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

• Compact construction;
  double standard width of SIMATIC S7-300 SM modules.
• 9-pin Sub-D connector with a combined RS 232/RS 485 interface for connection to a conventional WAN via an appropriate modem.
• RJ45 socket as a further combined RS232/RS485 interface. The supplied RJ45/Sub-D interface adapter cable in turn provides a 9-pin Sub-D connector for connection to a conventional WAN via an appropriate modem.
• MPI (9-pin sub-D socket) for connection of the TIM as a standalone device to one or more S7-CPUs or control center PCs.
• 4-pin plug-in terminal strip for connection of the 24 V DC external supply voltage
• Front LEDs for indicating the module status and the communication
• The DCF77 adapter cable supplied with the TIM 4RD has a BNC connector for connecting the antenna cable.
• Easy to mount;
  The TIM is mounted on an S7-300 mounting rail;
  if integrated into an S7-300 as a CP, 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 its MPI with one or more S7 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
• A battery backup or memory module are not required
