Siemens 6ES7142-4BD00-0AB0 SIMATIC ET 200pro EM 4DO 24V DC/2.0A HF Remote I/O Module

The Siemens 6ES7142-4BD00-0AB0 is a SIMATIC ET 200pro High Feature digital output module with 4 channels rated 2.0 A at 24 V DC, current-sourcing per IEC 61131 type 2. Unlike the standard version, it reports wire-break and short-circuit diagnostics channel by channel, and is suitable for safety-related tripping of standard modules to Performance Level d and SIL 2.

Technical Specifications

Certifications & Standards

• ISO 13849-1 PL d
• IEC 62061 SIL 2

Selection Notes

Pick the High Feature (HF) variant over the standard 4DO module when per-channel wire-break and short-circuit diagnostics matter - a lamp or valve coil failure shows up as a specific channel fault instead of a module-level alert, cutting troubleshooting time on a line with many similar outputs. Substitute values can be configured to hold a defined state if the controller communication drops, which the standard module does not offer. Both variants share the same 2.0 A rating and PL d / SIL 2 safety-related tripping support; choose the standard module only where channel-level diagnostics add cost without adding value.

Applications

Actuator control in distributed SIMATIC ET 200pro stations where individual output faults need to be isolated quickly - solenoid valves, indicator lamps, and contactor coils on lines where a channel-by-channel wire-break alarm shortens diagnosis time.
