TZT 5V 30A Two-way isolation relay module High/low level trigger 5V 30A 1-Channel Relay Module+Electronic With Optocoupler

1, the module used authentic quality relay, normally open interface maximum load: ac 250 v / 30 a, dc 30 v / 30 a;
2, using the industry's top quality subminiature light coupling, strong anti-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, high level 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 not move;
6, the power indicator light (red), 1 road relay status indicator light (blue)
7, human interface design, all interface can be directly by terminal connection leads, 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, convenient installation
The second module interface
Interface module control side: there are 4 line, all interfaces are terminal blocks, easy connection
1, DC + : external negative DC power supply (5 v, 12 v and 24 v module selection)
2, DC - : external negative DC power supply
3, VERF: photoelectric isolation control end reference ground wire, the signal can in the user control panel power of the cathode
4, CH1: relay control interface, high level (as opposed to VERF) relay and accordingly
Note: isolation or relay module is in order to adapt to the electromagnetic environment is poor, the signal occasions with higher requirements, if you want to 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 of complete isolation effect, the user can choose our cheaper standard not isolated 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 after absorption and COM sub
2, COM: relay public interface
3, NC: relay normally closed interface, relay and off with COM nipple, before and after the impending
