Digital Relay Output Module
The EKE-Trainnet® Digital Relay Output Module (DRO) provides standard relay contacts.
It receives commands from the train computer’s Central Processing Unit (CPU) module and controls the output relays accordingly.
The EKE-Trainnet® DRO module can be used as a part of an EKE-Trainnet® Train Control and Management System, Vehicle Control Unit or Event Recorder. Alternatively, the EKE-Trainnet® DRO can be fitted into the EKE-Trainnet® Remote Input Output System.
Key Features
The DRO modules are able to take up pre-set output states in case of an emergency. If the communication between the train computer’s CPU module and the DRO fails, the relays go in to emergency states that you can define in the application software. When the EKE-Trainnet® DRO is unpowered, all relays are in the Normally Closed state. Emergency states should be defined to match the wiring to Normally Open (NO)/ Normally Closed (NC) contacts.
Options
The EKE-Trainnet® DRO2342 features 8 Single Pole Double Throw (SPDT) relay output channels on the front panel, while the DRO5141 version has 4 SPDT relay output channels. Relay contacts are accessible via the DIN41612 connector on the module’s front.
