Description
Core Product Summary
The SAM Electronics EMP2200 is a marine-grade process monitoring and central alarm controller engineered for vessel engine surveillance, safety alarm distribution, and machinery automation. Operating on a nominal 24 VDC power supply, the module collects, evaluates, and manages status inputs across main propulsion engines, auxiliary machinery, and shipboard automation loops.
Designed to meet strict marine environmental and electromagnetic compatibility requirements, the EMP2200 incorporates dual RS485 communication interfaces and CAN bus network connectivity. Its rugged construction provides high resistance to vibration and thermal stress, ensuring continuous monitoring and relay control output across commercial shipping, offshore platforms, and marine automation architectures.

Detailed Product Overview
The SAM Electronics EMP2200 serves as a core processing and operator interface unit within engine manoeuvring, alarm monitoring, and shipboard safety control networks. Situated within engine control rooms (ECR) or main bridge consoles, the unit continuously scans binary and analog field signals representing critical operating parameters such as oil pressure, cooling temperature, engine speed, and fault interlocks.
To maintain system integrity on vessel electrical grids, the EMP2200 operates over a wide 18 to 32 VDC tolerance band, protecting internal logic against voltage fluctuations and transients. System integration relies on dual RS485 channels and CAN bus protocols to relay real-time process values, trip signals, and event logs to central ship management systems or remote operator display panels.
Installation requires proper attention to marine grounding standards, signal cable shielding, and bus termination setting. Address DIP switches and jumper configurations on the main board allow engineers to configure network node addresses and line termination resistance according to the vessel’s specific wiring topology.

Dimensions, Mounting & Connection Notes
- Power Input: Connects to a nominal 24 VDC supply via dedicated terminals on the rear 24-way block (X1).
- Communication Cabling: RS485 network channels utilize dedicated wiring blocks with selectable termination jumpers (ON/OFF) to prevent signal reflections over long cable runs.
- Circuit Protection: Fused internally at key terminal points, including power supply input protection and relay loop fuses.
- Grounding Requirements: The unit chassis must be bonded to the vessel’s main protective earth bus with heavy-gauge copper grounding wire to meet marine EMC standards.
- Environmental Precautions: Install in a climate-controlled console or IP-rated cabinet protected against direct moisture ingress, salt spray, and excessive heat.
