Description
The ABB CMA137 3DDE300417 is an additional functions connection module and terminal interface board engineered for the ABB SYNPOL-D generator control and power management platform. Installed inside marine switchboards and generator control cubicles, the module provides structured field wiring termination to route external signals to the central control hardware.
Interfacing directly with the SYNPOL-D basic controller rack via designated system bus Cable E, the CMA137 module serves as the physical hardware termination point for auxiliary function output relays (channels 11 through 18). Additionally, it provides input termination for specialized generator operations, including auxiliary 5 to 10 VDC load reduction control inputs used during shaft generator integration.
Features
- Dedicated terminal interface board designed specifically for ABB SYNPOL-D systems.
- Direct ribbon cable interface to the central SYNPOL-D rack via Cable E.
- Field wiring termination for programmable function output relays 11 through 18.
- Dedicated terminals for 5 to 10 VDC analog control inputs for shaft generator power limits.
- Heavy-duty screw-clamp terminal blocks for vibration-resistant field connections.
- Compact horizontal mounting profile tailored for main switchboard (MSB) installations.
Applications
- Marine main switchboard (MSB) diesel generator control panels.
- ABB SYNPOL-D marine power management systems (PMS).
- Shaft generator operational control and dynamic load-shedding systems.
- Auxiliary generator fault tripping, status monitoring, and function relay expansion.
