When Can I expect an XC4 family of modules?

Forrest 3 years ago in Expansion modules updated by Johan Lidén (Product manager) 2 years ago 11

The MC41/42/43 looks like a great series of products, but I am reluctant to go with a 3 or 4 master system. When can we expect a series of expansion modules along the lines of the MC41/42/43? or am I stuck with the XA2 indefinately for current outputs?

Directional Motor Control with COUTs

Luke@ARI 2 years ago in Expansion modules / XA2, XS2 updated by DavidH 2 years ago 5

Hi all,

I'm thinking about controlling a motorized hydraulic pressure relief valve (the motor turns the pressure setting in and out) with two COUTs on an XA2 module. The motor was previously controlled with a couple of digital outputs and relays as an H-bridge. This is more of a XA2 hardware question; are the diodes necessary to protect the high side COUT as shown?:

Obviously only running either COUT A or COUT B at a time.

Or are diodes not needed?:

Thanks,

Luke.

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

Externally Mounted Module, Diodes?

Lars Bolduc 1 year ago in Expansion modules updated by DavidH 1 year ago 2

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.

Incandescent lamp on XC23

Guillaume Fournier 2 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 2 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

VREF error on XC43 Enable

jolynik 4 months ago in Expansion modules / XC4x updated 2 months ago 10

Working on a project in which 2 XC43 modules are not supplied with power until the MD4 commands a safety relay contactor closed.

I've worked through almost all the bugs, but I'm getting a VREF A error as soon as the XC43 modules enable. I've tried leaving up to a 30 second delay after powering the XC43 modules to enable them, but the error still pops up for one cycle and then shows up on screen (Watching in a measure group, VREF starts at 0V for one or so cycles, then goes right to 5V). All the sensors read fine, just have the error at system start.


Is there any way to delay how long it takes for the VREF error to show

W out engine alternator connect to frequency in terminal C1:24 XA2

claudio 9 months ago in Expansion modules / XA2, XS2 updated by Gustav Widén (System support) 9 months ago 1

Hi to all

Is it possible to connect the terminal W of the engine alternator to terminal C1:24 "Frequency In" of the XA2?

The diesel engine work at 24V , it is an old engine and don't has the J1939 bus.

XC10 POWER CONTROL input consumption

Adolfo 10 months ago in Expansion modules / XC10 updated by Gustav Widén (System support) 10 months ago 3

Can I know the XC10 POWER CONTROL input consumption or input resistance?

I cannot find this data in the iqan-xc10_uk_instructionbook 2016...

Thanks in advance and best regards.

xc43 referance voltage

Ed Schippers 10 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 2 months ago 3

On the XC4x serie there are multiple Vref+ and Vref- and on both C1 and C2 

Are these interaly connected in the module? 

Or are they seperate from eachother and serve only dedicated Vin's?

Best Regards Ed

PWM OUT HS to control proportional valve "D1FBE01HC0NJJ3"

Hassan 11 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 10 months ago 2

I'm using the expansion module XC43 to control valves, usually, I use Cout to control proportional valves but I run out of current output pins " I have 13 valves" I'm wondering if I can use PWM OUT HS to control D1FBE01HC0NJJ3 " Proportional directional valves in general " also L90LS, P70? Because it seems for me that PWM is only to control pulsar valves that have some frequency working value.
