30A 5VDC Power Relay Coil ( High/Low Level Trigger )

30A power relay coil 5VDC เป็นโมดูลรีเลย์ ที่ใช้แรงดัน 5V ในการควบคุม(สามารถใช้จากบอร์ด arduino ได้เลย) ใช้งานที่กระแสสูงสุดที่ 30A สามารถเลือกลอจิกในการทำงานแบบ active HIGH , active LOW ได้ โดยเลือก jumper บนโมดูลรีเลย์ 

Description:

• 1 channel 30A high current relay, supports high / low level trigger;
• Completely isolated with optocouplers, relay control terminal voltage can be powered independently;
• High quality 30A relay, normally open interfaces Maximum load: AC 250V / 30A, DC 30V / 30A;
• Using SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;
• Working voltage: 5V; 
• Module can be set high or low triggered by jumper
• Relay control terminal voltage and trigger terminal voltage jumpers can be powered completely isolated before and after class, to do after two different voltage requirements (such as a relay with 24V, trigger with 5V)
• Fault-tolerant design, even if the control line is broken, the relay will not operate
• Power indicator (green), relay status indicator (red)
• User-friendly interface design, all interfaces can be connected directly via terminal wiring leads, very convenient
• Module size: 50mm x 33mm x 24mm
• Net weight : 36g
• Static current: 5mA
• Maximum current: 190mA
• Trigger current: 2~4mA

Module interface:

• DC+: DC power supply module is positive (positive terminal voltage trigger)
• DC-: DC power supply module is negative (negative terminal voltage trigger)
• IN: Signal trigger terminal (same as the default trigger voltage power supply)
• JD+: Relay control terminal voltage positive
• JD-: Relay control terminal voltage negative 
• JD+ & DC+ shorted with a jumper cap, DC- and JD- shorted with a jumper cap, the same trigger terminal and relay control terminal voltage
• When the jumper is connected with the L side, IN terminal is low trigger, when connected H is a high end trigger
• Normally closed (NC): Relay normally closed terminal
• COM: Relay public terminal 
• Normally open (NO); Relay normally open terminal
