SSR60-固态继电器

SSR60-DA Solid state relay: 1.Description: Solid state relay is called "SSR" for. ZG3 series product made by our factory is the latest non-contact electronic switch device with good ON-OFF performance. Its input end only requires tinny control current and can be compatible with integrated circuit of TT land CMOS, etc. The output return circuit adopts two way controlled silicon or big powder transistor to cut on or cut off the loading current. The photoelectric coupler is adopted between the input and output.Because solid state relay is a non-contact switch element made up of solid state elements. Compared with electromagnetic relay, it is more reliable. It has series advantages, such as long service life, little disturbance to surrounding and strong anti-interference performance, etc. It has wide application fields. And it tends to replace the traditional electromagnetic relay and further expands to the fields which traditional electromagnetic relay is not applicable for, like input/out0put interface of computer and program control, electric stove heating constant temperature equipment, digital control machine, remote control system., industrial automatic device, signal lamp, traffic lamp, stage lighting control equipment, instrument and meter, medical equipment, duplicator, color enlarger, and rubber & plastic machine, etc. In some special devices which require damp proof, fireproof and anti-corrosion, and under bad working environment, SSR has incomparable superiority in comparison with tradition with tradition electromagnetic relay. It is an ideal product to replace the older generations of products in relay family (EMR).2.Cautions while using 1). Over-current and loading short circuit result in SSR permanent damage. Quick fuse is one of the over-current protection methods. Small capacity may also adopt fuse. Over-voltage protection adopts parallel connection metal oxide varistor (MOV) as well as RC absorbing return inside SSR. The area size of MOV determines the absorbing power. The thickness of MOV determines protective voltage value. Generally, 220V series SSR may choose varistor of 500-630 VDC, 380V series SSR may choose varistor of 700-900VDC.2). If ambient temperature is too high, the loading capacity of SSR will descend. If the ambient temperature is high or the heat radiation is bad, the chosen SSR should be kept a certain margin.3). The resistance load should not surpass 60% of rated current. The inductance load should not surpass 40% of rated current. 3.Data: Function SSR Many kinds of input standards SSR With operation display Output Insulation Photoelectrical coupler Load Voltage 30 240VAC/90 480VAC/12-65VDCLoad Current 1 120ALeakage current 100VAC 5mA 200VAC 10mA VoRmVceo(V) 1000di/dt(A/us) 200dv/dt(v/us) 400I 2 t(A 2 s) 25-3000(Bigger current, bigger consumption)Tj(ºC ) Max.TJ(C) 100Input Input Voltage 3-32VDC/90-250VACInput Current <40mA Off Voltage 1VDC On Voltage 3VDC Off time 0.5ms DC/10msAC On time 0.5ms DC/10msAC Dielectric strength 50Hz,60S 2500VAC Ambient temperature -30ºC 80ºC(Under non-ice/dewfall condition) Coefficient of safety of working current Dissipative load is 60%/Inductive load is 40%
