S800 front view image

The introduction of the Series 800 controller marks a renewed dedication to our customers. The Series 800 is an all-purpose engine controller, designed to meet the needs of nearly every municipality. The controller is designed to be a municipal-specific control platform, and incorporates the necessary hardware to efficiently execute these projects.


All-Around Simplicity

The Series 800 control platform embodies the culmination of the experience we have gained over nearly 60 years in the control business. We enhanced the standard features, lowered the cost, increased the connectivity options, and increased the configurability by basing the controller on Linux, an open-source operating system.

The Series 800 benefits from a simplified modular design. We've reduced installation and maintenance costs, while greatly increasing the quality and reliability of the product. The Series 800's single board design eliminates the majority of inter-panel wiring that is traditionally seen with PLC control panels, while retaining features such as true hardware interlocks for local and remote E-Stops.

The Series 800 has the ability to withstand a wide ambient temperature range, comes standard in a NEMA 4X rated enclosure and has an HMI display that is viewable in extreme environments.

We Can Help You Exceed Emissions Standards
Many municipalities have an additional challenge outside of engine controls. An increasing number must meet or exceed a variety of engine emissions standards. Meeting these standards can be achieved by adding a plug-n-play FW Murphy Air Fuel Ratio controller to the enclosure. AFR information is directly displayed on the existing Series 800 HMI display.

Additionally, a Johnson Matthey emissions control solution including housing and elements may be required, based upon your emissions requirements.

Remote Monitoring Capability


The Series 800 control platform is designed to allow enhanced remote visibility into the operation of the controlled engine or electric motor driven pump.


Gaining remote insight into the operation of your your equipment gives peace of mind that everything is operating at peak performance. This is especially critical during a storm event or other high demand situation. If equipment malfunctions, the system is designed to alert your critical operations personnel for quicker dispatch to the site, and provide insight on what to expect when they arrive. This helps reduce downtime and improve the efficiency of both the site operations and the overall team of operators. Improving the cutting-edge technology that allows our customers to view this information on their remote laptop or smartphone is a very important goal for our engineering team.

Security is our number one priority.


By partnering with best in class web services providers, we can leverage the technology used by companies like Netflix and Amazon to make sure your equipment is safe from outside intruders. The architecture is designed to allow for data to be sent from the Series 800 controller. No commands from the outside can be used to modify the operation of the controller. Control logic and set points are restricted to local, physical access. This architecture allows for text message alerts, data logging of equipment operation and station variables, trend data, and other data that can be used to predict equipment problems before they happen.


The Series 800 Municipal Engine Controller with remote monitoring capability will benefit station operators immensely by allowing them to:


•   Monitor their engines from any internet-enabled location, whether it’s across town or worldwide.

•   Use a secure one-way communication infrastructure out to the cloud.

•   Data log storm event information for future analysis.

•   Have peace of mind that their engines are working correctly during a storm event or power outage.

•   Perform any of the above functions from their smartphone, laptop or any other capable device.
