1 GENERAL DESCRIPTION
The single channel temperature transmitter is part of a family of explosion protected DIN
rail mounting modules that transmit to and receive from an Austdac SILBUS field bus
network. The SILBUS-TX1T can transmit a single temperature value on an independent
valid SILBUS channel.
The single temperature input is designed to work with a standard two, three or four wire
PT100 temperature sensor. The temperature transmitter can be configured to operate on
one of two temperature ranges, -10
o
C to +100
o
C or -20
o
C to +200
o
C. This makes the
SILBUS-TX1T particularly suited to monitoring bearing or similar plant temperatures via the
SILBUS network without any requirements for additional power.
The transmitter is housed within a DIN rail mounting enclosure measuring 45mm (W) x
75mm (H) x 110mm (D). The front panel is located between the two top of enclosure
mounted terminal blocks to provide a clear view of the operation indicating LED. A single
LED is provided to show SILBUS network status.
The SILBUS-TX1T can be quickly and simply configured using a laptop computer running
Hyper Terminal and a small plug in programming adaptor. The single temperature input can
be programmed to any SILBUS channel address. The temperature
input can also have it’s
over range, hysteresis, digital set point alarm channels and analogue transmission protocol
configured by the user.
2 WARNINGS AND PRECAUTIONS
WARNING
The red "RUN/PROG" switch (see Photograph 2) next to the console port connector
should be in the run position (pushed towards console port connector) at all times.
If PT100 has a foil sheath then this should be connected with pin 12 to earth. It
should
not
be connect to return ground pin 10, this pin is allocated for the return current of the
PT100.
If the SILBUS-TX1T is used in a manner not specified by Austdac then the protection
provided by the SILBUS-TX1T may be impaired.
PRECAUTIONS
Only qualified personnel shall install and service the SILBUS-TX1T.
Mains supply fluctuations are not to exceed ±10% of the nominal supply voltage.
