Description
KAmodRPiRELAY is a relay outputs module for Raspberry Pi 3B+ or Raspberry Pi 4 model B. minicomputers. It is a universal functional expander for RaspberryPi and Raspberry Pi+ computers, equipped with two electromechanical relays and two transistor drivers (open-collector outputs) that buffer four GPIO lines enabling remote lighting control, switching on of heating and other tasks requiring remote access.
Features
- Compatibility with Raspberry Pi 1 B+, Raspberry Pi 2 Raspberry Pi 3, Raspberry Pi 3B+ and Raspberry Pi 4 model B.computers
- Four binary outputs, including:
- Two relay outputs
- Two transistor outputs
- Output states monitored by LEDs
- Extended I/O RPi minicomputer connector
- Screw terminals ARK
Technical Details
Relay outputs:
- Two SPDT outputs
- Maximum switching voltage: 250VAC/30VDC
- Maximum switching current (resistive load): 10A
- Recommended maximum load currents: 5A/240VAC, 5A/28VDC
Transistor outputs:
- Two open-collector lines
- Output circuits protected by diodes attached to +5V
- They can be used directly or to control two additional relays
- Maximum output current:
- 300mA/channel (when using one channel) or
- 200mA/channel (when using two channels)
The expander is compatible also with RaspberryPi 2/RaspberryPi + minicomputers.
