Pulse transformer technology for isolating I/O signals
offers significant advantages over optical isolation and
electromechanical relays. Most notably, pulse transformer
I/O modules provide higher transient immunity
and high input-to-output isolation.
The high transient immunity means the Weidmuller -
Delcon I/O modules are ideal for I/O applications where
electrical noise is a problem. No additional suppression
components are needed even when used with long
unshielded signal cables, inductive loads or ‘noisy’
power lines.
The limitations of optocoupler based solid-state relays
disappear when pulse transformer I/O modules are
used. For instance, the standard AC output module SLO
24TR has near zero leakage current; requires no minimum
load; can be used with any power factor 0 to 1;
is rated for both general use and inductive loads at 3A;
and is immune to both load line and signal line spikes.

DELCON Series Relays
Innovative—
Finnish – Delcon
Delcon has manufactured pulse transformer technology based
solid-state relays for demanding industrial applications since
the end of the 70´s. Delcon has its product development and
assembly near Helsinki, Finland. The extremely high quality of
the products is guaranteed by the design, the choice of the
right components, good workmanship and 100 % testing.
Avoid production downtime
Customers choose Delcon because of reliability, safe operation
and costs savings in maintenance due to fewer unexpected
production stoppages.
Add reliability to
a control system
Delcon Series relays improve the reliability of the whole control
system. The exceptionally clear function and condition indication
of Delcon Series relays is based on a unique current-voltage-
hysteresis that guarantees 100 % switching and signalling even
under the worst conditions.
AC relays are immune from interference and
guarantee safe switching and reliable signal
