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

Hello,

We are going to be mounting an XC43 externally. The module and connector are rated for it, IP6K9K.

Has anyone else done this?

How does one go about neatly mounting external diodes for the digital outputs?

I need diodes that go between HS DOUTs to ground and between the pins of HS+LS DOUTS.

Regards,

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

Hi,

Our transmission manufacturer uses a 2-pin magnetoresistive (MR) speed sensor.  The output is 7 mA for low signal and 14 mA for high signal.

The frequency range would be 0-1500 Hz.

Given that FIN is looking for <1V low and >4V high on an XC43, we can't condition the signal with a simple current-sense resistor.

Do you have any suggestions on how to integrate this type of sensor into a XC43 module?

Recently we encountering "No Contact Error" in our system,  but we found out that the cause of the problem is when the XA2 unit temperature goes to 42-46 degree it creates no contact error, but my question is, why it is happening if the operating temperature of the XA2 is up to 70 degree Celsius. I check on Diagnostic, Voltage are okay, Status okay, Address okay, only that the temperature is high.

We've used the 24V DC relay (datasheet is attached) on a XC43 High Side DOUT, but it doesn't seem to like the relay and show us a Open Load error. Could you please help us understand why this happened? Is there anything we need to pay attention to when using relay?Section-1_35_2018.pdf

Good afternoon,

I have a system that uses an MD4-5 as the master and several XCx modules as extension módules. One of the XC44 modules randomly fails to connect when I power up the system, and the LEDs indicate the following error:

"R4:3 3:1:7 Startup check. Expected after update of XC4x to FS capable version."

This error is random; it may not appear for a week or it may appear several times on the same day.

I have checked the wiring and it is correct, as is the battery voltage.

We are having a problem with XC43 giving overload errors in multiple DOUT's at the same time.

Construction of the application is MD4 + 2xMC43 + 3xXC43, running with IQANdesign 6.08.

Problem is only in one of those XC43's. We use those DOUT's to control two different kind of solenoids, connected as shown below:

Fault codes are occurring only in:

• C2:29 (load 0,83 A), C2:13 (0,83 A), C2:30 (1,29 A) and C2:14 (1,29 A) overload simultaneously
  • If you activate only one of these DOUT LS's, every one of those are giving fault code
• C1:58 (1,29 A) and C1:42 (1,29 A) overload simultaneously
  • If you activate only one of these DOUT LS's, both of those are giving fault code
• C1:60 (1,29 A) and C1:44 (1,29 A) overload simultaneously
  • If you activate only one of these DOUT LS's, both of those are giving fault code

Sometimes you can drive a day without having any fault codes, sometimes fault codes appear at the first activation at the morning. Even when the machine is standing still, only ignition on and you are activating those solenoids, it can be that you can activate those 50 times without problem and then suddenly the next activation gives you the fault codes.

We have replaced that XC43 with the other one installed in the same machine, still giving the fault codes. The original XC43 didn't give any fault codes when installed to another location. We have checked and measured all the wires, not shorted to the ground or to each others. Measured the coils, everyone has the correct resistance. Replaced all the diodes at the solenoids' connectors, no change. We have dozens of machines with exactly same construction and none of those are having the similar problem.

Any ideas how we should proceed with the troubleshooting? Thanks!

We are providing some sensors with a 0V supply through the VREF circuit on XC43 module but cannot find the maximum current capacity of these pins. The manual states VREF has a limit of 150mA, but is this limitation on both the +ve side and -ve side?

I was under the impression -VREF is connected internally to the -BATT terminals, therefore does this mean there is a higher current limit? I cant find a value in the manual:

we have strange behavior which XC43 Has constant high output as soon as get powered on , 

we have replaced 3 modules but the same situation was income .

temporarily that output sealed and waiting for your advise .
