Principle of operation
The Pt sensor, resistor, potentiometer connected to the input is sent to
the input of the 24-bit A/D converter through the protection and signal
conditioning stages. The digital signal of the A/D converter is
processed by a microcontroller.
The microcontroller performs signal processing according to the
settings and outputs the signal in the form of a PWM signal for the
output stage. After galvanic isolation, the output stage converts it into
an analog current or voltage signal.
The instrument generates the power supply voltages required for the
input side and the output side from the connected power supply using
a galvanically separated, double-output DC-DC converter.
Power supply
The (PS) can be ordered with two types of power supply:
DT1012: 24 VDC ±10 %
DT1012 PS: 230 V AC/DC ±10 %
3.4. Setting
After the instrument is connected to the power supply — see
6.1. First power on
with factory settings according to chapter —
ready for operation.
A detailed description of the settings can be found in
