Compatible Replacement & Equivalent Models
When the NTLS01 is discontinued or unavailable, engineers may evaluate the following alternatives. Always verify electrical and mechanical compatibility before substitution:
- ABB NTLS02 – Upgraded termination unit with enhanced channel density; verify backplane compatibility
- ABB NTTL01 – Alternate termination layout for AC800M logic stations
- ABB TB820V2 – ModuleBus Modem Unit, used in adjacent termination roles within AC800M
- Third-party DIN-rail terminal blocks – Custom wiring solutions for legacy retrofit projects (requires engineering review)
Note: Konmask recommends using original ABB part numbers wherever possible to maintain system certification and warranty integrity.

Replacement & Compatibility FAQ
Q: Can NTLS02 directly replace NTLS01?
A: In most cases yes, but verify the backplane slot revision and connector pinout before substitution. Contact ABB or Konmask for a compatibility confirmation.
Q: Is the NTLS01 still in production?
A: ABB has transitioned some AC800M accessories to newer revisions. Konmask maintains stock of both current and legacy variants — contact us for availability.
Q: Can I use a third-party termination unit?
A: Third-party units may function electrically but can void system certifications (SIL, ATEX). We recommend OEM parts for certified installations.
Q: What documentation is available?
A: ABB product manual, wiring diagrams, and revision notes are available upon request with your order.
Q: Do you offer exchange or repair services?
A: Yes. Konmask offers board-level repair and exchange programs for NTLS01 and related AC800M accessories. Inquire via email.
