Siemens 6ES7212-1BE40-0XB0 SIMATIC S7-1200 CPU 1212C AC/DC/Relay 8DI/6DO/2AI Programmable Logic Controller

The Siemens 6ES7212-1BE40-0XB0 CPU 1212C is a compact SIMATIC S7-1200 controller with AC/DC/relay power supply, integrated 8 DI, 6 relay DO, and 2 AI, 100 KB work memory, and a single PROFINET interface for PLC-to-PLC and PLC-to-HMI communication. Relay outputs switch up to 2 A resistive load, and the supply accepts 85 to 264 V AC at 47 to 63 Hz.

Selection Notes

The relay digital outputs on this AC/DC/relay variant switch either AC or DC loads directly up to 2 A, which removes the need for external interposing relays when driving small contactor coils or pilot lamps - the DC-only transistor-output CPU variants can't do that. Onboard 8 DI/6DO/2AI plus 3 communication module slots covers small standalone machines without an expansion module; add an SM signal module only when I/O count exceeds the onboard 16 points. The single PROFINET port and OPC UA server support direct HMI and SCADA connection without a separate communication processor.

Applications

Standalone machine control, small process skids, and PLC-to-HMI/SCADA applications needing relay-switched AC or DC outputs and PROFINET-based supervisory communication.
