Relay Module 1 Channel 5V Active High Trigger

Description

Relay Module 1 Channel 5V Active High Trigger The Relay Module 1 Channel 5V Active High Trigger is a compact relay module engineered for seamless integration with microcontroller systems such as Arduino and Raspberry Pi. It accepts a 5V TTL active-high trigger and incorporates a transistor driver with pull-down circuitry to prevent false triggering due to floating inputs. The module includes both Normally Open (NO) and Normally Closed (NC) contacts capable of handling AC or DC loads, along with LED power indicator ensuring clear operational feedback. Features Accepts 5 V TTL control signals with active-high triggering. Includes both NO and NC relay outputs to offer flexible usage scenarios. Onboard transistor driver enables low-impedance control, reducing load on the microcontroller. Pull-down resistor ensures stable off-state when the control pin is left floating. Power LED indicator for clear operational feedback. Designed to switch both AC (e.g. mains appliances) and DC loads, broadening applicability. PINOUT Specification Parameter Value Trigger Voltage 5 V TTL (active-high) Control Input VCC, GND, Signal Load Outputs NO, NC, COM Indicator LEDs Power and Relay activation Driver Type Transistor with pull-down resistor Supported Loads AC and DC switching Board Dimensions 33mm x 25.5mm Applications Home automation systems.
