?Without the speed up, they will operate in 2-3 msecs.? The 3PDT clunker u have in there now will be 18-20 msecs at least.?
You could even leave the oem FWCT? 12 vdc supply in there.? ? Just toss the oem? clunker....and replace it with? 3 x vac relays, each with a 12 vdc coil...and wire all 3 x coils in parallel.? ? Then no drop resistor required.? ?Each coil will draw 1.8 watts? (5.4 watts in total)? ?on TX...and zero watts on RX.?
You will have to get creative on locating them,? but it's doable.? ? I still have the 2K-3 PDF manual saved.? ?I didn't realize this was an antique.?
?
The actual pickup / drop out voltage is a helluva lot less than the rated coil voltage.? The 6 msec they quote is for the actual pick up voltage.? When run at rated voltage, the actual operate time is 2 msecs on a GH1.?
If u need any help with this, lemme know.?
