1 Functional characteristics 1) The main power: 12V/24V DC power supply; 2) high performance of the SCM control; 3) Two dial switch, can be used as two input points for the special-purpose function set; 4) Two LED respectively the display of the power and operation of the status; 5) 4-channel optically isolated SCR output, can control the working voltage of AC 220V directly, the maximum output current is 15A; 6) 4-channel optically isolated SCR output divided into two groups, can respectively wiring, each of the group can be used to control the difference load, such as contactor, a variety of bulb, heating wire, electric motor and all kinds of electricity the load; 7) The SCR output use of specialized chip zero-crossing trigger, produced minimal harmonic, all of the SCR are having overvoltage and overcurrent protection of the circuit and high-frequency filter circuit; enabling the system with high stability. and extremely long working life. 8) the working temperature range of the control the panel is (-10 to +85 ° C); 9) each of the the SCR output the panel are having specialized anti-lightning circuit; 10) there is a channel RS232 interface can conmmunicate with the computer and other host computer to constitute of a large communication system. 11) under the circumstance of plus RS232 to RS485 module of more than one controller to constitute RS485 network communication system.2. Specification 1) working temperature: -10 ~ +65 ° C; 2) storage temperature: -20 to +80 ° C; 3) humidity: 5 ~ 95% non-condensing; 4) power consumption (no peripheral equipment): +24 V@0.2A (typical values)3. Use 1) can be used to control the contactor, a variety of electric lights, heating wire, electromoter of the large power the load;
