6ED1055-1HB00-0BA2 New Original Siemens LOGO! Plc Programming Controller module

2. Key Selling Points

1. High-Performance Communication Processor: A signal board (SB) for the Siemens S7-1200 PLC, specifically designed to enhance industrial communication with two independent RS485 serial interfaces, significantly increasing the PLC's connectivity to multiple devices.
2. Dual Independent Serial Ports: Features two fully independent RS485 interfaces that can simultaneously connect to different types of serial devices (e.g., drives, instruments, HMIs), each with separate protocol and parameter settings, enabling parallel data exchange and improving system efficiency.
3. Support for Industry-Standard Protocols: Both ports support MODBUS RTU (master/slave mode), ensuring compatibility with a wide range of industrial field devices for fast and seamless integration into existing automation systems.
4. Plug-and-Play, Space-Saving Design: Designed as a compact signal board that plugs directly into the front-mounted SB slot on the S7-1200 CPU—no additional wiring or power required. Preserves the right-side expansion slots, maximizing panel space utilization.
5. Flexible Networking & High Expandability: Ideal for complex applications requiring simultaneous communication with multiple serial devices (e.g., multi-drive control, data acquisition systems), greatly enhancing communication flexibility and scalability without increasing system footprint.
