The TIM 4R-IE offers all the advantages of the SIMATIC S7-300 design:

• Compact construction;
  double standard width of SIMATIC S7-300 SM modules
• Two 9-pin Sub-D connectors with a combined RS 232/RS 485 interface for connection to a conventional WAN via an appropriate modem
• Two RJ45 sockets for connecting to Industrial Ethernet or a IP-based network; designed for industry with additional fixing collars for connecting the IE FC RJ45 Plug 180
• 2-pin plug-in terminal strip for connection of the 24 VDC external supply voltage
• Front LEDs for indicating the module status and the communication
• Easy to mount;
  the TIM is mounted to an S7-300-mounting rail;
  if integrated as a CP into an S7-300 it is connected to adjacent modules by means of the bus connector supplied with the TIM. No slot rules apply. As a standalone device, it is linked via one of its Ethernet interfaces with one or more S7-400 CPUs or with one or more control center PCs.
• Can be operated in the expansion rack (ER) in conjunction with the IM 360/361
• Can be operated without a fan
