Please note thevoltage: 5V, 12V, 24V
Sales of the company to develop 1, 2, 4, 8,12 road, all kinds of high/low level control relay modules, bidirectionaloptical coupling isolation relay modules and the timedelay/locking/timing/cycle time and other multi-function relay modules, 5 v, 12v, 24 v are available, welcome you the presence!
Isolation type 1 road power relay controlmodule, using high level signal trigger, and only 3 ma current drive for 30 arelay and control ability, module adopts quality goods of high quality powerrelay, the industry's top subminiature encapsulation light coupling, high powerhigh pressure triode, red, blue light signal, military level double-sided PCBboard, cloth plate considering comprehensive, stable performance and can bewidely used in all kinds of power control class.
1, the module used authentic quality relay, normally open interface maximumload: ac 250 v / 30 a, dc 30 v / 30 a;
2, using the industry's top quality subminiature light coupling, stronganti-interference ability, stable performance; Trigger current only 3 ma.
3, modules, working voltage is 5 v, 12 v and 24 v are available;
4, relay, high level suction, module contains a limited flow resistance, highlevel can be a DC +, can also be high SCM I/O port set;
5, fault-tolerant design, even if the control line is broken, relay will notmove;
6, the power indicator light (red), 1 road relay status indicator light (blue)
7, human interface design, all interface can be directly by terminal connectionleads, is very convenient
8, module size: 6.0 cm * 3.0 m * 2.5 cm (length * width * height)
9, is equipped with four 2.0 MM a fixed bolt hole diameter, convenientinstallation
The second module interface
Interface module control side: there are 4 line, all interfaces are terminalblocks, easy connection
1, DC + : external negative DC power supply (5 v, 12 v and 24 v moduleselection)
2, DC - : external negative DC power supply
3, VERF: photoelectric isolation control end reference ground wire, the signalcan in the user control panel power of the cathode
4, CH1: relay control interface, high level (as opposed to VERF) relay andaccordingly
Note: isolation or relay module is in order to adapt to the electromagneticenvironment is poor, the signal occasions with higher requirements, if you wantto achieve complete isolation effect, is the power of the user control panel(i.e. connect VERF reference power) and relay module power supply power supply(DC + / DC) should be separate, if the two power supply, total is short ofcomplete isolation effect, the user can choose our cheaper standard notisolated relay module.
Relay output: there are 3 line interface, all interfaces have terminal blocks
1 and NO: relay normally open interface, relay and impending, before and afterabsorption and COM sub
2, COM: relay public interface
3, NC: relay normally closed interface, relay and off with COM nipple, beforeand after the impending
