Relay Module 4 Channel Switch Input and Output Circuit Control Board Component DC 7 24V

Feature: 1. DC7‑24V power input socket, low power consumption and high accuracy, can be sucked 100,000 times continuously. 2. PCB board is adopted, which has higher density, and the layout of the whole module is reasonable and beautiful. 3. The relay module has a diode leakage current protection function, and the response time is short. 4. Realize 4‑channel optical coupler input signal detection, which can be used for digital detection or power control situations. 5. The relay module is often used in automated control circuits, and plays the role of automatic adjustment, safety protection, and conversion circuit. Specification: Item Type: Relay Module Material: PCB Working Voltage: DC 7 24V Purpose: To realize the detection of 4 channel optical coupler input signal and 4 channel relay output, which can be used for digital quantity detection or power control situations. .
