The cable length shall not exceed 2000 ft. (609.6 m) for the operational baud rate of RS-485 communications (9.6 Kbps).
If 12 VDC is being supplied for the CTAD then the cable length shall not exceed 110 ft. (33.5 m).
If 24 VDC is being supplied for the CTAD then the cable length shall not exceed 600 ft. (182.9 m).
Both communication and power conductors can be bundled together in the same cable as long as the abovementioned conditions
are met.
In the case of a retrofitted CTAD that has both RS-485 and RS-232 lines, the cable shall be the Wavetronix SS-708-xxx or an equiva-
lent cable.
If a cable length of 600 ft. (182.9 m) to 2000 ft. (609.6 m) is required, the power cable shall be an ANIXTER 2A-1402 or equivalent cable
that meets the following requirements:
• 10 AWG conductor size/gauge
• 2 conductor count
• Stranded cable type
• Bare copper material
• 600 V range
• 194°F (90°C) temperature rating
• PVC/nylon insulation material
• PVC—polyvinyl chloride jacketing material
• 25 A per conductor
Both communication and power conductors can be bundled together in the same cable as long as the abovementioned conditions
are met.
2.4 In-cabinet interface equipment. The CTAD shall be installed using the Click 600, 650 or 656 cabinet interface device, a Wavetro-
nix preassembled backplate, or an equivalent that provides input power surge suppression, sensor cable surge suppression, AC to DC
power conversion (if necessary), and terminal blocks.
2.5 Lightning surge protection. The CTAD has onboard surge protection; proper grounding is required for effective surge protection.
Consult the article titled Intersection Grounding Schematics in the knowledge base on the Wavetronix website for more information.
Appropriate lightning surge protection shall be installed in the traffic cabinet to protect the cabinet equipment. These lightning surge
protection devices shall meet or exceed the IEC 61000-4-5 Class 4 specifications. The Wavetronix Click 222 and Click 65x devices
both meet those standards. The lightning surge protection unit supplied shall be physically compatible with the cable provided.
2.6 Power supply. The CTAD shall be installed using the Click 65x, the Click 202 or Click 204 (included on the Wavetronix preassem-
bled backplate), or an equivalent AC to DC power converter that meets the following specifications:
The power converter shall be power rated at 15 W or greater at 77°F (25°C) and 10 W or greater at 165°F (74°C).
The power converter shall operate in the temperature range of to -29°F to 165°F (-34°C to 74°C).
The power converter shall operate in the humidity range of 5% to 95% at 77°F (25°C) non-condensing.
The power converter shall accept an input voltage of 85 to 264 VAC or 120 to 370 VDC.
The power converter shall operate at an input frequency of 47 Hz to 63 Hz.
The power converter shall produce an output voltage of 24 VDC ±4%.
The power converter shall have a hold-up time of greater than 20 ms at 120 VAC.
The power converter shall withstand a voltage across its input and output of 2 kV. The power converter shall withstand a voltage
across its input and ground of 1.5 kV.
