Dual Channel 5V SSR Solid State Relay Module with Fuse, 250V 2A Low Level Trigger

Solid State Relay 240V 2A

Enhance your electronic projects with our top-quality solid-state relay, designed for optimal performance and reliability.

Key Features:

• Output: 240V 2A with resistance fuse
• Input Power: 5V
• Input Control Signal Voltage:
  • 0-2.5V: Relay ON (Low-level)
  • 3.3-5V: Relay OFF (High-level)
• Convenient 2.54CM pin and blue KF301 terminal for easy control line connection

Input Section:

• DC+: Connect to the positive pole of the power supply (relay voltage)
• DC-: Connect to the negative pole of the power supply
• CH1: 1-way relay module signal trigger terminal (low-level trigger)
• CH2: 2-way relay module signal trigger terminal (low-level trigger)

Triggering Explained:

• High-Level Triggering: Forward voltage between the signal trigger terminal (IN) and the negative pole of the power supply. Typically, the positive pole of the power supply connects to the trigger terminal to activate the relay.
• Low-Level Triggering: Voltage at the trigger terminal is lower than the positive pole's voltage, causing the relay to activate. The negative pole connects to the trigger terminal for activation.

Electrical Parameters:

Version	Voltage	Quiescent Current	Operating Current	Trigger Voltage	Trigger Current
1-way	5V	0mA	13.8mA	0-2V	2mA
2-way	5V	0mA	26.8mA	0-2V	2mA

Product Instructions:

Ensure the power supply to the module is DC and matches the relay's voltage for correct operation.

Package Includes:

• 1 x 2-way relay module
