XC21 Digital out LS

Stefan Hedlund 1 year ago in Expansion modules / XC2x updated by Gustav Widén (System support) 12 months ago 1

XC21. Is it possible to connect 2 Digital out LS in parallel to drive more load?

I want to connect a buzzer that draws about: 400mA

Incandescent lamp on XC23

Guillaume Fournier 3 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 3 years 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

DOUT error code flash on XC23 when output is disabled in IQANdesign

Kevin Arscott 5 months ago in Expansion modules / XC2x updated by Gustav Widén (System support) 4 months ago 1

We have an application which has an optional function group containing a DOUT on an XC23 module. This function group is enabled or disabled using a digital parameter. With the function group disabled we get the output grey and 'disabled' state when measuring with IQAN Design, which is correct:

We also have no errors on screen stating open load (we have nothing connected to output because this machine has not got the optional extra fitted). XC23 module has error code flash of DOUT, I suspect open load. Its not logging any errors or open loads in any logs within master module, viewing state of the module using IQAN Run I also get 'OK' and no errors on status screen just the LED status is showing incorrect state directly on the module:

If I delete the output from IQAN Design the error flash on the module disappears and it goes a steady amber flash, no errors.

Has this been fixed in a newer version? IQAN Design 5.06, MD4-5 M19 and XC23.

XC-23 minimum input voltage

Guillaume Fournier 3 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 3 years ago 1

Hello,

I have an H-Bridge that drives a DC brushed motor on 12V. I need to determine the PWM ratio being supplied to this motor by the H-Bridge. There is no other signal that could get me this information so I am contemplating hooking both sides of this motor to PWM inputs on the XC-23. Before doing such a thing, I looked at the signal using an oscilloscope. Basically, the signal is 0-12V most of the time but dips below 0V when the ON time finishes. The lowest voltage read with the scope is -11V for a short period of time.

There are no Absolute Requirements for negative voltages on inputs in the datasheet of the XC-23. What is the absolute minimum voltage that can be applied to a PWM input of the XC-23 without damaging it ?

Low side outputs protection diode

Guillaume Fournier 3 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 3 years 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 3 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 3 years 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

20mV jumps on VIN from XC23

Kevin Arscott 5 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 9 months ago 2

We have an application for some voltage signals to be connected to the MC3 application. We have selected an XC23 module which compares a VIN signal on the MC3 with a VIN on the XC23. We have two of these functions (1 x MC3 VIN and 1 x XC23 VIN = one of two comparison functions in the application) measuring two different positions using sensors.


We have found that one set (an MC3 and XC23 VIN comparison) seem to follow almost exactly, however the other pair, the XC23 signal appears to increase and decrease in approx. 20mV steps. We are using VIN E and F on the XC23 and it appears the VIN F is causing the stepped signal even though it looks like it should have an accuracy of 1.22mV.


We have changed the sensor and XC23 module, but still appears to be doing it. Is there any reason for this behaviour? I have checked the VREF in the application, and all the VINs are configured to the correct reference voltage.

Difference between XC21, XC22 and XC23

Kevin Arscott 7 years ago in Expansion modules / XC2x updated 7 years ago 3
What are the differences between these modules? There doesn't seem to be any information online or in IQAN Design user manual.

Thanks.
