Description

Need to power multiple solenoids with high-speed switching but without the cost of multiple solid-state relays? The HSD-4 High Side Driver module is designed to control up to four medium-current 12V devices using solid-state switching, perfect for solenoids that require rapid operation.

Features:

  • Four High-Side Drivers: Ideal for solenoids that need 12V power instead of ground
  • Compatible with MS3Pro, MicroSquirt, or MegaSquirt: Ground-triggered outputs can easily connect to the HSD-4’s inputs
  • Handles up to 8 amps per channel: Reliable performance for medium current solenoids
  • Epoxy potted: Maximum vibration and water resistance, suitable for underhood use

Applications Include:

  • Toyota A340/A341 transmissions
  • Subaru W4A33 transaxles
  • BMW Double VANOS variable valve timing solenoids
  • Other solenoid setups needing rapid switching and 12V power

The HSD-4 module is perfect for situations where the solenoid ground is tied to the body, and only a single 12V wire powers the solenoid. Designed for fast, precise control in demanding environments.

Specifications:

  • Operating Voltage: 12V DC
  • Maximum Current: 8 Amps per channel
  • Number of Channels: 4 High-Side Drivers
  • Trigger Type: Ground-triggered
  • Switching Frequency: Suitable for rapid switching solenoids
  • Module Construction: Epoxy potted for durability and environmental resistance

Included in Box:

  • HSD-4 High Side Driver Module

Where is this product manufactured?

  • The HSD-4 high side driver is proudly manufactured in Gainesville, Georgia, USA.

How does this wire up to my ECU?

Is it possible to use the HSD-4 high side driver module with a brand [enter your brand here] ECU?

  • Probably. Most ground switched outputs will activate the HSD-4.

Can I use the HSD-4 high side driver with nitrous solenoids?

  • Check the coil resistance before wiring this to a nitrous solenoid, as the HSD-4 will not supply more than 8 amps per channel. We do not recommend using the HSD-4 with a solenoid if the coil resistance is under 2 ohms.

Can I trigger two or more outputs with a single input?

  • Yes, you can wire multiple input wires to a single ground triggered output on your ECU if you want the HSD-4 to activate several devices at once.
