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 I/O System.
Key Features
The DRO modules are able to take up pre-set output states in case of emergency. If the communication between the train computer’s CPU module and the DRO fails, the relays go to emergency states that you can define in the application software. When the EKE-Trainnet® DRO is unpowered, all relays are in Normally Closed state. Emergency states should be defined to match the wiring to Normally Open (NO)/ Normally Closed (NC) contacts.
Options
The EKE-Trainnet® AIM2505A has 10 current channels and 10 voltage channels divided in three isolated groups. 4 frequency channels are also available.
The EKE-Trainnet® AIM5250A has 6 current channels, and 6 voltage channels, and 4 frequency input channels in two groups: two for the low-voltage tachometer measurements and two for the high-voltage pulse width modulation measurements.
