MTL RTK 725B Annunciator & Recorder

Fits panel or rack alarm systems where you need modular 2–256 alarm ways plus event recording at 1 ms resolution.

Key advantages

Combined annunciator + recorder — MTL RTK 725B modular alarm and event recording range.
2–256 alarm ways — Modular construction for panel or rack builds.
1 ms event resolution — Event recording per OEM datasheet.
Isolated RS485 + USB config — Communications and configuration path per OEM literature.

Typical applications

Control-room and skid alarm panels needing modular window counts.
Event recording alongside conventional alarm annunciation.
Replacements and expansions of MTL RTK 725B modular systems.

Selection guide

Function — Combined alarm annunciator and event recorder (MTL RTK 725B range).
Channels — Modular construction 2 to 256 alarm ways.
Event recording — Event recording with 1 ms resolution (per OEM datasheet).
Communication — Isolated RS485 communications; USB configuration (per OEM literature).
Supply — Options include 85–264 VAC / wide-range DC supplies (verify order code).
Mounting — Panel / rack modular annunciator system.
Approvals — CE.
Notes — Eaton Crouse-Hinds MTL RTK 725B. Specs summarized from OEM datasheet/catalog; confirm exact module ratings on order code.

Common mistakes

Ordering channel count without locking module types and window sizes for the panel cutout.
Assuming every supply option is on one SKU — 85–264 VAC vs wide-range DC must match the order code.
Skipping event-recorder / SOE need when only window annunciation is required (or the reverse).
Confusing DIN-rail P825 SmartAlarm with this modular 725B panel/rack system.
Treating CE alone as sufficient for hazardous-area projects — confirm area marks on the order code.

When to RFQ / what to tell us

Alarm way count (2–256) and window/module layout.
Whether event recording at 1 ms resolution is required and how events are exported.
Supply (85–264 VAC or wide-range DC) and RS485 / USB configuration need.
Panel vs rack mounting; required marks beyond CE.
Quantity, ship-to country. Compatible with MTL RTK 725B systems — we do not claim authorized-dealer status.

FAQ

Q: How many alarm ways? A: Modular construction from 2 to 256 alarm ways. State the count and window layout in the RFQ.

Q: What event resolution is published? A: Event recording with 1 ms resolution per OEM datasheet.

Q: P825 vs 725B? A: P825 is DIN-rail SmartAlarm (8–32 ch). 725B is the modular panel/rack annunciator + event recorder range. Pick by mounting and channel scale.

Q: What should I send for a quote? A: Way count, supply, recorder need, protocol, marks, quantity. Available for MTL RTK 725B — we do not claim authorized-dealer status.
