It is strongly recommended to
use only UTP/FTP cables and keep total cable length up to 30 m.
Although functionality has been achieved on longer distance, we cannot guarantee error-free
operation over mentioned wiring length.
We
guarantee proper operation only with Teracom 1-Wire sensors.

Relay connection
The relay contacts are internally connected directly to the terminal connectors. For all relays normally open,
normally closed and common contacts are available.
For loads with higher switchable current/voltage than specified, an external relay should be used.
When mechanical relays switch inductive loads such as motors, transformers, relays, etc., the
current will arc across the relay contacts each time the contacts open. Over time, this cause wears
on the relay contacts which shorten their life. When switching an inductive load, it is
recommended that relay contact protection devices are used.
