Digital I/O Connectors
The two 6-pin mini-DIN connectors can be used to exchange digital signals with
any external device capable of being controlled through a relay or TTL input. The
two connectors are identical in function.
When the relay is activated, the connection is between Com and N.O.
The power supply cord is used as the main disconnect device. Make
sure the socket-outlet is located near the TC and is easily accessible.
Le cordon d'alimentation principal est utilisé comme dispositif
principal de débranchement. Veillez à ce que la prise de base soit
située/installée près du module et facilement accessible.
Das Netzkabel ist das wichtigste Mittel zur Stromunterbrechung.
Stellen Sie sicher, daß sich die Steckdose nahe am Gerät befindet und
leicht zugänglich ist.
