I/O Rack Parts of the H-S81-HS System
2.3.1 S81-E2001-1
Description
This module includes the thirteen modules and the rack controller. Module-field device connections
are carried out using flat cables, with the relevant termination module, from the DIN bar. Using this
bus, systems with redundant I/O modules are not possible.
Technical Features
Internal connections
20-pin flat cables are used in this case to connect the rack to the termination module. Flat cable
maximum length is 5 meters. The type of termination module and the relevant connections depend
on the type of module to be terminated. Field devices, in this case, can be easily disconnected by
simply disconnecting the flat cables from the termination modules.
