PLC-Multipoint T51 system is a stand alone short tunnel lighting control systems designed for any unidirectional, bidirectional, unidirectional ramp and bidirectional underpass lighting application. The T51 system has a VersaMax microprocessor based lighting controller used for night and contrast lighting control for short tunnel application. The purpose of the T51 system is to help provide safety by applying the most effective and effi cient way of controlling the light fi xtures resulting to visibility at vehicular tunnel approaches and interiors. The VersaMax controller has an option of using threePLC-Multipoint'
s sensors that receives a 4-20mA signal, such sensors are our MAS, TMAS and TLUM sensors. The system is costeffective and easily-confi gurable with programming and accessories. The system has four output channels per direction providing a night function as well as three daytime light level programmable according to the sensors input set points for accuracy. Optional alternationsequence of lights and night and day crossover method can be confi gure providing a long life span on any tunnel fixtures. The controller has a built-in input time delay and hold-on time eliminating any sudden surge in the fixtures of the tunnel.
