Configuration (Setup Unit Here)
IMPORTANT: DT models have three modes of operation:
1
Dual
Transmitter,
2
Single Transmitter, and
3
Signal Splitter. The
Configuration Screen varies with the Operating Mode selected.
The second screen at left is for Single Transmitter mode, the third
screen at left is for Signal Splitter mode.
The initial Configuration screen returned represents the
connected module’s current configuration and operating mode
before making changes. Otherwise, you could have loaded the
configuration from a saved file, or you may have changed a field.
You can always click
[Get I/O Config] to retrieve the connected
module’s current configuration at any time.
Note that if you make any changes to the configuration indicated,
the only way to preserve the changes is to write them to the
device by clicking
[Send I/O Config] , or to save them to a file by
clicking “ F ile” in the upper left-hand corner of the screen.
NOTE: Note that each channel of these dual transmitter models
has two input paths that differ by the nominal range supported.
For the DT236, the first input path A is at TB1-1/TB3-1 (leftmost
terminal of TB1/TB3) and intended for DC current only. The
second input path B is at TB1-3/TB3-3 (the rightmost terminal of
TB1/TB3) and intended for DC voltage only. For both the DT237
& DT238 models, each input path supports a different range of
DC voltage input for the channel. Your input range selection will
determine which terminal you must wire your input to. Note that
the center terminal is always the channel signal return for both
input paths.
Select the Operating Mode...
The DT transmitters are quite versatile in that they support three
different operating modes: Dual Transmitter, Single CH1
Transmitter, and CH1 Signal Splitter. You can change its mode of
operation at any time to suit your application
Select the Input Type/Range …
Input Type refers to the nominal input range. Different Input
ranges may use different signal paths (see NOTE above). The first
terminal A of a DT236 channel supports DC current (TB1/TB3-1)
of ±20mA, 0-20mA, 4-20mA, 0-11.17mA, and ±1mA. Its third
terminal B (TB1/TB3-3) supports DC voltage ranges of ±0.5V, 0-
500mV. The first and third terminals of the DT237 & DT238
models (TB1/TB3-1 and TB1-3/TB3-3) each support different
nominal DC voltage ranges. Signal return is wired to the middle
terminal between them (TB1/TB3-2).
