1/2/4/8-way 5V relay module optocoupler isolation high and low level trigger microcontroller
SPECIFICATIONS
Brand Name: other
Choice: yes
Condition: New
High-concerned chemical: none
Origin: Mainland China
Type: Relay
High and low level trigger selector:
1. When the jumper is shorted to L0W, it is triggered at a low level;
2. When a jumper is shorted to a high level, it is triggered at a high level.
One module description:
1. The module adopts authentic high-quality relays. The maximum load of the normally open interface is AC 250V/10A, DC 30V/10A;
2. Adopt patch optocoupler isolation, strong driving ability and stable performance; trigger current is 5mA;
3. Module operating voltage is 5V 12V24V
4. The module can be set to high level or low level trigger through jumper;
5. Fault-tolerant design, even if the control line is broken, the relay will not act;
6. Power indicator (green), relay status indicator (red)
7. The interface design is user-friendly. All interfaces can be directly connected through terminals, which is very convenient.
8. There are 4 fixing bolt holes, the holes are 3.1mm
Two module interface:
1. DC+: Connected to the positive pole of the power supply (voltage according to relay requirements)
2. DC: Connected to the negative pole of the power supply
3. N: High or low level control relay pull-in relay output:
1. N0: Relay normally open interface, relay hangs in the air before being attracted, and is shorted with COM after being attracted
2. C0M: Relay common interface
3. NC: Relay normally closed interface, the relay is shorted to C0M before being attracted, and is suspended after being attracted
