50/60Hz, max 5 VA
Optional: 20...27VAC/VDC ± 10%
50/60Hz, max 5 VA
Available thermocouples:
J, K, R, S,T, C, D, B, E, L, U, G, N,
Pt20Rh-Pt40Rh
ITS90 or custom linearization
Maintain polarity
For extensions, use a compensated
cable suitable for the type of TC used
linear input voltage
60 mV (Ri > 70kΩ
1 V (Ri > 15kΩ
Linear input in direct current
0/4...20mA, Ri = 50 Ω.
Linear input in direct voltage
5 V, 10V (Ri > 30kΩ
Attention:
with this type of connection the line resi-
stance can introduce measurement error,
we recommend that you use wires of ade-
quate cross-section.
The resistance of the three wires must be
equal, and less than 20 ohm.
