CTI 2500-RBC 901E-2500-RBC Remote Base Controller

2500-RBC (901E-2500-RBC) is a Profibus remote base controller of the classic 2500 series under CTI, specially designed for industrial distributed I/O expansion scenarios. It can directly replace Siemens 505-6870 RBC, enabling CTI 2500 series or Siemens Simatic 505 I/O bases to be connected to the control network as slave nodes complying with the Profibus DP standard. It undertakes the communication transfer and data interaction tasks of remote I/O bases, is compatible with all models of CPUs of CTI 2500 series and Simatic 505 control systems, supports rack-mounted installation, has industrial-grade anti-interference capability, and has no PLC programming function through serial ports. It can seamlessly realize the distributed expansion of remote I/O bases to meet the needs of building remote measurement and control links in industrial sites.​
