Bihl+Wiedemann Safety Technology

Safety Technology from Bihl+Wiedemann for large, distributed systems

Is your system large or heavily distributed? In this case, our Safe Gateways with Safe Link over Ethernet, e.g. as PROFIBUS..., is your first choice. In their maximum configuration these systems can cost-effectively and efficiently process up to 1922 safe 2-channel inputs, as well as control safe outputs either centrally or remotely.

Furthermore, we can provide just the right expansion modules for your system design. Additional information on safety solutions for large, medium-sized, and small systems can be found in the publication  "The coordinates of efficiency - savings in Safety Technology"

AS-i Safety Input Modules

Bihl+Wiedemann offers a customized safety concept for large, medium-sized, and small systems. In addition to Safety Monitors 

and safe output modules, important components of efficient safety concepts are safe input modules with IP 20 and IP 67 protection. For this purpose, Bihl+Wiedemann has expanded their comprehensive range of safe inputs by introducing an IP67/M12 AS-i safety input module for 4 / 2 dry-contact safe inputs

(BWU2631) and an IP 20 AS- safety input module for safety mat (BWU2661).

IP67, M12 for floating contacts with 4 / 2 safe inputs (BWU2631)

• Space-saving, cost-effective solution:
  4 / 2 dry-contact safe inputs (2 x BWU2284) in one module

• Ideal complement to the AS-i safety input modules for optoelectronic protective devices or for IP67 dry-contact safe inputs.

IP20 for safety mats (BWU2661)

• 1 safe input for safety mats 1.2 kΩ or 8.2 kΩ monitoring resistor
• 2 conventional solid state outputs:
  • Short circuit and overload protected
  • controls up to two indicator lights
  • Powered by galvanically isolated 24V

• Ideal complement to the AS-i safety input modules for optoelectronic protective devices or for IP20 dry-contact safe inputs.
