Siemens 6ES7131-6BF00-0DA0 ET 200SP DI 8x24VDC High Speed Module

The Siemens 6ES7131-6BF00-0DA0 is a SIMATIC ET 200SP DI 8x24VDC High Speed digital input module with 8 sourcing/sinking channels usable as standard DI, oversampling inputs, or up to 4 counters at 10 kHz, 32-bit width. It runs on a 24 V DC (19.2-28.8 V) supply, supports isochronous mode with a 125 us minimum bus cycle time, and mounts on an A0 BaseUnit.

Technical Specifications

Selection Notes

The "High Speed" designation and 10 kHz counter channels are what set this apart from a standard ET 200SP DI 8x24VDC module - choose it when the station needs to count encoder pulses or fast sensor edges directly on the input module instead of routing them through a separate high-speed counter card. Isochronous mode support (125 us minimum cycle) makes it usable in PROFINET IRT applications with synchronized I/O, relevant for motion-coordinated digital signals. For pure switching I/O with no counting or timing requirement, a standard (non-HS) DI 8x24VDC module is the lower-cost choice.

Applications

Reads fast digital signals and pulse counts in packaging, conveyor, and material handling stations - encoder pulse counting, part-present sensing at high throughput, and oversampled signal capture on a SIMATIC ET 200SP station.
