Weidmüller Termseries 16 A HC and 16 A HCP relays

The Termseries range includes both electromechanical and solid-state relays equipped with one or two changeover contacts. Among the latest models are the 16 A HC and 16 A HCP units. These variants are equipped with relays that feature a contact arrangement and contact material designed specifically for industrial loads, extending the service life of the units by eliminating sparking during switch-on and switch-off.

Both the 16 A HC and 16 A HCP models can safely switch industrial loads of up to 16 A. The 16 A HC unit is a high-current, no-contact model. It is deployed to switch inductive loads such as solenoid valves, power contactors and motors. The 16 A HC is made using AgSnO contacts and features a large contact clearance. As contact is avoided, the 16 A HC is resistant to both loss of contact material as well as welding.

The contacts in the 16 A HCP are also made from AgSnO but with an advanced tungsten contact. It is suitable for capacitive loads where high in-rush currents occur such as LED drivers, light strips and switched-mode power supplies. For user convenience, both the 16 A HC and 16 A HCP are available with 24 VDC and multiple voltage input of 24-230 VAC/DC.

The DIN rail units have a slim 6.4 or 12.8 mm wide design. Both units have a distinctive status display due to the integrated fibre-optic technology that illuminates the ejector and ensures the safe removal of the switching element.
