DIAS I/O System
The DIAS component series is the "classic" among the SIGMATEK I/O systems. A DIAS I/O station consists of a terminal module mounted on a DIN rail and a snap-on function module.
The complete field wiring, with 3-wire connection
technology, is integrated directly into the terminal module. No additional connector terminals are there
fore needed. The function module can be easily
exchanged without having to remove the field wiring. Through direct termination on the module using initiator terminals, connection costs are saved.
