Pt100 RESISTANCE, TRANSMITTER RESISTANCE AND THERMOELECTRIC VOLTAGE
CONVERTER WITH AUXILIARY POWER SUPPLY |
Profile: |
| PPN24, PPN230 |
 |
Description: |
- designed for DIN rail mounting
- the auxiliary power supply is isolated from other circuits
- conversion accuracy < 0,3%
- low cost |
The module has been designed to convert the output
of a resistance thermometer, resistance transmitter or thermocouple into a unified output series
(0..10V, 0..20mA, 4..20mA). The resistance sensors may be either two-wire or three-wire connected. The
module can handle output voltages of any standard Platinum or Nickel sensors, carrying out their
temperature-to-resistance transfer function linearization at a time. Two options of the resistance
transmitter circuit connection are available, namely, variable resistance and potentiometer. The
converter can also handle any standard thermocouple voltages. It provides the thermocouple cold
junction compensation at the place of the converter's input terminals. However, no linearization of the
thermocouple voltage vs. temperature response curve is provided. The converter input and output circuits
are not isolated from each other. |

Ordering instructions:
The device has a fixed factory setting. The input signal
type and range cannot be changed. The output setting is fixed, too. This information must therefore
be included in your purchase order.
Your purchase order should include: converter type, input
signal type and range, output signal type and range, number of pieces. Special requirements must be
discussed with us beforehand.
