- Description
The Siemens 6ES7138-7AA00-0AA0 is a reserve module for the SIMATIC ET200iSP intrinsically safe remote I/O station, ATEX-approved for hazardous areas per marking II 2 G Ex ib IIC T4 Gb I M2 Ex ib I Mb. It occupies an unused station slot, connects to the station's DC supply, and has no active inputs or outputs.

Selection Notes
This is a passive reserve module, not an active I/O channel: it fills an unused slot on an ET200iSP intrinsically safe station so the station's slot count and addressing stay fixed for later expansion with a live I/O module. The Ex ib IIC T4 Gb I M2 Ex ib I Mb marking and KEMA 04 ATEX 1251 certificate mean it is rated for the same hazardous-area installation as the rest of the ET200iSP station, so it can be used in the intrinsically safe zone without a separate non-Ex approval check.
Applications
Reserves a slot in an ET200iSP intrinsically safe I/O station for future channel expansion, keeping the station's module layout and addressing unchanged until an active I/O module is installed in its place.
