Provides low current switching of high-current equipment.
MiniBus saves money, weight, battery power and installation time!
The MiniBus™ consists of two small digital modules linked by dual twisted pair shielded cable.
A typical system contains the following elements, and comes with programmable software. Panel Switches, such as Cole Hersee electronic DSRocker™ switches are mounted on the panel. They connect behind the panel to the SIM, an 8-channel Switch Interface Module. The SIM unit connects via a twisted pair cable to the PDM (Power Distribution Module) which contains electronic relays that switch the target motors or lighting.
- Simplifies behind-panel harness wiring.
- Simplifies through-panel wiring.
- Improves reliability – using existing fly-by-wire technology.
- Easy diagnostics.

Traditionally, all secondary circuits on vehicles - such as lighting and powering equipment such as hoists, outriggers, winches, snowplows, tailgates, etc – have been operated from a central electrical panel. And as variety of equipment has grown, so have the number circuits and wire sizes!
MiniBus™ changes all this by replacing large and heavy cables with just one communications cable. No more heavy wires and expensive cabling bills! No more routing of complex harnesses through decks and bulkheads! And installation of auxiliary control panels is easy.
MiniBus™ provides straightforward and cost-effective control of motors or lighting, and is designed for both 12V DC and 24V DC electrical systems. It has many applications in boats and road/off-road vehicles that have ancillary motors.
A basic MiniBus™ digital switching system consists two compact modules which connect the switches on the panel to the loads. The PDM unit contains the electronic relays which operate the loads, and connects directly to the battery. The SIM unit is located near the switches (usually behind the panel). The PDM (Power Distribution Module) provides the SIM with continuous status information on each load, and the SIM (Switch Interface Module) sends real-time data to the switches.
The MiniBus™ system is scalable up to 128 discrete switching channels. It operates with Cole Hersee Sigma™ switches or any other industry-standard low current switches.
Reduced wiring complexity
Communication between the two modules is by a simple twisted pair of wires, rather than a heavy and bulky harness. MiniBus replaces conventional power distribution panels. Labor costs of installation are significantly reduced.
Solid-state Reliability
The MiniBus system has no moving parts, and therefore provides higher reliability and longer life than mechanical components.
Overcurrent Protection
The smart relays contained in the PDM provide multiple layers of overcurrent protection. Each PDM provides up to 20A per output (maximum 100A per module), and each load can be programmed for different trip currents between 2A and 20A. The PDM will disconnect the load from the battery if the trip current exceeds the programmed trip current. An overcurrent or no-load status will trigger an optional audible or visual alarm.
High Reliability Digital Switches Cole Hersee Sigma™ digital switches operate like electromechanical rocker switches, and they contain LED lighting which gives real-time indication of the status of each load. Each Sigma™ switch can be programmed to facilitate any switch function, such as momentary/maintained, or toggled/latched.
Customizable
MiniBus functions and features can be customized using the supplied applications software. Users can customize the MiniBus system to their specific requirements.
Expandable
The MiniBus™ system is scalable up to 128 discrete switching channels, utilizing 16 PDM and 8 SIM units. Users can readily add loads to a typical system, as well as additional control panels.
