Power supply
TCW210-TH is designed to be supplied by adapter SYS1421-0612-W2E or similar, intended for
use in the conditions of overvoltage category II, and prior assessed for compliance with safety
requirements. The power supply equipment shall be resistant to short circuit 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.
6.2.2.
1-Wire interface
1-Wire is a registered trademark of Maxim Integrated Products, Inc. It is designed to connect
several sensors over a short wiring. It is not suitable for long distances or environments with
EMC interference.
The maximum number of sensors (1-Wire or RS-485) connected to TCW210-TH is 8.
The device supports temperature and humidity-temperature sensors. Connected sensors are
automatically detected and appropriate dimension is assigned.
It is strongly recommended to use “daisy-chained” (linear topology) for multi-sensors systems:
