The Siemens LZS:PT78740 is a robust plug-in socket designed to facilitate the secure and reliable connection of PT relays with 4 changeover contacts. This component is engineered to provide a screw terminal connection, ensuring a stable and durable link for your relay setup. With an IP20 protection class, it is suitable for general industrial applications where direct contact with the equipment is not an issue.
The socket is monostable, indicating that it will return to its original state upon the removal of power, which is ideal for applications requiring a stable and predictable response. The design of the switching function is a changeover switch, which allows for the control of two circuits with a common terminal. It is not positively driven, which means that the contacts operate independently, providing flexibility in various control and automation tasks.
The LZS:PT78740 is crafted with a standard snap-on socket base, allowing for quick and easy installation without the need for additional tools. It is compatible with a range of conductor cross-sections, both solid and finely stranded, with or without core end processing. The product is designed to accommodate conductor sizes from 1 to 2.5 mm², and it also accepts AWG cables from 18 to 14, providing versatility for different wiring requirements.
The socket's dimensions are compact, with a height of 74 mm, a width of 27 mm, and a depth of 41.5 mm, making it suitable for use in space-constrained environments. It can be mounted in any position, offering flexibility in installation. The ambient operating temperature range of -40 to +70 °C ensures that the socket can perform reliably in a variety of environmental conditions.
Overall, the Siemens LZS:PT78740 is a practical and efficient solution for those seeking a dependable and easy-to-install base for their PT relays in industrial settings.
