The Temperature Scanner monitors up to 20 thermocouples and 2 RTD’s to provide the temperature information to the engine control system over SAE J1939 CAN bus. The channels are independently configurable as Type J, K, B, E, N, R, S or T thermocouples. Temperature information can include exhaust temperature, winding 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. There are 4 universal signal command inputs. The control sets 6 Form C relay outputs. Integral diagnostics determine thermocouple integrity. All inputs are fully isolated from the CAN lines, and from the power supply. The two CAN channels are fully isolated from one another in the hardware which allows for different CAN networks to be connected. In the software, each will also act independently where incoming or outgoing messages can be configured to receive or send on a specific CAN channel. Modbus TCP/IP communications are also available. The scanner is enclosed in a rugged IP67 rated enclosure with an 86 pin TE Deutsch connector.
