How Maple Systems Customers are using our Class I, Division 2 Products

A Controls Engineer in Erie, PA selected our CID2 HMI to manage Plant Nursery Irrigation Systems, control pump VFDs, PID loops and monitor pressure/PH levels.
A Systems Integrator in Michigan has been using Maple Systems HMI5070L model HMIs for years in various process control applications and reports that end-users find them to be reliable and easy to operate.
An OEM in NEw Jersey incorporates the HMI5070L into their CID2 Specialty Gas Handling Systems.
An OEM in Missouri uses the HMI5070LB as the interface for their precision Commercial Food Ovens.
An OEM in Wisconsin uses the HMI5070L to oversee multiple Allen-Bradley Micrologix 1400 PLCs in their Water Softening, Filtration, and Ion Exchange Systems.
Engineers at an OEM in Ohio chose a Maple unit to allow operators of their Dancer Tension Control Systems to select setpoints, monitor, and collect data from an integrated Modbus TCP/IP Slave controller.
In Connecticut, a Maple Systems OEM customer uses our products to control their high-performance Ultrasonic Metal Welding Machines. The HMI interfaces with a Galil DMC motion controller, performs data collection, and allows for on-demand, inline job-switching using our Enhanced Recipes feature.

What makes a Class I, Division 2 Location?

If the location of your HMI installation fits the below criteria, take a look at our Class I, Division 2 options.

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.*

PLCs

Maple's complete line-up of low-cost Programmable Logic Controllers (PLCs) with built-in I/O and expandable I/O options. These powerful units are fully functional PLCs with digital and analog I/O that support high-speed counters and PWM (pulse width modulation). Analog I/O options support several voltage and current modes as well as RTD (resistance temperature detection) and thermocouple sensors to measure temperature. And they are all Class I, Division 2.

Alphanumeric OITs

Our OITs are powerful, affordable operator interface terminals. These units offer best-in-class features including 2 and 4-line LCD and VFD Displays,16 and 24-key keypads, unique user-definable keypads, and slide-in legends. All our OITs operate in temperature extremes ranging from -10˚C up to 65˚C and meets strict Class 1, Division 2 requirements. Made with a rugged aluminum enclosure in the USA, our LCD and VFD OITs are ideal for harsh environments.
