16-channel 5V relay module 250VAC 10A

Product detailed description

The 16-Channel Relay Module 5VDC is a switching board suitable for controlling up to sixteen separate devices with higher voltage or current. Each relay channel can switch up to 250V AC / 10A, allowing you to control lighting, motors, fans, pumps and other appliances. The module is ideal for microcontrollers with 5V logic (e.g. Arduino), where logic level 0 (LOW) switches the relay. For 3.3V logic (ESP32 STM32), use a logic level converter

Key features:

• 16 independent relays – independently controlled by input
• Control voltage: 5V DC
• High load capacity: up to 10 A at 250 V AC or 30 V DC
• Each channel is equipped with LED indication of switching
• Optocoupler isolation for control electronics protection
• Common NO/NC/COM pins for each relay

Specifications:

• Relay: Songle SRD-05VDC-SL-C
• Number of relays: 16
• Control and supply voltage: 5 V DC
• Switched voltage: Up to 250 V AC / 30 V DC
• Max. switched current: 10 A
• Logic signal level: LOW = switching (typically < 0.8 V)
• Indication: LED for each channel
• Isolation: Optocouplers
• Board dimensions: 178 x 80mm × 17 mm

Package contents:

• 1 × 16-Channel Relay Module 5VDC

Comment:

• This product is not a standalone functional unit and may require professional installation.
• Working with 230 V AC voltage is dangerous - recommended for qualified personnel only.
• The relay is not designed for switching inductive loads without additional protection (e.g. RC element, varistor).
