What the I/O count means for your panel
The Siemens 6ED1052-1FB00-0BA2 is a LOGO! 230RC logic module with 6 digital inputs and 4 relay outputs — a compact 72 x 90 x 55 mm block that snaps onto DIN rail and handles standalone machine control or small-process sequencing without a full PLC rack. The six inputs accept 115 V AC, 230 V AC, 115 V DC, or 230 V DC directly — no separate power supply module needed for the input side, which simplifies wiring in panels where line voltage is already present. Each relay output handles 10 A resistive or 3 A inductive loads, so you can switch contactors, small motors, or solenoid valves directly without an interposing relay — but the module itself draws 4.6 W max at 230 V AC, so the heat stays manageable inside a sealed enclosure.
Supply voltage and wiring constraints
The module runs on 115/230 V AC (47–63 Hz) or 85–253 V DC, with a typical input current of 80 mA at 230 V AC — the same supply rail powers both the logic and the input circuits, so you only need one feed to the module. Signal thresholds are set for industrial line voltages: a '0' signal is up to 40 V, and a '1' signal starts at 79 V minimum — this gives noise immunity on long field wiring runs common in conveyor or pump stations. The screw terminals accept 2 x 1.5 mm² solid wire or 0.5–2.5 mm² stranded with ferrule, which covers standard panel wiring practice — no special crimp tools needed. There is no internal short-circuit protection on the outputs — external fusing up to 16 A per output circuit is required, a detail that catches first-time LOGO! users who expect built-in protection.
Temperature range and enclosure placement
Rated for -20 °C to 70 °C ambient, the 6ED1052-1FB00-0BA2 survives the nacelle environment — no up-tower swaps needed for winter starts or summer heat soak inside a steel enclosure.
