The Thermocouple Scanner monitors up to 20 thermocouples and provides the temperature information to the engine control system over SAE J1939 CAN 2.0B bus. The controller has 250 kbps baud-rate for the CAN communication. It interfaces with ComAp controllers (It can be used in place of the discontinued CA171000. See user manual UMAX185000-10 for details.). The input channels are independently configurable as Type J, K, B, E, N, R, S, or T thermocouples. Temperature information can include exhaust temperature and fluid temperature monitoring. All 20 channels of temperature data are automatically sent over the CAN bus when power is applied with no additional programming or configuration required. Integral diagnostics determine thermocouple integrity. All inputs are fully isolated from the CAN line, and from the power supply. During set-up, using a USB-CAN converter and a PC, the operator can configure the controller via the Axiomatic Electronic Assistant to suit a wide variety of applications. Settings are saved to non-volatile memory upon command. The Thermocouple Scanner features rugged packaging and connectors, which are TE Deutsch equivalents, for an IP67 rating. Applications include control systems for industrial and marine power generator sets (stationary or portable).
