What cable fits the molex connector best? i have tried several cables but somehow the shield is always to thick

How current can I draw out pins 56 (bat+) and 29 (bat-) if I am using pins 42(bat+) and 43 (bat-) for the input power. I need to power 2 each IQAN sv120 cameras.

What material is used for the molded rear panel of the MD4-10?  I was asked by a customer and couldn't find anything about it in the catalog.

Good morning, we have had a problem with an XC44 expansion module, when we connect more than 5 solenoid valves to the DOUT-(HS) outputs, during the initialisation process, the module is protected and goes into state: SSP (Safe Shutdown Path) with the blink code: R4:2 1:1:1.

The electrical installation has been checked several times and everything is OK and all the clamp diodes are installed properly.

If we start with the solenoids disconnected and when the initialisation process has passed we connect them, everything works correctly.

We have tried to replace the module and it didn't work either.

We have finally had to add several relays to control the solenoids so that the module starts correctly, but this solution involves a lot of tedious extra work.

Can a 12V relay be driven by the LS DOUT of an MD4 supplied with 24V without protection or diagnostic issues?

I have a system that uses an MD4 and some XC21 expansion modules. I am receiving an error code on the MD4 stating there is a VREF error A on XC21[0].

Currently our system uses the XC21 as digital inputs. We have a system power supply that supplies 24Vdc to a switch and then the digital input goes to the other side of the switch. This system has been running fine for multiple years, but now we have the Vref error. 

Since I am not actually using the Vref + at all, I know it isn't overloading. That seems to be the most common answer, as the XC21 Vrefs can only output 70 mA. Is the error bring prompted because something internally is damaged and needs to be replaced? 

Her is a picture of our wiring. C5 and C7 are the Vref A + signal, which aren't wired. C2, C4, C6, and C8 are all digital inputs from our system, all being 24Vdc. The system 24VDC is also powering the MD4 and XC21 so there isn't a concern about different power sources. 

Any thoughts?

How do I upgrade the firmware for my xc42?

Hello,

This is a small but frustrating nitpick.

The XC4x C1 Prototyping Harness (Parker no. 20085116) comes with wires installed in the C1:4 and C1:20 position.

This is annoying, because in order to use these modules, you need to install the ID Tag. (Parker no. 20085131 for example)

So every time you use this (expensive) part, you need to de-pin these two wires, remove them from the harness, and install the ID Tag.

Ideally there would be no wires present in these slots.

Like the older style XA2 Prototyping Harness (Parker no. 5030030).

Regards,

Trying to actuate a 24Vdc coil for a skinner valve with the MD4. I know the MD4 only has LS digital outputs so I am wondering if we would need to use incorporate a voltage divider? I plan on using a relay for that coil as well.
