A6370D/DP
Emerson A6370D/DP Overspeed Protection Monitor with PROFIBUS DP
Product Overview
The Emerson A6370D/DP is a single-channel overspeed protection monitor designed for the AMS 6300 SIS overspeed protection system. Compared with the standard A6370D, the A6370D/DP version includes a PROFIBUS DP communication interface for compatible industrial automation and monitoring networks.
The module monitors rotational speed signals from compatible eddy-current, Hall-effect, and magnetic variable-reluctance (VR) sensors. It supports overspeed monitoring and related speed measurement functions in critical rotating machinery applications.
The A6370D/DP is suitable for supported installations involving steam turbines, gas turbines, and other rotating equipment where reliable speed monitoring is required as part of a machinery protection system.
The module is designed for installation with a compatible A6371 system backplane in the AMS 6300 SIS rack. Verify the complete model designation, backplane type, firmware revision, and communication requirements before ordering.

Key Features
Overspeed Protection Monitoring
The A6370D/DP monitors rotational speed signals and supports configured overspeed protection functions within the AMS 6300 SIS architecture. Protection thresholds and trip behavior must be established according to the approved system design and application requirements.
PROFIBUS DP Communication
The integrated PROFIBUS DP interface allows the monitor to communicate with compatible automation and monitoring systems. Network configuration, addressing, and data exchange must be set up according to the applicable Emerson documentation.
Multiple Sensor Technologies
The module supports compatible eddy-current, Hall-element, and magnetic variable-reluctance sensors. Sensor selection depends on the machinery installation, trigger-wheel arrangement, and input signal requirements.
Front-Panel Display
The integrated display provides local access to supported measurement and status information, helping maintenance personnel review module operation during inspection and troubleshooting.
Industrial System Integration
The A6370D/DP is designed to operate within the AMS 6300 SIS system using a compatible A6371 backplane. The overall protection system configuration determines how the module participates in machinery protection and trip logic.

vs. /DP
The primary documented difference is the communication interface.
- A6370D: Single-channel overspeed protection monitor with display and USB configuration.
- A6370D/DP: Single-channel overspeed protection monitor with display, USB configuration, and PROFIBUS DP communication.
When replacing a module, check the installed automation network and confirm whether PROFIBUS DP is required. The two variants should not be treated as interchangeable without verifying the system configuration.
Installation and Compatibility
Before purchasing or installing the A6370D/DP, confirm:
- The complete model designation on the module nameplate.
- Compatibility with the installed AMS 6300 SIS system.
- The A6371 backplane type and trip logic arrangement.
- Sensor type and input signal characteristics.
- PROFIBUS DP network requirements and configuration.
- Hardware and firmware revision compatibility.
Overspeed protection equipment must be installed, configured, and tested according to the manufacturer’s documentation and the site’s approved safety procedures.
