Selection Guide
Use the criteria below to select the correct ET 200S digital output module:
- 4 ch · 24VDC · 0.5A · transistor PNP: → 6ES7138-4DF11-0AB0 ✓ (this model)
- 2 ch · 24VDC · 2A · transistor PNP: → 6ES7138-4DB03-0AB0
- 2 ch · relay · 24VDC/230VAC · 2A: → 6ES7138-4DC01-0AB0
- 4 ch · 24VDC · 0.5A · fail-safe (F-DO): → 6ES7138-4FB03-0AB0
- 8 ch · 24VDC · 0.5A (compact): → ET 200SP 8DO module (requires system migration)
Key selection criteria: channel count → load current → load type (resistive / inductive / lamp) → safety requirements (standard vs. fail-safe) → terminal module availability.

Replacement & Compatibility FAQ
Q: Can I replace 6ES7138-4DF01-0AB0 with 6ES7138-4DF11-0AB0?
A: Yes. The -11- revision is the updated version of -01-. Direct drop-in replacement using the same terminal module and GSD file. No hardware or software reconfiguration required in most cases.
Q: Is the 6ES7138-4DF11-0AB0 compatible with ET 200SP?
A: No. ET 200S and ET 200SP use different mechanical and electrical interfaces. Migration requires replacing the interface module, terminal modules, and updating the hardware configuration in TIA Portal.
Q: What terminal module does this electronic module require?
A: TM-E15S24-01 (6ES7193-4CA30-0AA0). Ensure the terminal module is pre-installed on the DIN rail before inserting the electronic module.
Q: Can this module switch AC loads?
A: No. This is a DC transistor output module (24 VDC only). For AC load switching, use the relay output variant 6ES7138-4DC01-0AB0.
Q: What is the maximum total current for all 4 channels?
A: 0.5 A per channel; do not exceed 2 A total simultaneous load. Refer to Siemens ET 200S manual (A5E00124871) for derating curves.
