2 Channels 12V High Level Relay Shield With LED

2 12V high-level relay shield with LED
product manual:
1, the module conforms to the international safety standards, the control area and the load area has the isolation groove;
2, using double-sided FR-4 circuit board design, high-end chip production process;
3, the use of loose music authentic relay control;
4, with power and relay action instructions, pull bright, off does not shine;
5, the signal input has a high signal, normally open side normally open;
6, the relay can directly control a variety of devices and loads;
7, there are two normally open and two normally closed contacts;
8, blue KF301 terminal connected to the control line more convenient.
9, module size: 41x41x18.5mm; net weight: 28g
Third, the technical parameters:
Relay version Static current Maximum current Trigger current Trigger voltage
??5V 5mA 190mA 2-4mA 0-1.5V
??12V 5mA 80mA 2-4mA 0-4V
??24V 5mA 50mA 2-4mA 0-8V
Module Interface:
First, enter the part:
VCC: Connect the positive power supply (depending on the relay voltage)
GND: Connect the negative power supply
IN1: single relay module signal trigger side
IN2: Two-way relay module signal trigger side
2, the output part (relay output):
1, NO1: normally open one-way relay interface, before the relay pull-in, after a short circuit with COM1
2, COM1: 1 relay commonly used interface
3, NC1: 1 relay normally closed interface, short circuit before the relay and COM1, unplug the vacant
4, NO2: 2-way relay normally open interface, pull the relay before closing, and COM2 circuit
5, COM2: 2 relay commonly used interface
6, NC2: 2-way relay normally closed interface, short-circuit relay and COM2, unplug the idle
?
High and low meaning:
High-level triggering refers to the positive voltage of the VCC terminal and the trigger terminal is connected to the trigger mode, when the trigger has a positive voltage or trigger voltage, the relay is pulled.
Low level triggering refers to the negative side of the GND, the trigger side connected to the trigger mode, when the trigger side of the voltage is 0V or low voltage can trigger, the relay is pulled.
Electrical parameters
Voltage version Static current Operating current Trigger voltage Trigger current
??5V 4mA 135mA 2-5V 2mA
??9V 5mA 105mA 4-9V 3mA
?12V 5.5mA 95mA 4-9V 3mA
?24V 12mA 75mA 8-24V 3mA
Relay contact capacity: 250V 10A (AC) or 30V 30A (DC) (theoretical maximum load capacity), it is recommended that the AC below 1500W, then below 200W.
