Thermocouple CAN controller connects to J1939 control system

Axiomatic (CA) has introduced the TC (Thermocouple) and Analog Signal Inputs to CAN Controller. It is an I/O controller for marine engine and power generator set control systems and features J1939.

THE CONTROLLER RECEIVES INPUTS from engine coolant, fuel and differential pressure sensors, engine temperature sensors, thermistors, as well as thermocouples and is networked to a J1939 based control system. Seven +5-V references (10 mA) are provided to power the sensors. The two CAN ports are isolated from signal inputs and thermocouple inputs. Using the Electronic Assistant programming tool, the user can select the desired inputs from the following signal options: four thermocouples (Type J, K or T), seven analog voltage signals (0 V to 5 V, 0 V to 10 V) and three analog signal inputs (0 V to 5 V, thermistor).

A rugged power supply interface accepts 12 VDC, 24 VDC or 48 VDC nominal for battery powered machine applications. The unit carries an IP67 rating. The rugged enclosure with four 12-pin-IPD connectors is suitable for diesel engine environments. It operates from -40 °C to +85 °C. Simulink block libraries allow OEM designers to program the device for specific applications. Application fields are for example power set engine control systems, oil and gas equipment automation, marine engine applications and off-highway machine automation.
