Replacement Analogue control cards

The ZX393 Sequence Controller Board is fully versatile for input voltage, output voltage, number of ways, pulse length and time between pulses. You select the number of ways by ordering 2, 4 or 6 way units. Each unit has an on-board selector to pulse any number of ways you like up to the nominal. In other words a 2 way unit can pulse 2 ways; a 4 way unit does 1, 2, 3 or 4 ways and a 6 way unit covers all the options up to 6ways.
