Relays and Solid-State Relays


Weidmuller now offers innovative, pluggable electromechanical and solid-state relays equipped with one- and two-changeover contacts in slim designs. TERMSERIES, The All-rounder, is housed in a slim 6.4mm or 12.8mm design with matching profiles that can be combined as needed based on application. These relays switch loads of up to 8A (resistive) at 250V.             

Engineers need high-density solutions for smaller electrical cabinets, professional handling, and comprehensive equipment identification options. Weidmuller’s TERMSERIES family of relays and solid-state relays solves this issue. Depending on the application, customers can choose between products with a fixed voltage input or Weidmuller’s unique multi-voltage input which allows conditioning signals from 24V up to 230V AC/DC with only one module. This multi-voltage input solution reduces the amount of spares necessary, simplifies installation and increases machine up time. 

Weidmuller’s TERMSERIES relay and solid-state relay modules require very little space on the mounting rail due to the extremely slim design. All one- and two-changeover relays, screw terminals­ and tension clamp modules feature cross connections on up to five levels across a variety of modules and across isolation plates with the easy-to-use jumpers reducing wiring time and cost. A distinctive status display with a LED that completely illuminates the ejector makes for quick and easy status identification and troubleshooting. The ejector also ensures the safe removal of the switching element. Weidmuller’s isolation plates, which are used to visibly group different signal voltages or currents, add labeling for a better overview or to electrically isolate two modules up to 400V. TERMSERIES relays are installer friendly and reduce the risk of incorrect wiring with the help of color-coded markings designed to be legible in different mounting positions. 

Colors are marked on the top of the module with blue for DC coils, red for AC coils and white for AC/DC coils. A wide operating temperature range from - 40° C up to + 60° C (-40° F/ 140° F) and international approvals, including cULus Listed, CE and GL, make Weidmuller’s large variety of TERMSERIES electromechanical and solid-state relays ideal for a broad range of applications worldwide.
