Fiber Optic/CAN, RTD Isolator Module, SAE J1939
Item # AX143030 — Fiber Optic/CAN, RTD Isolator Module, SAE J1939
AX143030 is an FO to CAN, RTD Isolator designed to work as a system with the AX180610 RTD to FO Module. The modules work together as a pair over a fiber optic (FO) connection. The split functionality of AX180610 and AX143030 helps remove the RTD controller module from the field to an area where it can be better protected as it is prone to damage and tampering in the field. Communication over FO provides low latency and inherent isolation between the modules. AX143030 features isolation between CAN and FO. All RTD channels are automatically sent over the FO when the devices are powered on, without additional programming or configuration. The RTD-FO module relays temperature data to AX143030 over an FO connection. The FO-CAN module remotely processes this data and provides temperature readings and related warnings through an SAE J1939 CAN bus to the engine control system (ECM) at 250 kbit/s. The user can program a set of parameters for each input to support diagnostic messaging for RTD integrity and fault notification as well as use Averaging Blocks to provide grouping and filtering options for the inputs. AX143030 is configurable via CAN bus using the Axiomatic Electronic Assistant KIT (sold separately). Setpoint configuration can be saved in a file which can then be utilized to apply the same configuration to other AX186010 and AX143030 pairs.
