Frequently Asked Questions

• Q: What is the key advantage of the 140CRA93200 over single-port adapters?
  A: Its dual redundant F connectors allow connection to two separate coaxial cables, enabling fault-tolerant network ring or star topologies for maximum availability.
• Q: How many remote I/O modules can be connected to one adapter?
  A: A single drop headed by the 140CRA93200 can support a rack containing a maximum of 27 I/O expansion modules.
• Q: What kind of diagnostics does it provide?
  A: It offers comprehensive diagnostics including startup tests, continuous runtime monitoring, and checksum verification to quickly identify communication or module faults.
• Q: What is the purpose of the 500V isolation?
  A: This high voltage isolation protects the controller and adapter electronics from damaging ground loops or surges on the long coaxial cable runs.
• Q: Is this module suitable for harsh industrial environments?
  A: Absolutely. Its wide operating temperature range, high ESD/EMC immunity, and robust construction make it ideal for challenging plant floor conditions.
