Common Applications
Product Precautions
The 6ES7216-2BD23-0XB0 is a compact CPU (CPU 226) featuring 24 DC inputs and 16 relay outputs, integrated into a robust, high-density industrial design with 120/230V AC supply.
- Two independent RS-485 communication ports
- 24 inputs and 16 outputs
- 6 independent high-speed counters
The 6ES7216-2BD23-0XB0 supports connection to up to 7 expansion modules, increasing the number of I/O points to 248, and is compatible with thermocouple and RTD modules to adapt to complex process control. The system has six built-in 32-bit high-speed counters, supporting pulse capture up to 30kHz. Combined with powerful PID closed-loop regulation, it can achieve high-performance motion control applications such as material length cutting, conveyor belt synchronization, and speed monitoring.

Packaging Machinery
Quantitative feeding and thermal sealing control of Vertical Form Fill Seal (VFFS) machines.
Water Treatment
Controls pump start/stop, automatic valve switching based on liquid levels, and backwashing.
Printing Industry
Coordinates registration across color units, paper tension detection, and drying heating control.
Paper Making Industry
Controls pulp consistency, pulper sequential interlocking, and speed-chain control of each paper machine section.
Plastics and Rubber

Energy and Small-Scale Power
Controls the automatic startup, grid-connection switching, and parameter monitoring of small diesel generator sets.
When maintaining and using the 6ES7216-2BD23-0XB0, ensure correct AC 220V power supply wiring to prevent burnout. Since its relay outputs have a limited lifespan and slower response, use electromagnetic isolation for high-frequency switching. As internal capacitor/EEPROM aging in older units can cause program loss, regular backups are essential. Additionally, since this PLC has been discontinued for years, plan early for spare parts or upgrades to the S7-1200.

Technical notes
The 6ES7216-2BD23-0XB0 functions as an integrated control terminal within the Siemens programmable logic controller architecture, driven directly by a wide-range 85V AC to 264V AC power supply with a rated power consumption of 11 W and a maximum inrush current limited to 20 A. This hardware onboard integrates 24 channels of 24V DC digital inputs (with a typical current of 4 mA per channel) and 16 channels of relay outputs (with a maximum rated load current capacity of 2 A per point), alongside a built-in 24 KB program memory, a 10 KB user data memory, and an internal hardware real-time clock chip. For communication and hardware expansion, the module integrates 2 independent RS-485 physical ports supporting PPI, Modbus RTU, and Freeport protocols, while permitting the direct cascade of up to 7 expansion modules via its right-side dedicated backplane bus; the entire assembly supports standard 35mm DIN rail snap-on or screw rigid mounting, and operates reliably under non-condensing environments within a temperature range from 0°C to 55°C.
