EMIT Dynamic Control is a modular solution engineered to meet the wide range of requirements found in air fuel ratio control, engine ignition, compliance monitoring, and compressor protection and control applications. The architecture of the system is based on a single user interface that is capable of operating and managing multiple modules, each with their own primary function. This configuration allows the system to be highly flexible in the approach necessary to solving issues found in typical and complex applications. Additionally, each module is capable of accepting a range of auxiliary inputs that can be used to further facilitate advanced operations for the most demanding scenarios.

The system is built around the Dynamic Control Touchscreen, which provides a 12” touchscreen display to present data and interact with any connected modules. Modules are connected to the touchscreen through a high-speed daisy-chain style configuration, and upon detection are automatically made available for operation within the display. The display also acts as the communication hub for the system providing access to datalog downloads through USB, remote data access through Ethernet and RS-485 connections, local WiFi Access, and cellular remote data access.

Touchscreen Connections


The connections available on the back of the touchscreen are shown in the diagram above, and include the following:

  • SYSTEM: Main power and communications connector. Input voltage is 12-30v DC and should be fused to 2A
  • MODBUS 1,2: Modbus ports for connection to SCADA system (RS-485). Can be configured for different baud rates.
  • ECU CAN, CDL, ECU RS-485: Connection options to ECUs (Engine control units)
  • ETHERNET: Ethernet port for Modbus/TCP
  • USB A: USB Host port for downloading datalogs and other items to a thumb drive
  • USB B: Manufacturing use only
  • CELL 1,2: Connections for cell phone antenna(s) for remote data collection if activated. Cell 2 is only used in rare cases where signal strength is very low.
  • WIFI 1,2: Connections to wifi antenna(s) for local viewing of runtime data on a cell phone
  • GPS: Connection to GPS antenna

NOTE: The back connections should be protected from access in the panel by some tool-required latch.
