S7-200 CPU 224 with 4kWords and relay outputs
The 6ES7214-1BD20-0XB0 is a Siemens S7-200 CPU 224 with 4kWords of program memory, AC power supply, DC inputs, and relay outputs — the classic compact PLC for standalone machine control. It sits in the S7-200 family, which is Siemens' entry-level modular PLC line for small to mid-size automation tasks — think conveyor control, packaging machines, or pump skids where you need 14 digital inputs and 10 relay outputs on a single compact unit. The relay outputs handle up to 2 A per channel at 24 VDC or 250 VAC, so you can drive contactors, solenoid valves, and indicator lights directly without interposing relays — saves DIN rail space and wiring time.
Current production — no obsolescence risk
Quoted to order against the BOM quantity; availability and current pricing confirmed at RFQ through independent distribution channels.
DIN-rail fit and panel integration
Snaps onto 35 mm DIN rail per EN 50022 — standard S7-200 footprint. The AC/DC/RLY variant means you bring line voltage to the L/N terminals, 24 VDC field power to the inputs, and the relay commons connect directly to your load circuits. No external 24 VDC power supply needed for the CPU logic — the onboard AC supply handles that. The relay outputs are isolated per common group, so mixing 24 VDC and 230 VAC loads on the same unit is fine as long as you respect the common wiring.
