The module has 4 normally open (N/O) contacts and 1 normally closed (N/C) contact. This means it can switch circuits where 4 contacts close when activated (N/O) and 1 contact opens when activated (N/C). It operates with a supply voltage of 24 V DC. This means you need to supply 24 volts DC to the module for it to function correctly.
It can handle a switching load of up to 12 amps DC1. This indicates the maximum current that can be safely switched through each contact. The module has a width of 45 mm. This is useful for determining how much space it will occupy in your control panel or mounting enclosure. safety solutions provider since 2011, We offer pilz safety relays, safety sensor psen, emergency stop, two hand control, swicthes and more.
It uses plug-in spring-loaded terminals for connections. This type of terminal makes it easier to connect and disconnect wires quickly and securely. http://www.pilz.com The contact expansion module is used for expanding the number of contacts available in connection with safety-related control components. This typically means it is used in safety circuits where reliability and adherence to safety standards are crucial.
