Electrical parameters of ZSP-41 and ZSP-41/2

Two-wire power supply
Power consumption
When switching on in the ZSP-41 isolator, the maximum temporary power
consumption is about 3,5VA (power necessary to start up the internal
converter)

Conversion errors
- basic error (***)
- temperature change effect
- load resistance change effect
- power voltage change effect
(***) ERROR VALUE REFERS TO RANGE SETTING 4...20mA/4...20mA WITHOUT
POWER SUPPLY TO INPUT CONVERTER. WITH OTHER SETTINGS (WITHOUT
ADDITIONAL CALIBRATION) BASIC ERROR IS 0.25% - not applicable to
