Class I, Division 2 HMIs

Maple Systems offers Class I, Div 2 certified HMIs designed to keep operators and their environment safe. Our CID2 HMIs are being used in a potentially dangerous environment or around flammable hazards everyday, and are designed to prevent dangerous explosions and ensure worker safety. These products are used in industries including oil and gas, mining, painting, chemical processing, pharmaceutical, food processing, and more.

With Built-in drivers for ABB Totalflow, Emerson ROC 800, SCADAPack, and Emerson ControlWave, our Free EBPro Programming Software makes it easy to integrate our C1D2 HMIs into your Tank Battery, Lact Skid, or SWD control panel, with no extra costs or fees.

Application Stories

LACT Skid – Custody Transfer

An Integrator in Pecos, TX uses our C1D2 HMIs on their Lease Automatic Custody Transfer (LACT) Skids to sample and measure oil so it can be properly and accurately delivered from the well site to the customer. Our HMI is used to display information regarding the transfer process as well as alert operators and stakeholders of operational issues, such as high water and sediment content. Fail-Safe shutdown and gas detection procedures are also built into the HMI as well as Cloud transmission for remote access.

Remote Access

A Value Added Reseller in Midland, TX created a remote access kit for their end users to save time and cost on deploying technicians to remote locations for troubleshooting and clearing alarms on their skids/pump jacks. This kit included our cMT-SVRX-822, power supply, and a broadband cellular router mounted just outside the C1D2 area, using a C1D2 ethernet cable connected to the PLC within the C1D2 area. With EasyAccess 2.0 preinstalled and activated on our cMT-SVRX-822, his customers could log in from home and view the event log and alarm history, clear all alarms and adjust the program preventing future failures.

Waste Water Treatment Plant

An Integrator in Roswell, NM was brought into a large Wastewater Treatment Plant after their SCADA system went down. They had no way to view or troubleshoot alarms. He installed 7 HMIs at key stations throughout the plant, and one of our Headless cMT-SVRX units in the centrally located control cabinet. Alarm and Event data gathered from each of the 7 locations is now being sent to the cMT-SVRX.  With the use of our EasyAccess2.0 and cMT Viewer, Plant Managers and workers can log in locally as well as remotely to view and clear any alarm data, monitor tank levels, flow and pH, and adjust as needed, without leaving their chair.

Tank Batteries

An Integrator in Roswell, NM uses one of our C1D2 HMIs as the eyes into their 5 Tank Batteries. It’s used to view tank levels, control oil flow in and out of the tank, as well as control gas injection at the pumps. Each tank has its own recipe for injection, based on the flow rate, the HMI tells an actuator how much gas is allowed to be pumped into each well, improving the flow of oil into the tanks.

Injection Well Control

An OEM in the Permian Basin uses our 7″ C1D2 HMI to control and monitor the operations of Injection Wells used for disposal of wastewater produced during oil and gas extraction. Our HMI gives the operators an interface to view flow rate, injection volume, and pressure and allows for them to easily make adjustments for efficiency and safety making sure the fluids remain contained, protecting nearby aquafers and there are no unexpected pressure surges.

Meter Run

An OEM in Odessa, TX needed a low cost HMI that could communicate to his Emerson ROC800 and view Static Pressure, Differential Pressure, Temperate and Flow values on their Meter Runs. With our free, EBPro Programming software, the Emerson drivers are already built in so our 7″ C1D2 HMI was the perfect solution.

pH & ORP Sensors – Measurement

An OEM in Orange, CA uses our 7″ C1D2 HMIs on their HiQDT Smart Digital Sensors for measurement of pH, ORP and Dissolved Oxygen parameters at hazardous locations. Smart Digital MODBUS RTU pH, ORP, Dissolved Oxygen, Ion Selective and Conductivity sensors can be connected to any PLC that can act as the MODBUS RTU Master. No local transmitter required (direct to PLC or SCADA) since the HMI is mounted at the installation site. Remote access for troubleshooting and maintenance was a must for cost and time efficiencies making our C1D2 HMI the only choice for his touchscreen controllers.

Supervisory Control and Data Acquisition (SCADA)

Early on, these types of systems were built using proprietary hardware and software, operating in isolation without connections to other networks. Operators had to reside in a centralized control room or command center because human-machine interfaces. (HMIs) did not support remote access. Any information provided to personnel other than operators was delivered via reports, which often had a significant time lag. Once devices were connected to much larger networks, they became more complex and gained broad capabilities.

Why Class 1, Division 2

We offer many Class I, Div 2 certified solutions designed to keep operators and their environment safe. These products are used in industries including oil and gas, mining, painting, chemical processing, pharmaceutical, food processing, and more. C1D2 is an important factor to consider when looking for an HMI solution to use in hazardous industries.

A Class I, Division 2 location is:

  • A location in which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment.*
  • A location in which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment.*
  • A location that is adjacent to a Class I, Division 1 location, and to which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors above their flash points might occasionally be communicated unless such communication is prevented by adequate positive-pressure ventilation from a source of clean air and effective safeguards against ventilation failure are provided.*
