32-channel 24V DC input slice for ET 200L-SC
The Siemens 6ES7131-1BL10-0XB0 is a SIMATIC ET 200L-SC digital input module providing 32 channels at 24V DC, designed for distributed I/O on a remote backplane.
No official successor or cross-reference exists; the 6ES7131-1BL10-0XB0 is the current ET 200L-SC 32DI offering.
Integration into a distributed I/O rack
The module snaps onto the ET 200L-SC backplane bus, which connects to the PROFIBUS DP or PROFINET network via a bus coupler — the 32 input channels are addressed as four groups of eight in the I/O map. Because it is a 32-channel block, the module occupies a single slot on the backplane, keeping the assembly compact for panels with limited DIN-rail real estate.
