6ES7215-1BG40-0XB0 New Original Siemens S7-1200 Plc Programming Controller module

2. Key Selling Points

1. Integrated 18DI + 12 Relay Outputs – Abundant Onboard I/O:Built-in 18 digital inputs and 12 relay outputs, offering one of the highest onboard I/O counts in the S7-200 SMART series, ideal for medium-scale machines with reduced need for expansion modules.

2. Relay Outputs – Compatible with AC & DC Loads:Electromechanical relay contacts (dry contacts) can switch both AC and DC loads (up to 250V AC / 30V DC), directly driving contactors, solenoids, lamps, and small motors without additional relays.

3. Large Memory Capacity – Handles Complex Programs:Provides 30 KB program memory and 20 KB data memory, capable of running complex logic, data processing, and communication tasks for multi-step control applications.

4. Expandable with Up to 7 Modules – High Scalability:Supports up to 7 signal modules (AI, AO, DI, DO, communication, etc.), enabling a maximum of 128 I/O points, suitable for complex system integration and future upgrades.

5. Supports MODBUS RTU Master/Slave – Enables Device Networking:Integrated RS485 port supports MODBUS RTU protocol, allowing the CPU to act as a master polling drives/meters or as a slave communicating with HMIs and SCADA systems.
