Conflict Monitor - 16 Channel Enhanced Diagnostic - TYPE 170 and TYPE 179 Controllers

Conflict Monitor - 16 Channel Enhanced Diagnostic - TYPE 170 and TYPE 179 Controllers


Product Code: Model 210A
Made in USA #1Icon #5

Product Information

The Model 210A is the new standard of diagnostic capabilities for 16 Channel, Type 170 and 179 Conflict Monitors. Enhanced signal monitor, Model 210A is a cost effective solution to detect and safeguard your traffic signal equipment.

Conflict Monitors can be installed in new systems or upgrade the capabilities of older basic monitor used in Type 170 and 179 units operating in the field. Model 210A meets or exceeds Caltrans specifications for 16 Channel Conflict Monitor and is made in the United States.


  • Operating conditions of temperature and line voltage are readable upon request and are automatically recorded with recorded events.
  • Load Management System capability of current monitoring, comparison of Load Switch input status to output status, Flasher Unit monitoring.
  • Recorded Events 300.
  • No Input / Absence of Red Monitoring, Minimum Yellow Time Monitoring, Minimum Green Time Monitoring Transition Sequence Monitoring, Multiple Indication Monitoring.
  • RS232 communications for state-of-the-art programming/information retrieval.
  • Extended monitoring capabilities for safer intersection operation.
  • Motorola 68HC11 powerhouse microprocessor for reliable operation.
  • Firmware and hardware watchdog timers for most reliable failsafe operation.
  • Constant internal self-diagnostics while monitoring intersection safety.
  • Real time clock chip for accurate time stamping of recorded events.
  • Automatic front panel display of last fault and intersection status at time of fault.
  • Diode card read and displayed on computer to ensure correct permissives.
  • Meets or exceeds CALTRANS TYPE 170 requirements
  • Made in the United States
