The ComNet
The FDX57 series is tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment. This model features Voltage transient protection on all power and signal input/output lines, which provides unconditional protection from power surges and other voltage transient events.
