Podazz 2 Pcs DC 12V Relay Module 2 Channel Relay Switch with Opto Isolated High/Low Level Trigger

Key features

• Dual-channel relay module adopts genuine and high quality DC12V relay and SMD optoisolator, supports high/low level triggering, which is widely used for controlling all kinds of AC/DC appliances and other high current devices.
• NO (normally open) Maximum load < AC 250V/10A, < DC 30V/10A. optoisolator trigger current: 5mA.
• The relay will not operate even if the control line is disconnected.
• Equipped with threaded terminal blocks and fixing bolt holes (diameter: 3.1 mm) on both sides for easy mounting.
• The relay module can be directly controlled by 12V logic signals from microcontrollers (8051, AVR, PIC, DSP, ARM, Pi, MSP430, TTL logic, etc.).

Product Parameters: Relay Type 12V Dual Channel TTL Gate Circuit - Static Current: 5mA Maximum current: 80mA - Trigger current: 3 - 5mA Trigger voltage (low): 0 - 4V 0 - 4V, trigger voltage (high): 4.5 - 12V No Maximum Load: AC 250V, 10A or DC 30V, 10A Power Indicator Green, Relay Status Indicator Red Dimensions (L x W x H): 51*41*19 mm Weight: 30 grams Operating Instructions: How to select high/low level trigger terminals S1 is the high/low level trigger selector terminal for channel-1 relay. S2 is the high/low level trigger selector terminal for channel-2 relay. When the jumper (COM) and the high level pin are shorted, the high level trigger operates. When the jumper (COM) and the low level pin are shorted, the low level trigger operates. Input connector: DC+ : Power positive (VCC, voltage = 12V) DC-: Power negative (GND) IN1: Channel-1 signaling trigger, control relay pickup by high/low level trigger IN2: Channel-2 signaling trigger, picked up by a relay controlled by a high/low level trigger Output Interface: NO1: channel-1 relay connection in normally open state (relay switch is suspended before pickup, after pickup the switch will be connected to "COM1") COM1: common interfa
