Siemens 6ES7143-4BF00-0AA0 SIMATIC ET 200pro EM 4DIO/4DO 24V DC/0.5A Remote I/O Module

The Siemens 6ES7143-4BF00-0AA0 is a SIMATIC ET 200pro combination module with 4 fixed digital outputs plus 4 channels that can be parameterized as either input or output, all rated 24 V DC at 0.5 A. It is suitable for safety-related tripping of standard modules to Performance Level d (Category 3) and SIL 2.

Technical Specifications

Certifications & Standards

• ISO 13849-1 PL d
• IEC 62061 SIL 2

Selection Notes

The 4 parameterizable DIO channels are what separate this module from a fixed 4DO or 8DO card: each of the 4 can be configured as input or output independently, so one module covers a mixed sensor/actuator station slot without dedicating a second module to a handful of extra inputs. Outputs are split into 2 load groups of up to 2 A each, a limit to check when wiring several 0.5 A loads per group. Because it is suitable for safety-related tripping of standard modules to PL d / SIL 2, a fail-safe CPU can switch a standard actuator through this channel without a dedicated F-DQ module. The connection module IO 6ES7194-4CB50-0AA0 must be ordered separately to complete the backplane slot.

Applications

Mixed digital I/O in distributed SIMATIC ET 200pro stations where a slot needs both extra sensor inputs and low-current actuator outputs - proximity switches paired with pilot lamps or small solenoids on the same module.
