TCG140_R1.1 – May 2018

Page 6

5.2.1.

Power supply connection

TCG140 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
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.

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 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 TCG140 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:

It is strongly recommended to use only UTP/FTP cables and keep total cable length up to 30m.
Although functionality has been achieved in the longer distance, we cannot guarantee error-free
operation over mentioned wiring length. We recommend reading Maxim’s 1-Wire tips at
http://www.maxim-ic.com/app-notes/index.mvp/id/148.

We guarantee proper operation only with Teracom 1-Wire sensors.

5.2.3.

RS-485 interface

RS-485 is a standard for serial communications systems defined by Telecommunications Industry
Association (TIA) and Electronic Industries Alliance (EIA). Implementing the standard,
communication systems can be used effectively over long distances and in electrically noisy
(industrial) environments.

The maximum number of sensors (1-Wire or RS-485) connected to TCG140 is 8.

The device supports temperature and humidity-temperature sensors.

MODBUS RTU protocol specifies that address of the device should be between 1 and 247. The
user should take care of appropriate address settings.

For multi-sensors systems “daisy-chained” (linear topology) should be used:
