FuelTech's EGT-4 CAN is a 4-channel EGT controller CAN module, connecting up to 4 type K thermocouples and sending the input signals to the ECU via CAN bus communication. Compatible with FuelTech ECU's including the FT450, FT550, FT550LITE, FT600, FT700, and FT700PLUS.In addition to acting as a 4-channel type K thermocouple CAN module, 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.
