1 x UB-1 arrived 3 days via fedex (Thailand > UK).
first impressions are a very neat and well made board.
I am not posting any specific parameters as the manual will no doubt provide switching current limitations etc.
no doubt I'll have a few questions I hope the manual will answer (such as option setting 12 "board ID -> 5LPT/UB1"?)
the 3 onboard relays seem quite fast switching time (sub 1msec operate & release)

http://www.farnell.com/datasheets/1646144.pdfI await a suiable daughterboard (neatest option seems to be the CNC4PC C10
S which is 26PIN IDE <> IDE plugin compatable..... unfortunatly only 5V rated from what I can see.
Note: they do an non "S" variant although this will require a LPT connector, IE not as compact and has screw terminals where as the "S" has the IDE connector or LPT and push in terminals (same as the UB1)
