1-Channel Relay Module (5VDC – 250VAC/110VDC 10A)

Description

This 1-channel basic relay carrier module make it easy to control a single-pole, double-throw (SPDT) switch from low-voltage, low-current control signals. They can be used in interactive projects and can also be used to control lighting, electrical and other equipments. The module features an optocoupler for signal seperation for increased circuit protection.
The module is controlled with a 5V signal and a logic “LOW” to the control pin turns the relay ON.

Specification:

• Power Supply: External 5V
• Control Voltage: 5V
• Max Control Capacity:10A@250VAC or 10A@30VDC
• 2 mechanical relays with status indicator LED
• “NC” and “NO” ports for each relay
