FuelTech's EGT-4 CAN is a 4-channel signal conditioner with CAN bus communication for use with PowerFT ECU's including the FT450, FT550, FT550LITE, and FT600. When paired with a PowerFT ECU, the EGT-4 acts as an input expander, removing up to 4 type K thermocouple inputs (grounded junction or not), such as EGT's, CHT's, oil, air, water, or other temperatures from the white ECU input channels by allowing them to communicate via the CAN bus network. Up to 4 EGT-4 modules may be used in the same installation, making up to 16 input channels available for additional data acquisition.
