Title: Amperite 6C5 time delay relay Post by: W2INR on March 31, 2008, 09:22:09 AM I am looking for the pin out on this relay. It is the Old Buzzard amperite 6C5 delay relay.

page 1053 , 1962 Radio Master. 6C5, octal, 5 sec. delay, +/- 2 seconds at 20 deg. C. "standard radio octal" pin out. - pins 2 and 3 heater, 6.3vac; pins 5 and 7 are the contacts, normally closedin a 6C5. If the contacts were normally open it would be a 6N05. Interesting. Also no connections are shown on pins 1,4,6 and 8. Also a note on breaking DC current as follows: "When relay contacts open DC current above 50 volts, a condenser with a resistor in series with the condenser must be connected across the contacts. Following values approximate." "0. to 0.5 amps , 115 vac req's. 0.1uf.; 230 v req's 0.25uf. 0.5 to 1.5 amps, 115 vac - .25uf; 230 v - .25uf. 1.5 to 3 amps, 50 vac - 0.25; 115v - 0.5 uf and 230v -0.5uf Not mention of an accompaning series resistor value. Minature 9 pins are accompanied by a "T" in nomenclature, e.g., 6N05T. Standard pin out for the 9 pin minatures ; pin 1 and 6 heaters and pin 8/9 stationary contact, pin 3/4 moving contact. too bad it isn't a normally open Ry; you''ll have to be creative. ;D Well, probably TMI Rick Title: Re: Amperite 6C5 time delay relay Post by: W3RSW on March 31, 2008, 11:02:55 AM Oh,yeah, just noticed a whole other page devoted to Amperite relays.
Standard 2 to 10 second models including the 6C5, contacts rated at 3 amps AC / 115 vac ; 1 amp AC / 220 vac. DC voltage breakdown 250 v contact to contact. DC voltage breakdown 500 v heater to contact. R.

I would venture to guess the purpose of the resistor/capacitor network is to absorb the inductive kick that would cause the contacts to spark on break, when switching DC working into an inductive load. Wouldn't a reverse-polarity diode placed in parallel with the load accomplish the same thing? That network sounds very similar to the key-click filter commonly used for for cathode keyed transmitters. |
