Wieland relay modules – the reliable
way to implement an application-
related interface
In the microchip age, many believed that
electromechanical relays would no longer
play a role. This is however far from the
truth. Switching relays have reliably carr-
ied out important tasks for many years,
working in a “symbiotic relationship” with
the electronics. Relays have
demonstrated a high degree of flexibility
over the years. The core characteristics
have been maintained or even improved
such as:
Wieland offers a complete range of relay
modules with a combination of properties
outlined above. Depending on the
required applications, relay modules are
available with various operating voltages,
contact arrangements, contact materials
and housing designs. Timer relays or
HAND-0-AUTO relays can be supplied in
addition to relays with pure monostable
functionality.

Control side – Suppression circuit
AC/DC relay modules are available. DC
relays are equipped with a polarised diode
and a free-wheeling diode in the input.
These functions are taken over by a
power rectifier in the case of AC or AC/DC
modules. All relay modules have an LED
for status display in the input circuit.

Control side – residual voltage
To ensure the safe operation of the relay
the residual voltage in the coil circuits
must not exceed 5% DC and 15% AC of
the operating voltage in accordance with
VDE 0435. Values above this will result in
the relay remaining closed after switch
off.
Residual voltages can occur from
semiconductor devices in circuit, induced
voltages from high current cabling or other
inductive or capacitive interference
factors.
Corrective measures may involve the re-
routing of cables away from interference
or the parallel connection of RC elements.
Load side – contact material
The contacts are used to route control
signals in a power range of mW up to
more than 1000 VA. The contact material
that is used is largely determined by the
load expected during operation
(particularly with regard to current carrying
capacity, switching frequency, operating
speed as well as any corrosive
environmental influences). Wieland uses
the universally accepted AgSnO contacts
for power ranges up to 1500 VA. In the
lower power range, the same material is
used but with a gold-plated finish.
Modules with gold-flashed AgCu contacts,
AgCdO or gold-plated AgNi contacts are
also available. Table 1 gives an overview
of other contact materials.
