Contactors & Relay Modules

Contactors and relay modules are the switching layer between low-voltage control systems and real-world loads: gates, barriers, lighting, locks, pumps and motors. In security installations they let an access controller or alarm panel switch equipment safely without exposing the controller to high currents.Select a module by coil voltage (12 V and 24 V DC are standard in security systems), contact rating in amps, the number of changeover contacts and the mounting style – DIN-rail modules keep cabinets tidy. Time-delay relays add functions such as automatic gate closing. These modules are frequently used together with <a href="/product-category/barrier-gate-automation/" rel="nofollow noopener">barrier and gate automation</a> and are best installed in proper <a href="/product-category/electrical-installation-boxes/" rel="nofollow noopener">installation enclosures</a> for protection and serviceability.
