ASi connection aids signal tower integration

A Lenze product story
Edited by the Engineeringtalk editorial team Sep 26, 2003

A new range of signal towers with three colours can be connected directly to ASi fieldbus cables.

A new range of signal towers with three colours can be connected directly to ASi fieldbus cables.

They can even be combined with other devices on the same cable, saving costs in machine wiring and installation time.

This makes use of the low cost ASi fieldbus even more attractive by integrating safety and status indicating lights.

This new range of Patlite signal towers has 50 or 70mm diameter bodies and LED lamps, which achieve a lifetime greater than 100kh.

There is also a wall-mounted indicator, which has a depth of only 37.5mm.

All models are available with three colours - red, amber and green - and with an optional 90dB audible alarm.

As current consumption is low - typically 50mA or less - the signal towers can be operated off a single ASi cable provided the total demand for the system is less than 2A.

This means that the single ASi cable is providing the 24V power supply and handling the signalling.

For larger scale networks, there are also signal tower models suitable that use a second ASi line for 24V auxiliary power supply.

Incorporating ASi technology into signal towers simplifies electrical design for machine builders and saves on costs.

Patlite signal towers are available in the UK from Lenze.

Also available are signal towers and wall-mounted indicators for DeviceNet connection.
