ero electronic DPS - Linear Input; RTD (Resistance Temperature Detector)

7
B) Linear input
Input type: See table below
Readout: keyboard programmable between -1999 and +9999.
Linearization: input signal may be linearized by setting up to 9
breakpoints (10 segments) on the input span.
Square root estraction: programmable
Decimal point : programmable in any position.
Burn out: Up scale for 12-60 mV inputs;
down scale for 4-20 mA, 1-5 V and 2-10 V.
It is not detectable for the other ranges.
STANDARD RANGES TABLE
C) RTD (Resistance Temperature Detector)
Input: for RTD Pt100 Ω and Ni 100 Ω, 3 wire connection with °C/°F
selectable by front pushbuttons.
Input circuit: current injection (100 µA).
Line resistance: automatic compensation up to 3 Ω/wire with no
measurable error.
Calibration: according to DIN 43760
Standard ranges: see table
Burn out: up scale or down scale programmable for open circuit of one
or more wires.
