A Guide to Cabling Sensors and Modules to an eDart

A Guide to Cabling Sensors and Modules to an eDart

An RJG eDart is a robust system that can help a molder monitor and manage the injection process in order to consistently make good parts.Much of the focus is on the eDart, the software (v9 or v10), the modules and especially the sensors.Questions have been asked in regards to cabling these devices to an eDart and this guide may help.

There are 2 ports on the back of and eDart (see below) that can send and receive signals, hence these ports are bidirectional.Pressure sensors, temperature sensors, sequence input modules are a few devices that give an eDart signals.An relay output module can take a signal from an eDart to implement external controls, i.e. V to P transfer or conveyor belt control (containment).

30 each port



The 2 ports on the eDart can, each, handle up to 30 sensors or modules for a maximum of 60.The number on each port may be more or less, depending on the application.
This is due to the limited amount of power being placed on the cable through the port.It is important to stay within this number to ensure that sensors or modules are not “dropped” from being seen by the eDart
.

CABLES

Cables are the links that carry signals to and from the eDart.Each end of the cable has a connector.One end is female and the other end is male.

CE-LX5-F90


The female end has two options either straight or at a 90 degree turn.This can help when placing sensors in an area that has minimal room.

Cable Model and Length


Cables can directly connect into one another if you need to extend its length.



Sensors and Modules


Sensors and modules all have male connectors.



The female end of the cable (either straight or F90) will connect in to these devices.




Junction Boxes

Junction boxes allow for multiple devices to be added to single eDart port line.



There are 4 different models of junction boxes.



Junction boxes can be “daisy chained” to allow for even more sensors on a single eDart port for a maximum of 30 devices per port.



eDart and Lynx Network Layout





There are limitless ways to cable an eDart/Lynx network.The following are tips that will help:
· When running wires along the mold and machine, make sure cables will not be near a pinch point.
· Avoid running cables near motors and servos, along power conduits or load cells.
· Secure cables well without crimping the cable itself.
· Allow for enough slack (without crushing) of the cable if there is a need for range of motion.
· It is recommended that you do not exceed 20 meters total cable length between a sensor/module and the eDart.
