EU-Detector Cable — Minecraft block

EU-Detector Cable

EU-Detector Cable outputs a redstone signal while EU energy flows through an IndustrialCraft 2 power network.

Description

EU-Detector Cable is an IndustrialCraft 2 cable that emits a redstone signal whenever EU energy flows through it, so you can automate machines based on power transfer. It is crafted from one HV Cable, one Electronic Circuit and three Redstone, and it carries high-voltage current just like the cable it is built from. Place the EU-Detector Cable anywhere inside an IC2 energy network — for example between a generator and a machine — and it outputs a redstone signal the moment current passes and none while the line is idle. Players use it to switch on lamps, trigger pistons, or start a backup generator automatically when a battery bank begins drawing power. The block belongs to IC2 Experimental and pairs naturally with the EU-Splitter Cable, which works the opposite way: a redstone signal applied to the EU-Splitter Cable stops the EU flow through it. The EU-Detector Cable transfers EU packets of up to 512 EU and loses 0.5 EU per block; covered in Construction Foam, it can no longer output its redstone signal.

IndustrialCraft 2 Guide

How to use the EU-Detector Cable in Minecraft

  1. 1

    Craft the cable

    Combine one HV Cable, one Electronic Circuit and three Redstone in a crafting table to make one EU-Detector Cable.

  2. 2

    Insert it into the network

    Replace a section of cable between an EU source and a machine so all current must pass through the detector.

  3. 3

    Wire the redstone output

    Run redstone dust from the cable to the device you want to control, such as a lamp, piston or another generator.

  4. 4

    Test the energy flow

    Power the network: the cable outputs a redstone signal while EU moves and none when the line is idle.

Important

EU-Detector Cable is an IC2 Experimental block; in older IC2 Classic builds the recipe and transfer tier can differ.

Frequently asked questions

What does the EU-Detector Cable do?

It emits a redstone signal whenever EU energy passes through it, letting you automate machines based on power flow.

How do you craft an EU-Detector Cable?

Place one HV Cable, one Electronic Circuit and three Redstone in the crafting grid to make one cable.

What is the difference between the Detector and Splitter Cable?

The Detector Cable emits redstone while energy flows; the EU-Splitter Cable is the opposite device — a redstone signal applied to it stops the EU flow.

Does the EU-Detector Cable lose energy?

It transfers EU packets of up to 512 EU and loses 0.5 EU per block along the way.

Does the redstone signal pass through Construction Foam?

No — covered in Construction Foam, the EU-Detector Cable cannot output its redstone signal.
