Durable, indoor tray that can host a DC-DC converter, Elara, and extensions with terminal blocks connection for easy wiring and quicker installation time.

The Cabinet Tray is designed to be installed in a standard cabinet (19’’ width and 2U height).

Cabinet Tray Layout

In telecom sites we have many sensors and panels, therefore, we created this efficient tray, to help manage all the wires, and to be on top of things.

Main Input Fuse

This is the main fuse and input of electricity for the tray, it can receive from +18VDC to +75VDC, the main fuse need to be connected to the DC to DC power converter.

DC to DC converter

The converter converts the input voltage (18VDC-75VDC) to +12V, since most of the sensors and devices, including ELARA, are working on +12VDC.

Grounding

Grounding is made to protect the sensitive electrical equipment in the tray, the grounding resistance should not be more than 5Ω.

Wiring Ducts

Wiring ducts are made for cable organization, all the cables from the sensors & devices on the site are designed to go through these wiring ducts.

GND & +12V Terminal

Extension terminal for GND and +12V power.
These are the main power slots for all the consumers in the tray, it is receiving power from the DC to DC converter.
Any device in the tray should consume power only from the terminal blocks.

RS485 Terminal

Extension terminal for the ELARA’s RS485 port, to provide a serial connection between the ELARA and the other devices and sensors on the site.
The orange terminal is for Port A and the blue wires are for Port B

ELARA Slot

The ELARA slot is a place for the ELARA on the din rail, with the exact length of the green connectors, dedicated for the ELARA.

EX20-1/2 Slot

The EX20-1/2 (Extension Devices) slot is a place for the EX20 on the din rail, with the exact length of the green connectors, dedicated for the EX20.

Elara & EX20-1/2 Terminal

All the inputs & outputs of the ELARA & EX20 are extended to the gray terminal, to have organized & comfortable connections to the devices.
Each input in the gray terminal directly extends the actual input in the ELARA or EX20.

Hatch Sensor

The Hatch Sensor exists to indicate if the tray is opened.
As a convention, it always will be connected to the 5th input of the ELARA.
