Incandescent lamp on XC23

Guillaume Fournier 5 months ago in Expansion modules / XC2 • updated by Gustav Widén (System support) 4 months ago 1

Hello,

I am using a DOUT LS on XC23 to drive a 12V incandescent bulb on an instrument panel.  In steady state, the lamp draws 85 mA.  I am getting an overload on this output when I try to activate the lamp.  I was able to temporarely solve the problem by using a 22 ohms in series with the load.  So I believe the problem is the inrush current of the lamp.  The instruction book of the XC23 clearly states that the LS DOUT "are designed to drive small loads, e.g. lamps and buzzers".  The example even shows a lamp being driven by a LS DOUT.

Can you explain if I'm doing something wrong.  If not, is there any fix available to solve this issue ?

Thanks,

Guillaume

Low side outputs protection diode

Guillaume Fournier 6 months ago in Expansion modules / XC2 • updated by Gustav Widén (System support) 6 months ago 1

Hello,

I need to drive relays on low side outputs on the XC-23 and MD4-5.  Do I need to use relays with included coil protection diodes or if the outputs of these modules are already internally protected ?

Thanks,

Guillaume

Using two(2) or more low side outputs in parallel on XC-23

Guillaume Fournier 6 months ago in Expansion modules / XC2 • updated by Gustav Widén (System support) 6 months ago 1

Hello,

I'm wandering if I could use two(2) or more low side outputs in parallel on the XC-23 to increase the carrying current capacity from 300mA to 600mA (2 outputs) or more.  I have a relay that I need to drive that needs more than 300mA.

Thanks,

Guillaume

Difference between XC21, XC22 and XC23

What are the differences between these modules? There doesn't seem to be any information online or in IQAN Design user manual.

Thanks.
