D-SERIES relay modules were designed specifically for challenging industrial applications.
Many industrial applications voltages between 110 and 220 V
are used to control actuators. With load currents exceeding 100 mA
these high voltages produce arcing that causes a great deal of wear on the
relay contacts.
D-SERIES relay modules are specifically for universal usage
in a wide range of industrial applications. The D series are much more reliable
than conventional solutions, which minimises costs for maintenance and
replacement
Thanks to series connected contacts, built-in blow magnets and low-wear
contacts, arcing is effectively
suppressed with D-SERIES products – resulting in a noticeably longer service life.
