Features 8 input and output control channels, with each channel configurable to 20 different functions to meet diverse application requirements. Supports DC 8V-36V wide voltage input, with anti-reverse connection protection to prevent module damage from incorrect power connections. Includes power indicator light and relay suction indicator light. Offers a minimum settable time function of 1 second, ensuring precise timing with an error of less than 1%. Incorporates an automatic power-saving function. All setting options are automatically saved, ensuring settings are retained even after power loss. Trigger signal input supports user selection for high-level or low-level pulse triggering. This 8-channel multi-functional relay control module utilizes industrial high-quality components, meticulously designed and processed for stable performance and ease of use. It's widely applicable in various power control scenarios. The module comes with pre-set functions (up to 20 types), a wide voltage power supply design (8-36V), and a linkage function for each channel, allowing users to freely combine new applications like sequential or cyclical linking.
