1756-of8i

Im migrating a 140 ACO 130 00 analog output module to a 1756-of8i , the thing is that i have connected output without returns (on shneider), is the same connection possible on 1756-of8i?
Thanks before hand, im actually kind of new to this.

No. The 140ACO13000 is a current sinking output module requiring an external loop excitation power supply. The 1756-OF8I is a current sourcing output module that gets it's loop excitation power from the chassis backplane. You need to wire it according to the wiring diagram on Page 188 of the manual.
