12V 16 channel relay module with Optocoupler(Blue Board)

12V 16 Channel PIC ARM DSP PLC Relay Module Interface Board with Optocoupler Protection LM2576 Power

SKU: SLY3015-12 Category:

Product Description

DESCRIPTION:
  • The power supply should meet the scope of use, DC 12V
  • The power supply is not required to be connected according to the wiring diagram
  • The product uses LM2596S step-down chip with slight heat, which is a normal phenomenon. The relay has normal heating phenomenon for a long time, which is a normal phenomenon
  • The load power should have a certain margin for the relay load. It should avoid high power (about 2000W) and work for a long time, which will have a certain impact on product life.
Application:
  • 12V relay contact capacity 10A 250V, with optocoupler protection. The onboard power supply module does not require an external power supply. The I/O port drive is active low.
  • Can be used as a microcontroller development board module, can be used as home appliance control, can also be used as PLC expansion output.
FEATURES:
  • Control signal voltage range: The trigger signal is low level 0-2V; the high level voltage cannot exceed 5V.
  • Using the industry’s top quality isolated optocoupler, strong anti-interference ability, stable performance; trigger current only needs 3mA.
  • 1-16 road can be turned on/off at will, or any way.
  • Output form: Directly connect AC 220V 10A or DC30V 10A load.
  • The common terminal COM of each relay is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port.
  • Each relay has an action indicator, which is illuminated and turned off.
  • The interface design is user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient.
  • There are 4 fixing bolt holes for easy installation.
  • PCB board size: 180MM (L) * 90MM (W) * 20MM (H).
Electrical parameters:
  • Supply voltage: 12V (DC)
  • Supply current: greater than 200mA
  • Each relay can be loaded: 250V 10A (AC)
