Siemens 6ES7141-4BH00-0AA0 SIMATIC ET 200pro EM 16DI DC 24V Remote I/O Module

The Siemens 6ES7141-4BH00-0AA0 is a SIMATIC ET 200pro digital input module, EM 16DI DC 24V, with 16 sink-type (P-reading) channels and module-level diagnostics. It runs on a 24 V DC supply, has an input delay of roughly 1.2 to 4.8 ms on the 0-to-1 edge, and requires the connection module 6ES7194-4CB50-0AA0 ordered separately.

Technical Specifications

Selection Notes

Diagnostics on this module are module-level rather than per-channel, the trade-off against the 8-input HF variant; pick the 16DI when channel count matters more than isolating a fault to one specific sensor, such as a large I/O rack where wiring density is the priority. Its 16 channels in the same 45 x 130 x 35 mm housing roughly double the input density per slot on an ET 200pro station. The connection module 6ES7194-4CB50-0AA0 must be ordered separately.

Applications

High-density digital sensor wiring on a SIMATIC ET 200pro station where module-level short-circuit diagnostics are sufficient.
