I need a rugged plc

[oldgascar]

I need a plc with 6 inputs and 4 outputs. I must be able to power up the plc with 120 volts. The inputs will pick up and use the 24 volt internal power supply from the plc and the outputs need to be relay outputs.
The unit I have now is a FX1S Mitsubishi and is rated at 1G Vibration Resistance when direct mounted and .5G when din rail mounted.
The old plc I used was a Mitsu FXOs with a Vibration Resistance of
2 G's when direct mounted and 1G when din rail mounted. The old Mitsu plc worked great but
the FXOS is no longer in production and not readily available as old stock.
I am looking for something with Vibration Resistance Values at or above the FXOS values to use in a machine with some vibration issues.
SOOO does anyone know who manufactures the most rugged small plc with 6 inputs and 4 outputs that might work.

If you still want to use the old FX then check www.plccenter.com.

You many want to look at www.automationdirect.com their products appear to exceed those specs.

MIL STD 810 specs are somewhere around 14-15g's.

Why not try dumping mounting?

Why not try dumping mounting?

I assume you mean dampening, that I would do too, using something like these: http://www.midatlanticrubber.com/prod_2.htm

Dampening??? or else I'm lost...heh

because if its a bad mount I would dump ( throw it away ) also.

You may want to look at these things too.

Sorbothane has a higher damping coefficient that rubber, if that matters to you.

Have a look at the new Modicon Twido extreme
http://www.telemecanique.com/en/_data_sheets/aut_modicontwido/fiche2.htm

Looks fairly rugged and the programming software is free

With so little i/o I'll go for the Telemecanique Zelio or Siemens Logo.
Think the zelio has a 1G din rail mounted vibration spec. and its software is also free. Very easy to use

You may want to ckeck into the controllers made for "mobile" applications. These typically go on construction/mining equipment.

One such company is ifm effector:

I have a customer that uses them on cranes in rail yards and loves them.

However, being mobile, you may have to settle for 24V or 12V DC power.
