The 820A Series from IDC Multisonics represents the most advanced, versatile, and effective traffic controllers in the industry. To enhance flexibility, the 820A will support various firmware configurations which fulfill the demand for expanded features and options.

IDC's 820A VMS controllers feature an alphanumeric user-friendly display for easy data entry, as well as a Graphic Intersection Display of NEMA-required items viewable during editing of the 820A's database. Programming has never been easier with the menu-driven selections in traffic engineering terms.

Specifications

820A VMS

The 820A VMS is designed for use in a system controlled by the IDC Multisonics VMS-330. The VMS-330 provides centralized control, monitoring, and database management for up to 256 controllers such as the 820A VMS. Detector switching, extension, and delay are internally controlled. Each detector input on the 820A VMS may be used as a Type 3 detector input. Dimming is activated by either time clock or external input. The 820A VMS features MUTCD flash, and offers time based coordination using 150 events. The events are structured into 16 day plans, 10 week plans, one year plan, 30 exception days, and 16 holidays. In addition, two special function outputs may be controlled by time clock.
