What the 4-in/4-out split means on a live line
The 3RG9004-0DA00 is a 4-input / 4-output AS-Interface F90 module — a standard slave (ID/ID2 code 0/F) that fits a 35 mm DIN rail inside an IP20 control cabinet. The four PNP inputs (switching level high min 10 V) connect to 2- or 3-wire sensors; the four solid-state outputs sink a combined 6 A total, but each output circuit needs its own 20–30 V DC auxiliary supply (PELV, Class III) via the Combicon plug connector. The AS-Interface cable itself powers the module logic and sensor supply (short-circuit and overload resistant), but the output power comes from that separate 24 V feed — a common trip point for integrators who assume the bus handles everything.
Current budget and the external supply catch
The module draws up to 270 mA from the AS-Interface bus for its own logic and sensor feed. The 6 A total output current comes entirely from the external 24 V DC supply — if that supply is missing or undersized, the outputs sit dead regardless of the bus state. Each output is short-circuit protected and has built-in induction protection, so a downstream solenoid or contactor coil does not need a separate flyback diode. The input side draws 5 mA minimum at signal <1> and max 1.5 mA at signal <0>. The sensor supply from the AS-Interface is short-circuit and overload resistant, which means a shorted sensor lead does not take down the whole module — just that channel.
