[GreenKeys] Current Loop Gadget

[Jack Hart]

ZCZC

 

Those of you who surf Ebay might have come across

a company call "centralsurplus" selling 

"Kenway" RS232/current loop stuff.

 

They have had a small circuit board loop adaptor

listed for $150 for a long time. I offered $20 once

and was turned down flat. Well...I just got the board for

99 cents on their "or best offer" listing!  HA!

 

The board looks new and it will be easy to trace

the circuit and parts(!). Probably not as "modern"

as the circuits we have seen on Greenkeys, but

interesting...especially for 99 cents!
