6GK7243-1BX30-0XE0 CP 1243-1 Telecontrol Processor for S7-1200 | Siemens

The Original New Siemens 6GK7243-1BX30-0XE0 SIMATIC CP 1243-1 Communications Processor is a powerful telecontrol and security module for the S7-1200 controller. It provides an additional, dedicated Ethernet interface for network separation and enables secure connection to control centers via telecontrol protocols. With integrated firewall and VPN (IPsec) security, it protects S7-1200 stations and downstream networks against unauthorized access and encrypts data transfers against manipulation and espionage.

Core Engineering Highlights:
10/100 Mbps additional Ethernet interface | 1x RJ45 port | Telecontrol protocols: DNP3, IEC 60870‑5‑101/104, TeleControl Basic | Integrated Stateful Inspection Firewall and IPsec VPN | 5V DC from S7-1200 backplane bus | 250 mA current consumption | 1.25 W power loss | 30 mm width | 0.122 kg | –20°C to +70°C operating temperature | IP20 protection
