2. Declaration of Conformity
The device was tested according to the applicable standards.
Conformity was proofed. The declaration of conformity is
available at the manufacturer BTR NETCOM GmbH.
Notes Regarding Device Description
These instructions include indications for use and mounting of
the device. In case of questions that cannot be answered with
these instructions please consult supplier or manufacturer.
The indicated installation directions or rules are applicable to
the Federal Republic of Germany. If the device is used in other
countries it applies to the equipment installer or the user to
meet the national directions.
Safety Instructions
Keep the applicable directions for industrial safety and preventi-
on of accidents as well as the VDE rules.
Technicians and/or installers are informed that they have to
electrically discharge themselves as prescribed before installati-
on or maintenance of the devices.
Only qualified personnel shall do mounting and installation
work with the devices, see section “qualified personnel”.
The information of these instructions have to be read and un-
derstood by every person using this device.
Symbols
Warning of dangerous electrical voltage
Danger
means that non-observance may cause risk of life,
grievous bodily harm or heavy material damage.
Qualified Personnel
Qualified personnel in the sense of these instructions are
persons who are well versed in the use and installation of such
devices and whose professional qualification meets the require-
ments of their work.
This includes for example:
• Qualification to connect the device according to the VDE
specifications and the local regulations and a qualification to
put this device into operation, to power it down or to activate
it by respecting the internal directions.
• Knowledge of safety rules.
• Knowledge about application and use of the device within the
equipment system etc.
1. Description
The Modbus module with 8 individually configurable
resistance or voltage inputs is designed for local switching
operations. It is suitable to record resistance or voltage values of
for example passive and active temperature sensors electrical
ventilation or mixing valves, valve positions etc. The inputs are
universally configurable and can be scanned via a Modbus-Master.
Setting of the slave address, bit rate and parity is done with the
two address switches (x1 / x10) on the front. Possible settings
are addresses 00 to 99 and baud rates 1200, 2400, 4800, 9600,
19200, 38400, 57600 und 115200 Bd.
The device does not participate in bus communication if the
address is 00 (reserved for broadcast commands).
