Two TRANSCO SP4T coaxial relays bought at Western Test Systems
TRANSCO 14100 14300 14701 14704 Data sheet 1 2
Warning: Do not connect the coils in series (56V DC). I did that with these two 14300īs and managed to burn the position 4 coil on both. Because the position 4 coil is doing reverse action (i.e. normally closed) it is not identical to the other coils.
