Weidmüller has expanded its TERMSERIES family of products to include high-performance variants capable of reliably and durably switching inductive and capacitive loads. Featuring a compact design and a slim width of just 12.8mm, the variants fit anywhere on the DIN rail. They can instantly switch the full 16A load current thanks to the integrated cross-connection system.
The first product in the range is a 16A 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 5VDC to 230VAC/DC. The second solution is a 16A HC 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 16A HCP 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 24VDC and a multiple voltage input of 24-230VAC/DC.
Weidmüller has also made a couple of amendments to its range. The TOS/TOZ variant, which is a 12.8mm solid-state relay with an increased DC switching capacity of 5A, 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 6mm 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 24VDC and a multi-voltage input, while the TRS/TRZ AgSnO module features a 24VDC input.
