Weike Electronics is a professional manufacturer and exporter that is concerned with the design, development production and marketing of arduino, 3d printers, raspberry pi and STM32. Our Dream is to make the best price and best quality produce for customers. So we would like to receive your valuable suggestions for our products and we can improve them for you.
12V relay contact capacity is 10A 250V, with optocoupler protection. Onboard power supply module does not need an external power supply. I / O port driver is active in low level. Used as a microcontroller development board, can be used as appliance control, also can be used as PLC output expansion.
Description:
The control signal voltage range: The trigger signal is low level 0-2V, high level voltage can not exceed 5V. Built-in optocoupler isolation, high anti-interference ability, stable performance, trigger current is only need 3mA. 1-16 channel optionally fully open / closed, or any channel. Output Type: AC 220V 10A direct connection or DC 30V 10A load. Each relay common terminal COM is independent, for access to different signals, each relay with both normally closed and normally open port. Each comes with relay action indicator, pull lit, disconnect extinguished. Humanized interface design, all interfaces can connect directly through the terminal leads, very convenient. It has four mounting bolts holes for easy installation. PCB board size: 180 x 90 x 20mm (L * W * H)
Parameter:
Supply voltage: 5V 12V DC Supply current: More than 200mA Each relay can load: 250V 10A (AC) or 30V 10A (DC)
Note:
Power supply need to meet the range, DC 12V. Power requirements according to wiring diagram, can not reversed. When using, LM2596S chip may have a fever, is normal, if long time using will appear normal heating phenomenon. Load power need to have certain margin for relay, it should avoid high-power (about 2000W). If working long hours, have a certain impact on the life of the product.
