Siemens Coupler For Use With Max.4 PN-Controller, Max 24V DC Voltage Rating, 16 Coupling Modules - SIMATIC Series - 6ES7158-3AD10-0XA0 Use this PN/PN coupler from Siemens to enable safe and efficient data transfer between two PROFINET (PN) controllers. You can use it to connect one Ethernet subnet to another to transmit a high volume of data. It can also exchange data between a maximum of one 4-PN controller per subnet. This device has two BusAdapter connector ports, one designed to receive data and the other designed to transmit it, for the automated control of your system. This coupler is ideal for use in data centres or computer programming environments. • Compact dimensions of 100 (W) x 117 (H) x 74mm (D) for mounting in tight spaces
• Easy installation via an integrated mounting rail
• Wide operating temperature range between -30°C and +60°C for use in harsh environments
• Multi-coloured LED light indicates system status at all times for easy monitoring
• Stored energy of 10ms (metres per second) for backup in the event of a mains power failure What’s a control coupler? A control coupler is used to connect two devices in an electrical circuit or system. This coupler is a PN/PN coupler, meaning it has two PROFINET interfaces, each connected to a subnet. It's used for exchanging data across your system.
