Siemens 6ES7141-4BF00-0AB0 SIMATIC ET 200pro EM 8DI 24V DC HF Remote I/O Module

The Siemens 6ES7141-4BF00-0AB0 is a SIMATIC ET 200pro digital input module, EM 8DI 24V DC High Feature, with 8 sink-type (P-reading) channels, per-channel wire-break and short-circuit diagnostics, and a parameterizable input delay from 0.5 to 20 ms. It runs on a 24 V DC supply and requires the connection module 6ES7194-4..00-0AA0 ordered separately.

Technical Specifications

Selection Notes

The High Feature (HF) designation is why to choose this module over a Standard-Feature 8DI module: it adds per-channel wire-break and short-circuit diagnostics with a parameterizable 0.5/3/15/20 ms input delay, so a fault is isolated to one sensor rather than reported at module level. The 8 electronically short-circuit-protected encoder supply outputs let 2-wire sensors draw power directly from the module instead of a separate 24 V distribution block. The connection module 6ES7194-4..00-0AA0 must be ordered separately; only the electronic module and bus module are included here.

Applications

Digital sensor and limit switch wiring on a SIMATIC ET 200pro DIN-rail or field-mounted station where per-channel fault isolation to a specific sensor is needed.
