Product Description

The H7E-RA-B Automotive Relay Module is a compact, high-performance component designed for automotive electronic systems such as powertrain control and body electronics. It features 4 low-voltage input channels and 6 high-current SPDT relay outputs (30A/14VDC) with normally open (NO) contacts, supporting direct integration with multiple vehicle control modules. The device operates within a 9-36VDC range and withstands temperatures from -40°C to +125°C, ensuring reliability under harsh conditions. It includes LIN/CAN communication interfaces for seamless network connectivity. Key advantages include IP67-rated rugged housing, EMI resistance, and plug-and-play installation via a 12-pin connector. Notable limitations include no built-in diagnostics or adjustable timing. Dimensions measure 45mm x 30mm x 20mm. Parameters like battery capacity, screen size, and detection distance are N/A for this relay module. Detailed specifications are available in the H7E-RA-B Datasheet for automotive engineering applications demanding robust switching solutions.
