Potentiometer-type IN
Scale range is configurable: from 1 k
to 100 k
(with parallel
resistor R=330
to connect externally). Excitation current:1 mA.
Input impedance:>5M
Thermocouple-type IN
For TC type: J, K, R, S, T, B, E, N. Input impedance:>5 M
.
Automatic detection if a TC interruption occurs
RTD-type IN
For RTD type: PT100, PT500, PT1000, NI100. Resistance measure
(for 2,3 or 4-wires connection) and wire-resistance measure (for 3,4-
wires connection). Excitation current: 1.1 mA (PT100) and 0.11
mA(PT1000, PT500). Automatic detection if a wire or RTD
interruption occurs
Millivoltmeter-type IN
Scale range is configurable: from -10 mV to 80 mV. Input
impedance:>5 M
