6ES7214-1BG40-0XB0 SIMATIC S7-1200 CPU 1214C

The 6ES7214-1BG40-0XB0 is the Siemens article number for a SIMATIC S7-1200 CPU 1214C.

Compared to the 1212C, the 1214C gives you a significantly higher onboard I/O count, more program memory, and a wide-range AC power supply.

The breakdown of its technical specifications includes:

General Configuration

• Model Type: CPU 1214C AC/DC/Relay (Compact)

• Firmware Line: Native V4.x firmware architecture line.

Power Supply & Voltages

• Supply Power: Line AC voltage (85 V to 264 V AC at 47 Hz to 63 Hz).

• Sensor/Encoder Power Output: Onboard 24 V DC power supply source (outputting 20.4 to 28.8 V DC) to power external sensors or encoders.

Onboard I/O Channels

• Digital Inputs (DI): 14 Inputs (24 V DC, sink/source capable).

  • High-Speed Counters: Supports up to 6 HSCs for fast pulse/encoder inputs.

• Digital Outputs (DO): 10 Outputs (Relay type).

  • Switching Capacity: Max 2 A resistive load; capable of handling up to 30 W DC or 200 W AC lamp loads.

• Analog Inputs (AI): 2 Inputs (Voltage type, range 0 to 10 V DC).

  • Resolution: 10-bit internal.

Memory Allocation

• Work Memory: 100 KB or 150 KB (integrated, non-expandable — exact capacity depends on whether it is running older or the latest V4.x firmware updates).

• Load Memory: 4 MB integrated (expandable using a standard SIMATIC Memory Card).

• Retentive Data Area: 14 KB maximum area for retentive DBs, bit memory, timers, and counters.

Expansion Capabilities

• Signal Modules (SM): Supports up to 8 expansion signal modules (bolted to the right side).

• Communication Modules (CM): Supports up to 3 communication modules (attached to the left side).

• Signal Boards (SB/CB): Supports 1 slot directly on the front faceplate
