Switching Relays

These relays provide intermediate or heavy

duty service in a wide variety of switching con-
figurations.

Relays with 24V control coils: Rl82J, R882J, R847A,
RA89A, RA832A, and R845A.

Relays with line voltage control coils: R482J.

Relays with internal 24V transformer: R182J,
RA89A, RA832A, R845A, and R847A.

Relays for use with an external 24V supply: R882J.

Heavy duty relays: R847J.

R847A has flexible internal leads to provide either
spst or spdt switching.

RA832A has contacts for low voltage and
millivoltage (Powerpile

®

) use.
