The module is developed on the basis of microprocessor Atmel and intended for distance control of road traffic. The module is united with similar modules in a daisy chain through RS-485-interface that allows to control to 215 road directions. All modules in this chain are interchangeable. Accepting a signal from the main operation box through GSM/GPRS-modem on RS-232-interface the module is capable to switch a movement direction instantly. The module controls three power directions: red, yellow, green. Its power contacts commutate to 600VAC 16À. The operating temperature is: up -40°Ñ to +105°Ñ. | ||||||||||
