Solid-state relays are available in different forms – from modular terminal enclosures to plug-in bases for terminal rail mounting. For contactless switching and amplification of digital signals in automation engineering Based on a wide enclosure platform, Weidmüller has the optimum component for every application. Weidmüller solid-state relays are available with nominal voltages of 5 to 230 V on the input side. Optional DC and AC outputs enable the switching of loads in the most diverse applications.
Relay modules are universal isolators in electrical automation. Requirements for them often differ, due to their widespread uses. With the development of our TERMSERIES relay modules and solid state relays, we have taken these practical requirements as our highest benchmark. Depending on the application, you can choose the product with the fixed-voltage inputs or with the variable-voltage input – which is currently a unique feature in this thin 6 mm terminal block format. Our practical development reveals a high-quality design that has no sharp edges, a large number of variants with screw and tension-clamp connections, and a clear status display even in difficult viewing conditions. The outline symmetry of the products enables every possible installation. Unlimited cross connectivity, even across partitions, assures versatile usage for your application regardless of how unusual your needs may be.
The TERMOPTO solid-state relay module is used in industrial applications where electrical isolation and signal conditioning without switching amplification is sufficient. The compact design in terminal-block format saves space on the terminal rail and offers the option of a pluggable cross-connection. The option between 10 input voltages and 3 output voltages as well as screw or PUSH IN connection enables 60 versions for various applications. The integrated protective circuit ensures sufficient protection in applications with ohmic as well as slightly inductive and capacitive loads. For purely inductive, capacitive or comparable loads with high switch-on and switch-off peaks, such as solenoid valves or filament lamps, ensure that the module is dimensioned appropriately or an additional safeguard is used.
The MICROOPTO range of products provide the user with the tried and tested characteristics of terminal blocks. Pluggable cross-connections and harmonised marking solutions packaged in a minimum design width. Best performance within a small footprint.

In many industrial applications, the switching performance of contactors is not sufficient to switch loads reliably in the long term, so heating elements on plastics machines, for example, are activated in cycles to regulate the heating output. Electromechanical elements soon reach their performance limits. Switching noises produced by contactors in refrigeration technology, plant engineering and processes, where people work in close proximity to machines, often have a negative effect on concentration or are considered disturbing. This is where Power solid-state relays, with their wear-free and silent switching or regulating function, prove useful.
Based on a wide range of enclosures, Weidmüller offers the optimum component for every application. On the input side, the solid-state relays are available with rated control voltages of between 3.5...240 V or an analogue input of 4...20 mA.
Optos are available in different forms – from modular terminal enclosures to plug-in bases for terminal rail mounting. For contactless switching and amplification of digital signals in automation engineering Based on a wide enclosure platform, Weidmüller has the optimum component for every application. Weidmüller solid-state relays and optos are available with rated voltages of 5...230 V on the input side. Optional DC and AC outputs enable the switching of loads in the most diverse applications.
