Hi, I'm looking to purchase a second-hand MD4 (and XC42) to replace our current control system. Has anyone got these in stock that could be shipped fairly quickly?

Thanks in advance!

I am testing logic with a MC43 and using a PWM HS+LS output.

In the system we are using both sides of the output (+ and -) to drive two individual devices.

Both should never operate at the same time.

To simulate one of the device not operating, we unplug one of the solenoids.

With logic, this automatically causes the other side of the output to now function.

Basically, if the + side fails, it should switch to the - side and operate.

We are getting an open load error on the output with one of the solenoids unplugged and it does not allow us to operate the other solenoid on the PWM HS+LS output.

Is the output designed to shut off both sides if one side detects open load or should the other side work if one side detects open load?

As an example:

If the solenoid between C2:67 and C2:15 is unplugged, but the solenoid between C2:67 and C2:31 is plugged in and fully operational, should we be able to command it with an input signal of -100?

Is the MC4X PWM Input able to monitor frequency ranges outside of it's normal function like 1000 Hz and if so what would the effects be with the resolution of the readings from the MC4X? 

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.

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

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. 

We have installed a brand new display in a battery powered rig this week. Its serial number starting with 2305 and production date of 230202.

It has been OK for a week but after the battery in the rig went flat, this line appeared:

Only thing I can think of was the battery was depleted and resulted in the display flashing when the battery got to a level where it was unable to power the module. It performed OK after the battery was recharged but after a few hours the line appeared. 

Anyone had this problem or similar before?
