6ES7131-6BF00-0CA0 ET 200SP DI 8x24V DC High Feature Digital Input | Siemens

The Original New Siemens 6ES7131-6BF00-0CA0 SIMATIC ET 200SP Digital Input Module is an 8-channel high-feature digital input module for distributed I/O systems in industrial automation. Part of the ET 200SP family, this High Feature (HF) module provides 8 configurable sinking inputs for 24V DC signals (PNP, P-reading), with type 3 characteristics per IEC 61131. Featuring a compact 15 mm width, configurable input delay from 0.05 to 20 ms, and comprehensive per-channel diagnostics, it is ideal for high-performance signal acquisition in space-constrained control cabinets.

Core Engineering Highlights:
8-channel 24V DC sinking inputs (PNP, P-reading) | Type 3 (IEC 61131) | Configurable input delay 0.05–20 ms | Per-channel diagnostics: encoder power supply short circuit, wire break, supply voltage | 15 mm width | BU type A0 compatible | Colour code CC01 | 24V DC nominal (19.2–28.8V range) | 20 mA rated current consumption | 1.5 W typical power loss | IP20 protection | –30°C to +60°C operating (horizontal) | Pulse extension function | Isochronous mode support (250 µs) | I&M data (I&M0 to I&M3)
