Signal converters & Isolators
Temperature Converter PXT-10/11
DESCRIPTION
Temperature converter for converting a temperature to an analogue process signal. The temperature converter has an Pt100/Pt1000 input in two ranges -50-300°C and -50-100°C. A typical application is where temperature measurement is required and when a PLC/ Controller only has analogue inputs.
The temperature range for input and type of analogue output are selected via choice of terminal - see connection diagram.
Features
• Pt100/Pt1000 probe input with/without compensation for cable resistance in two ranges -50 to 300°C and -50-100°C .
• Output 0-10VDC/2-10VDC/0-20/4-20mA - selected via terminals.
• Output offset and gain adjustable ±5%.
• LED indication of input less than 5%.
• Galvanically isolated supply/output is 3,75kV AC 1 min.
• Operating voltage 24VDC, 24VAC, 115VAC or 230VAC.

ADJUSTMENT
PXT-10/11 is delivered adjusted to offset = 0% and gain = 100%. To compensate for any loss in cables, etc. is it possible to adjust the output signal.
Remove the front cover. The offset (zero) and gain (span) on the output signal can be adjusted +/- 5% of max. signal. Put the cover back on to avoid any accidental adjustment of the relay. See fig. 1.
