Distributed safety: Turck's TBPN and TBIP safety modules also control safety functions autonomously from the field

Ethernet Safety I/O Modules in IP67

Turck's TBIP and TBPN full safety block modules control safety applications directly from the field and thus simplify modular machinery

The robust block I/O modules TBPN for Profisafe and TBIP for CIP Safety provide safety input and output signals directly from the field to the safety controller. The modules can alternatively be used as decentralized safety controllers in the field. This function optimizes modular machinery and also applications in which long bus cycle times to the central controller would require greater safety distances.

Your Benefits

  • Short cycle times in large systems due to the decentralized control of safety applications
  • Minimum mechanical installation effort, no need for a control cabinet
  • Consistent modularization with decentralized intelligence
  • Maximum availability thanks to fully encapsulated, shock and vibration-tested modules

Test safety functions offline to reduce commissioning times

Safety functions can also be already tested offline with the local safety controller function before the machine or the machine module communicate with a central controller. Commissioning work is considerably faster when the devices are used in combination with a custom web server.

Universal I/Os increase flexibility

The new block I/O devices provide four safety inputs and four universal inputs or outputs (FDX) in the field. The flexibility of the FDX ports in particular enables optimum coverage of the individual safety signal requirements of any application. The modules can be used for applications up to PL e, category 4, in safety circuits up to SILCL 3. Actuators are provided with 2 amps per output, with up to 9 amps in total. With protection to IP65/IP67/IP69K and an extended operating temperature range from -40 to +70 °C, the fully potted block modules can withstand the harshest environments.
