HIRSCHMANN RS20 RAIL SWITCH

There are four basic types of digital output modules: 

1 Supervisory Digital Output Module 2 DC voltage digital output module 3 AC voltage 

digital output module 4 dual channel DC digital output module,

 each digital output module contains three identical separate circuits isolated from each other.

 Each sub-circuit contains an IOP microprocessor that receives its output table from the IOC communication processor on the corresponding main processor. 

All digital output modules, with the exception of the dual-channel DC module, 

use “Quad output voting”, 

which votes on individual output signals just before they are sent to the load. 

This voting circuit is based on a parallel serial path, 

which is passed by a vote of two out of three 

when either a and B, or B and C, or a and C are closed. 

HIRSCHMANN RS20 RAIL SWITCH'S FUCITON IS POWERFUL

The dual-channel digital output module has a single serial channel, 

and the two-for-three voting process acts on each switch separately. 

Quadrilateral output voting circuits provide multiple redundancy for all critical channels, 

ensuring security and maximum utilization.

 The dual-channel output module gives just enough redundancy to ensure safe operation. 

The dual-channel output module is more suitable for critical safety situations 

where low cost is more important than maximum utilization.
