ECP-4200 Interface Unit (EIU)
The EIU directly interfaces with the ECP 230 VDC Trainline power supply and is connected to the NIU-II. It also acts as a gateway between the NIU-II and Trainline Network to allow HEU/LCM messages to be passed between the Trainline network devices and the NIU-II.
- Interfaces directly to the Trainline Power Supply and NIU-II
- Discrete 74 VDC I/O
- PCS Relay (NO & NC operation)
- Power Supply Controller Logic
- ECP Trainline Interface for NIU-II
NOTE: The previous Locomotive ID (LID) functionality is now integrated into the cable between the EIU and NIU-II. This cable has an integrated static memory for maintaining the Locomotive Static parameters specific to each customer application.
230VDC Trainline Power Supply
Converts locomotive battery voltage to the 230VDC power required to operate ECP equipment
Network Interface Unit (NIU-II)
Provides the interface for communications with industry standard locomotive systems
Installed on the front and back of each ECP locomotive to provide connections with adjacent locomotives or cars
