Force Feedback Questions

[preetsei]

Hi,

I'm relatively new to the virtual pinball hobby and working on my first cabinet build. I'm using a Led-Wiz and have a couple of questions regarding some force feedback components:

1. I recently acquired a couple of Allen-Bradley 24V contactors that I plan on using for flipper feedback. The coils on these are rated at 916ma peak and 416ma average. Question is, how does this compare to the ratings of the Siemens contactors that most folks here seem to use, and do I need to put a relay (or a transistor based circuit) between this contactor and the LedWiz?

2. I'm looking for some solenoids to use for pop-bumpers and slings. Has anyone used these: http://cgi.ebay.com/ws/eBayISAPI.dll...m=250942434525 , and if so, do they work well, and do they require a relay between them and the LedWiz?

Thanks!

better use a fast switching opto/driverboard with these Allen-Bradley contactors (like the ledwiz booster board from zebulon)... otherwise you will fry your ledwiz with these bad boys

siemens contactors can be directly connected to a ledwiz, because the mA is under 350ma.

check also the speed and the sound of these contactors/coils first. Not all sound and react like the real deal.

Thanks for the quick response Chris! Would something like this work for driving/isolating these: http://www.ebay.com/itm/4-Relay-Modu...item3a72c800c5

better go with fast optorelays or opto/mosfet driverboards, because normal relays (like the quad relay board you posted) are too slow for fast swichting contactors.

Thanks for the tip!
