Selection Guide
Use the following criteria to confirm the correct terminal module for your application:
- Module width: Confirm your electronic module requires a 15 mm terminal module (check EM datasheet)
- Contact type: TM-E15C26-A1 = 26-pin spring contact; TM-E15C24-A1 = 24-pin screw contact — match to your EM’s connector
- Revision suffix: -0AA0 is the standard commercial variant; -1AA0 denotes ATEX/Ex-rated versions for hazardous areas
- Quantity planning: Order 5-packs (this listing) for new panel builds; single units available for spares — contact us
- Lifecycle status: Verify via Siemens Industry Mall or contact Konmask.com for end-of-life risk assessment

Replacement & Compatibility FAQ
Q: Can I use 6ES7193-4CA40-0AA0 instead of 6ES7193-4CA50-0AA0?
A: In most cases yes — both are TM-E15C26-A1 modules with spring contacts. The -0AA0 suffix is identical across revisions for standard applications. Verify with your IM 151 firmware version if using SIL-rated configurations.
Q: Is this terminal module compatible with ET 200SP?
A: No. ET 200SP uses a completely different terminal module form factor (BaseUnit series). The 6ES7193-4CA50-0AA0 is exclusively for ET 200S.
Q: Can I replace the terminal module without rewiring?
A: Yes — the TM-E series supports hot-swap of the electronic module while the terminal module (and field wiring) remains in place. This is one of the key advantages of the ET 200S architecture.
Q: What is the difference between TM-E and TM-P terminal modules?
A: TM-E modules are for standard electronic I/O modules. TM-P modules are power terminal modules used to inject 24 V DC supply segments. They are not interchangeable.
Q: Do you supply single units or only 5-packs?
A: This listing is for a 5-pack. Single-unit orders are available — contact us at support@konmask.com for a custom quote.
