Introducing a New Standard of Safety and  Diagnostic Capabilities

EDI continues to set the industry standard and provide traffic signal professionals with reliable, high quality mission critical component products that improve the performance and lifecycle of traffic control systems.

Providing the signal technician with a full intersection display and powerful monitoring and trouble-shooting tools helps ensure that cabinet malfunctions are detected, diagnosed, and repaired with confidence. True RMS voltage sensing makes the NSM-E series the most reliable signal monitor available.

Model Options:

  • NSM-6E 6 channel capability with EIA-232 Port
  • NSM-12E 12 channel capability with EIA-232 Port

(Note that the NSM-E series replaces both the SSM-E and NSM series products.)
