Stinger SPXSH440 SwitchHUB 4 Channel Solid State Relay

Stinger SPXSH440 SwitchHUB 4-Channel 100A Solid State Relay Block

Replace up to four mechanical relays with one clean, silent, IPX6-rated solid state relay block 100A total continuous output, thermal and short circuit protection per channel, and direct integration with the Stinger SPXM1 powersports media centre.

Product Overview

The Stinger SPXSH440 SwitchHUB is a 4-channel solid state relay block designed to replace conventional mechanical relays in powersports, marine, and off-road vehicle installations. It delivers 100A of total continuous output across four independent channels (1x 40A and 3x 20A), with each channel individually controllable via positive or negative low-current trigger inputs.

Unlike mechanical relays, solid state relays operate silently and produce minimal electrical interference. Each channel includes thermal overload and short circuit protection, with built-in LED indicators for at-a-glance status monitoring of active/inactive states and protection events.

The SPXSH440 is designed for direct integration with the Stinger SPXM1 powersports media centre, allowing remote control of connected devices from the head unit itself.

Please note: Each channel accepts either a negative or positive trigger input both cannot be used simultaneously on the same channel.

Frequently Asked Questions

What is the advantage of a solid state relay over a mechanical relay?

Solid state relays have no moving parts, which means they operate silently and produce significantly less electrical interference than conventional mechanical relays. They are also more reliable over time as there are no contacts to wear out or corrode — particularly important in marine and off-road environments.

Can I use both positive and negative triggers on the same channel simultaneously?

No. Each channel accepts either a positive or a negative trigger input — both cannot be active on the same channel at the same time. Choose the trigger type that suits your installation for each channel independently.

What does IPX6 mean for this relay block?

IPX6 means the SPXSH440 is protected against powerful water jets from any direction. This makes it suitable for marine, powersports, and off-road installations where exposure to water spray, rain, and splash is expected. It is not rated for full submersion.

Does this relay block work with head units other than the SPXM1?

Yes. The SPXSH440 can be triggered by any 12V low-current positive or negative signal, making it compatible with a wide range of switches, head units, and control systems beyond the SPXM1. The SPXM1 integration allows for direct remote control from the head unit itself.

How many total amps can the SPXSH440 handle continuously?

The SPXSH440 provides 100A of total continuous output across all four channels — 40A on output 1 and 20A on each of outputs 2, 3, and 4.
