6ES7131-6BH01-0BA0

Automation professionals often face the twin challenges of extracting many sensor signals reliably and fitting modules into constrained cabinet or field-bus spaces. The Siemens 6ES7131-6BH01-0BA0 solves both by delivering 16 independent digital inputs at 24 V DC, in a slender 15 mm-wide footprint that mounts on ET 200SP base units (Type A0) for distributed I/O architectures. With support for I&M0–I&M3 data, wire-break detection and supply-voltage diagnostics, this module gives you visibility into signal health and system status—reducing downtime and simplifying maintenance.

Because it uses the popular ET 200SP platform, you benefit from seamless integration in the engineering environment (e.g., via TIA Portal) and ease of scaling across factories, machine panels or building-automation systems. Compared to older digital input modules that lack diagnostic functions or require wider modules, this unit offers higher channel-density, modern diagnostics and better system transparency—making it a superior choice for OEMs or system integrators. Whether you’re collecting switch/sensor status in an HVAC plant, monitoring safety circuits in a parking facility, or building a distributed fire-service automation network, this module delivers professional-grade performance.
