Siemens 6ES7136-6DB00-0CA0 SIMATIC ET 200SP F-DQ 4x24VDC/2A PM HF Fail-safe I/O Module

The Siemens 6ES7136-6DB00-0CA0 is a SIMATIC ET 200SP fail-safe digital output module with 4 short-circuit-protected 24V DC transistor outputs rated 2A per channel, achieving Performance Level e / SIL 3 to ISO 13849-1 and IEC 61508, fitted to BU type A0.

Technical Specifications

Selection Notes

Each of the 4 transistor outputs is individually short-circuit and overload protected, tripping at roughly 3.3A short-circuit / 2.9A overload, well above the 2A rated load, so a single shorted output doesn't force a module-wide shutdown. Open-circuit detection at 8mA lets the module flag a disconnected load even when the output is off, which matters for safety-related outputs where a broken wire needs to be caught before the next demand rather than discovered at the next real stop event. The 4W power loss is noticeably higher than the standard-range ET 200SP I/O modules, a consequence of the internal diagnostics and dual-channel safety switching path needed to reach PL e / SIL 3 - worth accounting for in enclosure thermal budgets when several of these sit side by side in a safety station.

Applications

Fail-safe 24V DC output for E-stop circuits, safety interlocks, and safety contactor/valve coil switching up to PL e / SIL 3 in SIMATIC ET 200SP-based safety stations, typically paired with a fail-safe relay output module for AC or higher-current loads.
