ELECTRICAL CONNECTION / EXTERNAL LOAD
External loads must be placed in the negative side of the 2-wire loop. The minimum power supply is
based on the total circuit resistance. The maximum external load (RI max.) for 24 Vdc will be 600 Ω
(Ohm). At higher power supply, the external load can be up to max. 1200 Ω / 36 Vdc.
With a loop resistance of 250 Ω a power supply of at least 17 Vdc must be used.
