EIM image

The EMIT Interface Module (EIM) is an 8” touchscreen display and communications hub for interacting with all  EMIT control modules. On screen, data is presented in a variety of forms that allow for system diagnostics, technical troubleshooting, and module interaction. Available communications include MODBUS RTU for remote monitoring, USB for datalog access, and CAN for EMIT ETS modules.

  • “Notes” feature provides on-site note taking and data storage using on-screen keyboard
  • Alarm “Snapshot” feature shows system status during and up to one minute before an alarm is triggered
  • Three levels to security access to restrict adjustments to authorized users
  • Datalogging present for all system inputs – no setup required
  • Historical graphing of any input for troubleshooting and diagnostics
  • On screen help and troubleshooting for all EMIT modules


The EMIT Annunciator module is a highly configurable alarm and condition monitoring device that is designed to protect engine and compressor equipment from damage as well as personnel from harm. The Annunciator uses a variety of analog, switch, and thermocouple inputs and digital and analog outputs to perform a range of controlled operations as well as safety condition monitoring. Operations include: Auto Start, pre-alarm warnings, controlled shutdowns, custom application PID loop control, pre-/post-lube control, and no flow monitoring.

  • High input and output count
  • Inputs: (30) switches, (1) magnetic pickup, (12) analog, (20) thermocouples
  • Outputs: (6) transistorized digital outputs, (2) Form-c (SPDT) relays, (2) analog outputs, (1) fuel valve control, (1) G-lead shutdown, (1) digital shutdown
  • Input statistics for diagnosing recurring and problematic issues
  • Input and process on-screen graphing
  • Simple input alarm classes: A, B, C, ESD, and ‘No Action’ class configurations
  • Auto Start and controlled shut downs
  • Shutdown history system snapshot functionality
  • Interfaces with the EIM 8” display for MODBUS access, data graphing, data logging, and diagnostic information

Ignition Control


The EMIT Ignition Controller Module (ICM) is an electronically controlled ignition system that features highly accurate and reliable spark control and monitoring capabilities through the use of transistorized inductive technology. The ICM is available in two offerings: an ICM8 for engines with up to eight cylinders and an ICM16 for engines with up to 16 cylinders. Both the 8-cylinder and 16-cylinder ignition modules offer the same feature set and are appropriate for rich-burn or lean-burn combustion and naturally-aspirated or turbo-charged engines fueled by natural gas.

  • Transistorized inductive ignition produced significantly longer spark duration than capacitive resulting in improved combustion and improved misfire performance
  • Timing automatically adjusts based on changes to speed and load
  • Engine position is derived from auxiliary drive – no hall sensors or magnetic pickups required
  • Diagnostic information based on spark duration, coil energy demand, misfire performance
  • Individual cylinder timing available
  • Overspeed and underspeed engine protection
  • Interfaces with the EIM 8” display for MODBUS access, data graphing, data logging, and diagnostic information

Speed Control

Speed Control Image

The EMIT Governor is an electronic speed control system for stationary carbureted natural gas engines. It functions by controlling an electronic throttle body installed to the intake manifold of the engine. The desired speed of the engine is set by a three-position switch installed into the instrumentation panel. It can be set for idle RPM, manual RPM control, or automatic RPM control based on the application. Optionally, a suction pressure or discharge pressure sensor can be used to adjust RPM to changes to compressor suction or discharge pressures.

  • Instrumentation panel switches for manually controlling engine speed and engaging automatic control
  • Fast transient response to changing load conditions
  • Optionally controls RPM to changes in suction or discharge pressure resulting in fuel savings and reduced component wear
  • Adjustable idle speed, speed ramp, cranking throttle position, and control gains
  • Overspeed and underspeed shutdown protection
  • Interfaces with the EIM 8” display for MODBUS access, data graphing, data logging, and diagnostic information

Air/Fuel Ratio Control

AFRC_image (Small)

The EMIT AFRC module is designed to control the air/fuel ratio of carbureted turbo or naturally aspirated stationary natural gas engines for either rich-burn or lean-burn applications. Control is accomplished using EMIT’s patented AutoControl algorithm which automatically controls the fuel valve based on catalyst operation and performance. When controlling with AutoControl, no user setpoint adjustment is required and control will adjust to environmental changes including load and ambient conditions.

  • Single bank, dual bank, rich burn, and lean burn operation
  • Patented AutoControl control algorithm for rich-burn configurations
  • Protective shutdowns to protect catalyst and engine components
  • Adjustable load delay allows engine and compressor to load before taking control
  • Advanced PID control allows valve to find targets quickly with reduced overshoot
  • Interfaces with the EIM 8” display for MODBUS access, data graphing, data logging, and diagnostic information
