Discrete I/O Modules with Relay Outputs and CAN From Axiomatic

The Discrete I/O Module reads 12 discrete inputs and sets 8 Form C relay outputs while networking with other CAN devices (SAE J1939 or CANopen®) in a machine control system. The unit is a battery powered device with the ability to withstand engine cranking, reverse polarity and transient power conditions. In engine applications, information is provided to the engine control system using single-frame J1939 or CANopen® application-specific PDU2 type messages. Outputs can be controlled by any input or CAN message. A bi-color LED indicates operational status.

The module has a number of setpoints that allow the user to configure it for their application. The Windows-based Electronic Assistant can be used to configure the module over the CAN J1939 line. The setpoints can also be saved to a file and flashed into other similar modules over the CAN bus. Alternatively, a RS-232 interface allows for quick user configuration adjustments using Windows HyperTerminal or other similar terminal software. Settings are saved to non-volatile memory upon command.

The unit features rugged packaging and watertight TE Deutsch connectors for an IP65 rating. The module is UL recognized for UL508 (FTPM2) – Controls for Stationary Engine Driven Assemblies and has a cUL recognition as well. The control carries a CE mark for the EMC and RoHS Directives. The DIO Module meets the environmental, EMC and vibration requirements of generator set applications in marine installations and, depending on the model, may have type approvals from several marine societies (LR, DNV-GL, ABS, RINA, CCS, and BV).

Model AX031800 is a new alternative to AXDIO128 or AXDIO128-03 and AX031850 features the same functionality in a compact enclosure.
