Relay 16 Channel 12V Module Board Optocoupler Power for Arduino AL10

RELAY MERK TONGLING 16 Channel 12V Relay Module Board Optocoupler Power for Arduino AL10 Description: 12V relay contact capacity 10A 250V, with optocoupler protection. Onboard power supply module does not need an external power supply. I / O port driver is active low. Used as a microcontroller development board module can be used as appliance control, can be used as PLC extended output. Module features: Control signal voltage range: trigger signal is low 0-2V; high voltage must not exceed 5V. Using the industry's top-quality isolation optocouplers, anti-interference ability, stable performance; trigger current is only 3mA. 1-16 can be any full on / off, or any road. Output Type: AC 220V 10A or directly connected to DC30V 10A load. Each relay common terminal COM are independent, user-friendly access to different signals, each relay are normally closed and normally open with the port. Each relay is equipped with motion lights, pull off, off off. Interface design humane, all interfaces are available through the terminal directly connected leads, very convenient. Has four mounting bolts holes for easy installation. PCB board size: 180MM (L) * 90MM (W) * 20MM (H) Electrical parameters: Supply voltage: 5V 12V (DC) Supply Current: more than 200mA Each relay can load: 250V 10A (AC) or 30V 10A (DC) Note: Power supply to meet the range DC 12V; Power requirements according to wiring diagram, is not reversed; Product LM2596S slight chip buck fever is a normal phenomenon, relays, long working hours have a normal fever phenomenon, are normal; Load power to give leave a margin relay load should avoid high-power (about 2000W) and long working environment, there will be some impact on the life of the product.
