Relay modules
Solid state relays
Wieland solid-state relay modules, the
powerful addition
Solid-state relays are used in the same
way as electromechanical relays as a
connecting element between field devices
and electronic control and signalling
equipment. These modules can offer
additional functionalities to the switching
tasks that are required during processing.
The core characteristics of the solid-state
relays are:
Wieland offers a full range of solid state
relay modules with the properties outlined
above. Depending on the required
applications, a superior selection of relay
modules are available with various
operating voltages, output arrangements
and housings.

Overview of the technical data
Input circuit/control side
Wieland solid-state relays can be
controlled with direct or alternating
voltage, depending on their type. Each of
the modules contains a suppression
circuit against polarity reversal and an LED
for status display in the input circuit.

To ensure safe operation of the relay
the residual voltage in the control circuit
must not exceed 5% DC or 15% AC of
this operating voltage as specified in
VDE 0435.
Output circuit/loadside
A solid-state relay for either DC or AC
loads can be selected depending on the
application. Also with DC outputs there
are 2 types of connection available.
2 wire output
3 wire output, with negative switching

To guarantee error-free operation it is
important to select a relay with a rating
that meets the voltage and current
requirement and also to add a protective
circuit to the output as shown in the block
diagram above - such as a varistor or RC
element.
If a solid-state relay is operated with an
inductive load, the load must be equipped
with a protective suppression circuit such
as a free-wheeling diode. In all cases, it
must be ensured that the protection level
of the protective device lies below the
respective off-state voltage of the relay.
Block diagram of AC output
Solid state relays for the AC loads
incorporate a triac as the switching
element. A triac is a zero voltage switch
and is used to avoid high inrush and back
EMF peaks by connecting the load at zero
voltage and disconnecting the load at zero
current.
As for D.C. loads, care should be taken
that the protection level of the protective
measures lies below the off-state voltage
of the Triac.
