection.
Pins 13 and 14 of the J1 connector are used.
The release voltage across pins 13 and 14 is approx. 5 V maximum, and the short
circuit current is approx. 500
μ
A maximum. (The internal circuit is pulled up to 5 V
through 10 k
Ω
.)
Use parts with a contact rating of 5 Vdc and 0.5 mA for the external contact.
If multiple units are used under floating conditions and a single external contact is
used to turn on/off the output, isolate the signal to each unit such as by using a relay
on the external contact signal.

For long-distance wiring
When wiring over a great distance, use a small relay and extend the coil side of the
relay.
