Industrial 4-Channel Relay Module - 4-channel module with relays

A power module for the Pimoroni Yukon platform that allows independent control of two high-current outputs within a voltage range of 5 to 17 V. Built-in diodes and chokes enable excellent handling of inductive loads such as pumps, fans, and solenoids. Each channel can also operate in PWM mode, allowing for smooth power regulation in slow-response devices. The module supports a total current of up to 15 A and includes temperature sensors and a "power good" signal. Pimoroni PIM692
