The Siemens 6ES7131-6BF00-0CA0 is a SIMATIC ET 200SP High Feature digital input module with eight 24 V DC sink inputs. It accepts a 19.2 to 28.8 V DC supply, consumes 20 mA rated and up to 39 mA maximum, and provides eight short-circuit-protected 24 V encoder-supply outputs. Configurable input delay ranges from 0.05 to 20 ms, while isochronous operation is supported at 250 µs. Channel diagnostics cover sensor-supply short circuit, wire break, supply voltage, and channel faults. The 6ES7131-6BF00-0CA0 supports precise distributed signal acquisition and maintenance diagnostics.

Collects eight 24 V DC sensor signals in compact ET 200SP stations installed near production equipment.

Monitors guards, presence sensors, limit switches, station states, and material-flow signals.

Acquires discrete valve, pump, pressure-switch, level-switch, and alarm signals in modular utility systems.

Uses per-channel diagnostics to accelerate troubleshooting of sensor supply, wiring, and field-signal faults.

Supports isochronous operation and short input delays for coordinated automation tasks.

Restores High Feature digital-input capacity during exact-model replacement and control-system maintenance.
