Siemens 6ES74031TA010AA0

Technical Parameters

High-Density Contact Monitoring

Supports 32-channel DC 24V sink/source inputs with individual channel diagnostics, detecting wire-break thresholds <2mA (sink mode) or >22mA (source mode).

Asymmetric Input Filtering

Programmable filter times (0.1/0.5/3/15ms) with ±10% tolerance, featuring independent rising/falling edge configurations per channel group (8 channels/bank).

Galvanic Isolation Scheme

Triple-tier isolation: 500V AC between field/channels, 1500V AC between channels/backplane, and 2500V AC between field/backplane (EN 61131-2 compliant).

Dynamic Load Compensation

Auto-adjusts input impedance from 3kΩ (nominal) to 8kΩ during voltage dips (<18V) to maintain signal integrity, with <5µs compensation latency.

Backplane Power Allocation

Draws 250mA max from 5V logic rail and 80mA from 24V sensor supply, requiring PS 407/PS 405 power supplies in non-redundant configurations.
