DSP24A1/D - VTPrincips
DSP24A1/D
Display unit for analogue input
signal from transmitter
DSP24A1/D is a display instrument showing the readings from a transmitter. The display unit shows
the readings for pressure, temperature, humidity, air velocity etc.
* Input signal 0...10V or 4...20mA
* Distinct LED display
* Adjustable for different ranges
* Easy to use
* Galvanically separated input
* Supply voltage 24 V AC
Function
DSP24A1/D is connected to an analogue signal from
a transmitter and shows the reading.
The display unit is built into a standard casing for
DIN rail mounting and has all settings easily
accessible on the front.
Input signal
The unit can be connected to a 0...10V or 4...20mA
input signal. The input signal is set by means of an
operating switch .
Range
The required range is set by means of the operating
switches on the front. The following ranges can be
set; 0...10, 0...20, 0...40, 0...50, 0...100, and 0...200.
By activating the decimal point the following ranges
can also be obtained; 0...1.0, 0...2.0, 0...4.0, 0...5.0,
0...10.0 and 0...20.0.
The unit of measurement is presented by means of a
label which is placed on the front below the display
window.
The following labels are supplied; °C, Pa, kPa, mBar,
Bar, %RH, ppm (x1000).
Galvanically separated input
The input for the input signal is galvanically separated
from the supply voltage thus making it possible to
connect the signal input in series with a two wired
transmitter with 4...20mA output signal.
Supply voltage
The unit is supplied by 24V AC.
The supply voltage is galvanically separated from the
signal input by a built-in transformer.
Each measuring range corresponds to input signal
0...10V or 4...20mA.
