4-Channel SPDT Relay HAT for Raspberry Pi

Note When carrying a heavy Inductive load for a long period of time, the on-board MCU might be down and a reset procedure is needed. The 4-Channel SPDT Relay HAT for Raspberry Pi utilizes four high-quality SPDT (single pole - double throw) relays and provides NO/NC (Normally Open/ Normally Closed) interfaces that can control the load of high current. This means it could be a nice solution for controlling devices that can't be directly controlled by the I2C bus. The standardized shield form factor enables smooth connection with a Raspberry Pi and it also has four LED indicators that show the on/off state of each relay. Features High-quality SPDT (single pole - double throw) relays Compatible with Raspberry Pi 1/2/3/4 I2C interface with three hardware SW1 (1, 2, 3) to select the fixed I2C-bus address Relay screw terminals for easy connection Standardized shield shape and design LED working status indicators for each relay COM, NO (Normally Open), and NC (Normally Closed) relay pins for each relay Specifications SpecificationDetails Power Supply 4.75 ~ 5.5V Max Switching Voltage 30VDC/ 250VAC Max Switching Current 15A Frequency 1Hz Dimensions 91.2 x 56 x 32mm Hardware Overview Part List 1 x 4-Channel SPDT Relay HAT for Raspberry Pi
