Innovate TC-4 4 Channel Thermocouple Interface – 3784



Out of stock


The Innovate TC-4 is a 4 channel thermocouple interface. It’s perfect for determining your fuel distribution where running a collection of wideband sensors could be prohibitively expensive. Works with type K thermocouples, sold separately. You can log the data to a PC running LogWorks, Pocket Logger, or a DL32 data logger.

Each of the four inputs of the TC-4 can be configured by the user for either EGT range (32-1999 deg F, 0-1093 deg C) or for CHT range to measure cylinder head temperatures (32-572 deg F, 0-300 deg C). The TC-4 can also be used to measure other temperature metrics such as turbo inlet and outlet temp, catalytic converter temp, transmission temp, and more.

The TC-4 is also a key component of Innovate Motorsports’ Modular Tuning System (MTS). Using the TC-4’s serial ports you can daisy-chain other Innovate devices such as the XD-16, AuxBox (LMA-3), LC-1, DL-32, and SSI-4. Includes PC interface cable, a cable for daisy chaining to other MTS devices, and a CD with Innovate’s LogWorks software.
