Relay module Optocoupler isolation trigger Bipolar 12V (538)

Detail Relay module Optocoupler isolation trigger Bipolar 12V (538)

Using high-quality genuine ultra-small size power relays, large load current 5A/250V, the size of the entire relay module: 42.5mm length X 14mm width X 20mm height, which is half of the ordinary relay module. The trigger end of the module can support high-level trigger and low-level trigger, without manual setting, automatic identification (adaptive), and the relay circuit behind the 12V power supply is fully isolated with optocoupler without any connection. The module uses a fully isolated design, high and low level can be triggered, compatible with many interfaces, suitable for single-chip control, equipment control, household appliances, security equipment.

1. Interface description:
1. V+ is the positive terminal of the relay's working voltage of 12V;
2. GND is the ground, connected to the negative terminal of the 12V power supply;
3. Two INs are signal input terminals, both high and low level, both positive and negative can be triggered. The signal source cannot be connected to V+ and GND;
4. SW1 and SW2 are normally open ends. SW1 and SW2 are disconnected before the relay is closed, and SW1 and SW2 are connected after being closed;

2. Electrical parameters:
1. The working voltage of the relay is 12V;
2. Dimensions (length, width and height): 42.5mm X 14mm X 20mm
3. Relay load capacity: AC (alternating current) 250V/5A, DC (direct current) 30V/5A;
4. Trigger level: trigger voltage 2.5V~5V, trigger current 5mA;
5. Indicator light, the red LED light is the power indicator light, the module will light up when the module is powered on, and the blue LED light is the relay pull-in indicator light, when it is off, it lights up;
