MC41 Molex connector Out of stock
Has anyone been able to find out where to get a supply of the new Molex 216741-0001 (new connector) The UK seems to have no stock at all and we are getting desperate now.
Molex MX series
I understand that there was a change from Molex regarding the MX series connector for the MC43. 34822-0013 changed to 216741-0001. The issue is, there is no stock in the US distribution. Are there any other connectors we might be able to use as an alternative until US inventory has stock within the distribution channels?
UL/CSA Listing
The datasheets do not claim any UL or CSA compliance.
I see other brands of PLCs do.
Having a UL508A control panel is a nice feature.
Any thoughts?
module identification
Marking MC/XC modules
is it possible to mark the modules with the type on the connector side.
if the module is mounted its not possible to see wich one it is
MC4x Evaluation board
An MC4x evaluation board is now available to order, part number 20085169.
This board is meant to be used with all the MC4x units and will connect to C1.
It has all the I/O for C1 connector and can be used for testing everything on MC41 and MC42 and all I/O for C1 on MC43.
The kit includes the board and test cables.
IQAN-MD5 - release of 5" and 8"
We have now released the first two variants in the IQAN-MD5 family, the 5" and the 8" variants.
You'll need IQANdesign 7.02 to use these, which also is available.
Product information are available on parker.com.
The IQAN-MD4 platform will continue to be supported alongside the newly introduced IQAN-MD5 platform. Our standard End-Of-Life (EOL) process for products involves a notification given three years prior to the Last Time Buy (LTB) opportunity, followed by a period that allows for last-time purchases, with the last delivery occurring approximately two years after the LTB date.
In the long term the IQAN-MD5 platform will live longer and is a better choice for you when planning your platform moving forward.
MD4 day/night mode.
Would be nice for MD4 displays to have day/night mode where background and text properties would change without the need of creating extra layers.
XC43 Functional Safety
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?
Coil Suppression on MC4x Outputs
Hardware Question:
In the Documentation for the MC4x family of controllers - it says in many places to use diodes for external coil suppression, for example when driving a relay with the Digital Out HS driver from the MC4x.
A relay that I have specific to my application requires (highly recommends) the use of varistor coil suppression, which is less "harsh" on the relay device during transients. The specification requests a clamping voltage of 3x the coil voltage, i.e. 36Vdc for a 12Vdc relay coil.
Are there any adverse affects of using a varistor instead of a diode for coil suppression?
Perhaps this could be also compatible with the hardware design of the MC4x series of controllers?
(Hint: I already have tested this configuration on my system to many thousands of cycles under load with no discernible affect on system operation or relay operation)
