coupled to isolate the iDR-switchfrom the connected equipment. It provides an open collector output with floating collector (+pin) and emitter (-pin).

Each 10way connector provides 4 open collector pairs as well as an internal +10V DC supply and ground pins. Do not use the chassis ground screw which is for cable shielding and safety grounding only.

The output may be used in many ways to satisfy a wide range of interfacing applications. It is important that the installer has a good working knowledge of open collector and interfacing circuits. Incorrect application may result in damage to these outputs.

The internal +10V supply may be used as the power source for low current applications such as turning on LEDs, lamps and small relays. One cable can feed the common supply or ground to a bank of outputs.

Maximum current drawn from the +10V supply for all outputs combined must not exceed 500mA. Care must be taken in component choice to ensure each operates within its specified capability.

For higher current or voltage applications an external DC power supply may be used. This also provides total isolation between the iDR-switchand external equipment.

Maximum external supply voltage must not exceed +24V DC. Maximum current sink through any open collector output must not exceed 200mA.

A few examples are shown in the diagram here. For further advice contact Allen & Heath technical support.

Remote controllers The iDR-switchis designed to be

used with a wide range of remote control devices including custom wall plates and operator panels. Check out the Allen & Heath range of PL wall plates and remote controllers. This range is continually developing and it is likely that some may be suitable for your application.

At the time of print of this user guide the PL-2wall plate is available for use with the iDR-switch. It has 4 switches and 4 3-colour LEDs which can be hard wired to the unit. It can be fitted into a UK or US standard single wall box. For further details visit the Allen & Heath web site.
