DynaGen TG350 Genset Controller

  • SKU # TG350
  • $325.00

Step up to the New DynaGen TG410 and enjoy some great new features added to the TG350.  DynaGen made it possible to monitor and display current with optional current transformers.   The TG410 also has electronic engine support for standard J1939 Engines (Tier II, III & IV) and a few more you can read about below.


For engines or generators

The TOUGH series controllers are designed to provide complete control, protection and engine instrumentation for both standard and electronic canbus engines, as well as 3-phase volts/amps metering or generator applications. The module is easily configured as either an engine controller or a generator controller using either the front panel buttons or our PC Configurator software. TOUGH series controllers are ideally suited for severe duty applications where reliability is critical such as mobile and stationary engine equipment and generators.

Displays (meets NFPA-110 Level 1):


  • Oil Pressure
  • Engine Temperature
  • Fuel Level
  • Oil Level
  • Hour Meter
  • RPM
  • Real time clock display with time/date
  • Battery Voltage
  • J1939 DTC codes with custom text
  • Two customer defined parameters (temperature, pressure, voltage, levels)
  • DPF and DEF status icons
  • 3-Phase AC Volts, Amps and Hz (for generators)

Snap-on RelayPak Option

The RelayPak is socketed to accept four industry standard cube relays. When installed, the RelayPak (RP-100*) eliminates the need to mount and wire external slave relays for Fuel, Crank, and up to two other loads.

* RP-100 includes mounting pack and 3X40 A (resistive) UL pilot duty rated relays
