Axiomatic Technologies offers a range of CAN I/O Modules with Form C Relay Outputs for diesel and marine engines, gensets, and machine control systems. Many of these units come in rugged enclosures of various forms and sizes which are suitable for use in harsh environments. Modules in compact and DIN Rail enclosures are also available. All these modules feature isolated CAN ports.

The users can use the Windows-based Axiomatic Electronic Assistant to configure the I/O modules over CAN for their applications. The setpoints can also be saved to files and flashed into other modules of the same part number over CAN bus. Settings are saved to non-volatile memory upon command. The DIN Rail units AX031950, AX031950-01, and AX031950-02 also feature NFC communication. They can be configured conveniently via Axiomatic’s E-Write NFC Application which is available for a fee from Apple App Store for iOS devices and Google Play Store for Android devices like smartphones and tablets.

The AX180800 can read 20 thermocouple, 2 PT 100 RTD, and 4 universal signal inputs and can control 6 Form C relays. It can communicate over an Ethernet (TCP/IP) port as well as 2 isolated CAN ports. It uses SAE J1939 protocol with auto-baud-rate detection.

The models AX031800, AX031801, AX031850, AX031850-01, AX031850-02, and AX031851 can read 12 discrete inputs and operate 8 Form C relays. They can network with CAN SAE J1939 or CANopen® fieldbus based on the part number. A bicolor (red and green) LED in AX031800 and AX031801 shows the device’s state.

DIN Rail mount units AX031950, AX031950-01, and AX031950-02 boast 1 universal input, 1 Form C relay output, 1 analog output, and a +5V reference. The state of the device is shown through a bicolor (red and green) LED indicator.

A few modules like AX130750, AX130751, AX130770, AX130770-01, AX130770-02, and AX130771 do not feature any inputs but provide 1 Form C relay and 2 analog/digital outputs. They support either CAN SAE J1939 or CANopen® networks depending on the model.

The CAN I/O Modules with Relay Outputs can work at nominal battery voltage of 12 or 24 Vdc. The voltage operating ranges of the devices are much wider. Electrical protections like reverse polarity, under and over-voltage, and transient and surge protection are provided. Details may vary in individual models. Please see their respective datasheets for details.

A brief comparison of these I/O modules is presented below.
