VLC-3.0 controller can be set 30 groups time (step) and in each step? the relay switch state can be set on/off. You can use external input voltage signal or switch quantity to achieve a variety of control modes. The controller can be used to control two solenoid valve linkage (control pneumatic equipment)? motor reversing? dual load intermittent work? etc.<br /><br />Features:<br />Digital LED display? set by three buttons? easy to use.<br />High-performance microcontroller? high process stability? digital display can be shut automatically? the min. operating current at 7mA/12V.<br />With reverse power protection? surge current shock.<br />Each group of relay has common and normally open? normally closed contacts? two sets of conversion.<br />30 groups time for setting? range: 0.1-9999 minutes adjustable? the total number of cycles are adjustable from 0 to 9999.<br />High level signal trigger launch? or forcing relay close/release.<br />All settings can be saved.<br /><br />Specifications:<br />Timing Range: 0.1-9999 minutes<br />Cycles: 0-9999 times<br />Operating Power: DC 10~16V<br />Coil voltage: DC 12V<br />Two set of conversion (normally open and normally closed)<br />Contact Load: 10A/277V AC or 10A/30V DC<br />DC Contact Resistance: &le; 100m믐 (1A 6V DC)<br />Mechanical Durability: 10 millions<br />Electricity Durability: &gt; 100?000 (10A-250VAC)<br />Normal Operating Current: 18mA/12V? when the display shut? the minimum current: 7mA/12V?
