Conflict Monitor - 18 Channel Enhanced Diagnostic - TYPE 170 and TYPE 179 Controllers

Conflict Monitor - 18 Channel Enhanced Diagnostic - TYPE 170 and TYPE 179 Controllers


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

Product Information

The Model 210B is the new standard of diagnostic capabilities for 18 Channel, Type 170 and 179 Conflict Monitors. Enhanced signal monitor, Model 210B is a cost effective solution to detect, diagnose  and safeguard your traffic signal equipment.

Conflict Monitors can be installed in new systems or upgrade the capabilities of older basic monitors used in Type 170 and 179 units operating in the field. Model 210B meets or exceeds Caltrans specifications for 18 Channel Conflict Monitor and is made in the United States.


  • Operating temperature conditions and line voltage are automatically recorded with events.
  • Load Management System capability of current monitoring, comparison of Load Switch input status to output status and Flasher Unit monitoring.
  • DIP Switch selection of Enhanced Monitoring Functions
  • Event Logging of 300 records retained through power failure
  • No Input / Absence of Red Monitoring, Minimum Yellow Time Monitoring, Transition Sequence Monitoring and Multiple Indication Monitoring.
  • Compatibility with all TYPE 170 and TYPE 179 Controllers
  • RS232 Serial Communications Capability
  • Microprocessor based design
  • RMS voltage monitoring (not peak-voltage-only)
  • Self-diagnostics
  • Internal monitor Hardware and Software Watch Dog
  • Real Time Clock
  • Enhanced Monitoring including Red Monitoring
