Is there engineering drawings online for the DEC 871 or 874 power controllers?
I have one with a failed solid state relay and I cannot figure out the spec. One is an Opto-Film OFA-2402H and the other is a CLARE 203A05A3A But I cannot find a data sheet for any of those. Does anyone know a compatible replacement device? The pinout is not something I can find amongst the ones at Mouser. /Mattis
