Relays combine small size and high rat-
ings in a package designed for easy
heat sink or panel mounting. Standard
.187 push-on terminals assure quick
connection and are arranged to provide
maximum isolation between signal and
power circuits. Model S228C is a snub-
ber- less design for applications that
require low off-state leakage.
Manufactured in Crydom's ISO 9001
Certified facility for optimum product
performance and reliability.
