When Can I expect an XC4 family of modules?

Forrest 2 years ago in Expansion modules updated by Johan Lidén (Product manager) 1 year 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 1 year 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?:




Externally Mounted Module, Diodes?

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


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


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 ?




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

claudio 6 months ago in Expansion modules / XA2, XS2 updated by Gustav Widén (System support) 6 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 6 months ago in Expansion modules / XC10 updated by Gustav Widén (System support) 6 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 7 months ago in Expansion modules / XC4x updated by Kerry 7 months ago 1

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 7 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 7 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.  


External Mounted Modules

BLC 9 months ago in Expansion modules updated by DavidH 9 months ago 1

I'm being asked to mount modules external to the main enclosure, XC41's to be exact. So there will be an enclosure to mount the MD4 to but everything else will be mounting on the rock crushing machine. The power and ground for the modules will come from within the main panel and be fuse protected. The issue I'm having is trying to solve the ground and power that is supplied to the DIN's and DOUT's. Is there a way to cleanly create a ground line and power line to run along the machine and tie into for each necessary I/O? I was thinking of a isolated buss bar, or perhaps a two to one butt splice. Any ideas will help.


Expansion Module CANBus

Greg R 11 months ago in Expansion modules / XC4x 0

Our usual setup is an MD4 with an XC4X expansion module. But we end up using an MC4X because we need the CANBus available on the master module. It would be nice if the expansion module provided access to additional CANBus the same way it provides access to its IO.
