Additional Information

This unity hot standby processor by Schneider Electric comes from their highly regarded Modicon Quantum series. We know safety is a top priority for you and this CPU comes ready to go with the IEC 61508 certified Unity Pro XLS programming tool already installed. You can program a safety project without needing to connect any other equipment. Unity Pro XLS has two built-in programming languages, Function Block Diagram (FBD) and Ladder language (LD). 

With the safety architectures made possible by the 140CPU67160S, you have the power to increase the system availability, effectively eliminate process downtime, and set redundancy at every level, including, the power supply, CPU, wiring, I/O, and more. 

The 140CPU67160S is special because it is a double-slot module, holding the central processor unit function and the redundancy coprocessor in the same place. In the event of a failure, the redundancy coprocessor or “standby processor” takes over automatically, giving you peace of mind, easing stress, and mitigating problems.

The 140CPU67160S is specifically designed to seamlessly handle complex or difficult projects and has a detailed, intuitive display panel for your convenience. Each panel includes the following:

  • LCD cover
  • Easy lock/unlock key switch
  • Back-up battery insertion
  • Reset/restart button
  • Display with two lines that include 16 characters
  • Five-button keypad
  • RJ45 connector
  • Type B female connector for USB
  • Nine-way SUB-D female connector
  • Memory expansion card slots
  • COM and ERR LED’s
  • MT-RJ optical fiber connector
