5.2.1.
Power supply connection
TCG120-4 is designed to be supplied by adapter SYS1308-2412-W2E or similar, intended for use
in the conditions of overvoltage category II. The power supply equipment shall be resistant to
short circuits and overload in a secondary circuit.
When in use, do not position the equipment so that it is difficult to disconnect the device from
the power supply.
5.2.2.
1-Wire interface
1-Wire is a registered trademark of Maxim integrated products, Inc. It is designed to connect
several sensors over short wiring. It is not suitable for long distances or noisy environments.
The maximum number of 1-Wire sensors connected to TCG120-4 is four.
The device supports all Teracom 1-Wire sensors. Connected sensors are automatically detected
and the appropriate dimension is assigned.
It is strongly recommended to use “daisy
-
chained” (linear topology) for multi
-sensor systems:
