Weidmüller has expanded its proven TERMSERIES family of products to include new, high-performance variants capable of reliably and durably switching inductive and capacitive loads. Featuring an especially compact design and a slim width of just 12.8 mm, the new variants fit just about anywhere on the DIN rail. They can instantly switch the full 16 A load current thanks to the integrated cross-connection system.
The first new product in the range is a 16 A CO contact, designed to switch industrial loads such as infrared heaters, pumps and small contactors. The AgNi contact material is suitable for switching low loads too. Weidmüller is offering a wide variety of input voltages for this module, ranging from 5 VDC to 230 VAC/DC. The second solution is a 16 A HC (high current) NO contact, which is deployed to switch inductive loads such as solenoid valves, power contactors and motors. Thanks to its AgSnO contact material and large contact clearance, this NO contact has proven itself to be resistant to both loss of contact material and welding. The third product is a 16 A HCP (high current peak) NO contact, which users utilise to switch capacitive loads such as LED ballasts, light strips and switched-mode power supply units. It is characterised by its AgSnO contact material and advanced tungsten contact, and thus prevents contact welding during switch-on processes involving capacitive loads. Both NO contacts are available with 24 VDC and a multiple voltage input of 24-230 VAC/DC.
Weidmüller has also made a couple of amendments to its range. The new TOS/TOZ variant, which is a 12.8 mm solid-state relay with an increased DC switching capacity of 5 A (previously 3.5 A), switches loads in a wear-free and quiet manner. There is also the TRS/TRZ AgSnO variant; users deploy the slim relay, which measures just 6 mm wide and is equipped with AgSnO contacts, to switch low capacitive loads, such as those that occur in LED lamps, contactors with a wide-range input and small switched-mode power supply units. The TOS/TOZ variant has 24 VDC and a multi-voltage input, while the TRS/TRZ AgSnO module features a 24 VDC input.
Weidmüller’s supply terminals, partition plates, cross-connections, other relay modules and solid-state relay variants are combined to form an extensive range of products designed to isolate and amplify signals. Power is available without restrictions, so you benefit from full switching current at each connection thanks to the internal cross-connection system. The special highlight is the 24-230 VAC/DC multi-voltage input, which can be used with all relay variants.
