CTI 2500-RIO-A RS485 Remote Base Controller
2500-RIO-A RS485 Remote Base Controller
The 2500-RIO-A RS485 Remote Base Controller allows control of a remotely-located CTI 2500 Series® or Simatic® 505 I/O base over a twisted-pair RS485 cable up to 1000m from the CPU.
IMPORTANT NOTE: 2500-RIO-A HAS BEEN MATURED.
IT IS REPLACED BY 2500-RIO-B, WHICH SHOULD BE USED ON ALL NEW DESIGNS.
Features
Replaces Siemens® 505-6851-A and 505-6851-B with no rewiring
Can be used in all currently available CTI and Siemens® 4. 8. 11.and 16-slot bases
Works in 2500-R11-A and 505-6511 redundant bases to provide RBC redundancy
Up to 15 remote bases can be attached to a CPU
Maximum cable distance between CPU and remote base is 1000m
