Current input
The current input can only be implemented in conjunction with an external shunt
(not included in delivery).
Example: a 5
shunt results in 0 — 20mA current input, with a programmed
voltage range of 0 — 100mV.
The accuracy corresponds to the voltage input
plus the inaccuracy of the shunt.
