Output; Electrical Specifications - PR electronics 2273 Mode D'emploi

For RTD input the min. span is 50°C, for linear resistance 30 Ω. The RTD input
can be delivered as multiples of the main type (e.g. Pt1000). The input can be
reversed so that 0% e.g. is 150°C and 100% is 0°C.

OUTPUT:

Analogue 2-wire current output of 4...20 mA.
Maximum load depends on the voltage supply as
R load = (V supply - 10) / 0.02 [Ω].
