When Can I expect an XC4 family of modules?

Forrest 4 years ago in Expansion modules updated by Johan Lidén (Product manager) 3 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?

XC43 Functional Safety

Michael Carlyle 9 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 6 months ago 6

Will the XC43 (when paired with the MC43FS) inputs to be allowed for use in Functional Safety Marked Function Groups in a future version of IqanDesign?

Directional Motor Control with COUTs

Luke@ARI 4 years ago in Expansion modules / XA2, XS2 updated by DavidH 3 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.

XC44 HS+LS Overcurrent

CalebD 6 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 3 months ago 9

We are experiencing a problem with the HS+LS outputs on an XC44 module connected to an MC43 as the master running IQAN 6.07. Pin C1:46 as the HS and pin C1:41 as the LS.

The outputs are being used to activate a solenoid. The circuit was wired to run through a relay latched by system estop, with a diode placed across the solenoid to protect the outputs as in the documentation.

This circuit is able to latch and unlatch the solenoid with no problems, and this was repeatable many times. However when the system estop is pressed for the first time and the relay unlatches and breaks the circuit there is no error. When the relay is energized and the circuit is connected again, when the output is turned on a message is displayed reporting that the LS pin is overloaded. This message then triggers on either side of the estop from that point on. Key cycle is able to "reset" to the first estop cycle. This behavior happened ~9/10 times the cycle was repeated. There were some occasions where the error did not trigger.


The overcurrent error will only trigger when the output is requested, the estop relay can be re-energized connecting the circuit and no overcurrent is reported. 

Current measurements were taken on the HS+LS wire to investigate. The current on this wire never approaches or exceeds the listed 2.5A. This is the only load on that pin grouping, the other 3 LS pins were not used.

XC42 DOUT HS working with high impedance inputs

Adolfo 1 year ago in Expansion modules updated by Gustav Widén (System support) 1 year ago 1

Hello,

We are designing our last machines with XC42 instead the phase-out XC10 and we are experiencing some issues.

One of them is related with the activation of some Inverter (Euradrives) and Soft Starters (ABB) digital inputs.

When the DOUT HS is directly connected to those high impedance inputs and the output is OFF, surely due to the leakage current, the Inverter and the Soft Starter interpret it as ON state, so they run untimely!

It is possible to reproduce this just wiring a DOUT HS to a DIN PD, the input will be ON all the time, even when the DOUT is OFF:

Also, when the inpedance is very high (not with XC42 DIN PD in this case), the DOUT HS is ON, the Open load error appears due to low consumption of the high impedance inputs, and this checking cannot be disabled in the IQAN...

We thought to add and extra resistor in parallel to the high impedance input to avoid this error, but we don't like this "solution", it can be really dangerous because if the resistor is broken or loosen, the devices will be running untimely!!

Our only solution was to add 24Vdc relays in the HS outputs and wire the contact of the relay to the high impedance inputs.

We think that the best solution would be the possibility of disabbling this leakage current for Open load ckeching in the DOUT HS. Is there any possibility of implanting it in future releases?


Thanks for your help and best regards,

Adolfo

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 3 years ago in Expansion modules updated by DavidH 3 years 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 4 years ago in Expansion modules / XC2x updated by Gustav Widén (System support) 4 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

Vin reading errors on XA2

Forrest 2 months ago in Expansion modules / XA2, XS2 updated by Gustav Widén (System support) 2 months ago 1

I was forced to change my Pressure Transmitter due to the world-wide supply chain mess.

One that I could get my hands on that looks like it should be able to do the task is the IFM PU1700. I get wild reading from it when read by the XA2, but when I read it with a multi-meter, the voltages are right were I would expect them to be.

Any ideas of what to do? Is there a way to determine what will work and what wont without buying, waiting, and trying?

XC-43 Modules Leakage Current/Voltage

Jamy 2 months ago in Expansion modules / XC4x updated by Gustav Widén (System support) 2 months ago 1

The Leakage Current/Voltage from the Digital Outs make it difficult to control LED's and Audible Devices without using a relay/resistor/other.  The Leakage Current/Voltage is also making it difficult if the Digital Outs are read by other electronic devices (off is not off).  How does Parker recommend interfacing with these devices using the new XC-43/series modules? Adding external devices to these circuits is making the XC-43 modules not very convenient.
