Fuzion Z9

Smart Traffic Controller


All in one signal control with

AC drivers & integrated CMU


The Fuzion Z9 is a fully integrated traffic controller,including 24
AC signal outputs with a fully integrated CMU (conflict monitor
unit) with 16 traditional detector inputs and RS485 sensor inputs.

The highly integrated design comes equipped with Ethernet
ports, WiFi and LTE for network communications, along with four
USB for expansion and interfacing. Additionally it supports DSRC
for connected vehicle applications.

Capable of operating as a fully solar powered traffic signal.

Functional Specifications

  • Load switch circuits: 24 AC 4A circuits (expandable via USB)
  • Radar/Video channels: Four RS485 isolated serial channels
  • Power monitor: Supply current and voltage monitoring
  • Time source: Integrated GPS or network NTP
  • Packet communications: Two ethernet, WiFi and LTE cellular
  • Interfaces: Four USB and Bluetooth
  • Connected vehicles: 23dBm 802.11p DSRC Transceiver
  • Display: 7″ Capacitive color touch screen

Integrated Learning Conflict Monitor

All circuits are driven by a dedicated output processor with built-in flash transfer relays for red flashing fault.

Conflict is triggered by:
• Green / yellow phase conflict
• Short green, yellow or red
• Line voltage differs from output request
• Low or high supply voltage or frequency of supply voltage
• Thermal overload on load switches or too high of current draw

Conflict is reset on local/remote request or optionally if auto mode and conflict is cleared for a minimum duration and retries.

Capable of learning the conflict matrix by observing the operation of the traffic signal configuration before being deployed.
