More Information

Overview Manuals Architecture Field Wiring Safety Validation Application
  • Use only for the approved non-voted AMS 6300 SIS architecture
  • Label every trip conductor and monitor position before replacement
  • Prove each independent shutdown path after wiring

Emerson A6371/10 is the non-voted backplane used with three A6370 monitors in an AMS 6300 SIS overspeed protection system.

It distributes monitor interconnections and presents separate trip outputs rather than the voted relay arrangement provided by A6371/00.

Before replacement, document every monitor position, terminal conductor, trip circuit, sensor and supply connection, backplane-type setting, bypass and site proof-test requirement.

Availability, condition, price, and shipping time for A6371/10 are confirmed during quotation.

Description
A6371/10 is an Emerson AMS 6300 SIS non-voted overspeed-protection backplane.

It accommodates three A6370 protection monitors and provides separate trip outputs rather than the voted arrangement used by A6371/00.

Match every monitor position and terminal conductor to the approved drawing, then independently prove each trip and reset path before return to service.

Technical notes
The official order code is A6371/10; A6371-10 is only a punctuation/search variant. Weight 0.49 kg excludes the A6352 rack. A6371/00 is a voted backplane and is not a direct substitute.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the key difference between Emerson A6371/10 and A6371/00?
A6371/10 provides non-voted separate trip outputs, while A6371/00 implements the voted arrangement. They are not interchangeable without safety-design review and configuration changes.
Which monitor cards belong on Emerson A6371/10?
The documented AMS 6300 SIS architecture uses three A6370-series protection monitors; confirm whether the system requires A6370D or the PROFIBUS A6370D/DP variant.
Can Emerson A6371/10 be replaced without moving the trip wiring?
Only if every terminal, monitor position and external trip circuit exactly matches the approved drawing. Photograph, label and continuity-check all conductors before removal.
Why can the monitors show RELAY after installing Emerson A6371/10?
The monitor configuration may still declare the voted A6371/00 backplane. Set the documented non-voted backplane type and verify relay wiring before restart.
What terminal checks matter on an Emerson A6371/10 replacement?
Confirm conductor size, 8 mm strip length, ferrules where required, torque, segregation, shield terminations and that no trip contact has been moved to a different channel.
Can Emerson A6371/10 be tested without affecting shutdown circuits?
Not without the approved isolation and proof-test plan. Backplane relay work can directly alter shutdown paths, so bypass authorization and independent verification are required.
How should Emerson A6371/10 be accepted after wiring?
Perform point-to-point continuity checks, confirm monitor positions and backplane type, prove each separate trip and reset path, inspect diagnostics, and document restoration of all safety functions.
