Product Overview

The Bachmann DIO264-C operates as a high-density, standalone CAN slave module designed for distributed control architectures. This versatile unit provides up to 64 configurable digital channels, allowing engineers to tailor the input/output ratio to specific machine requirements without hardware swaps. By connecting directly to the CAN bus via dual D-Sub ports, the DIO264-C eliminates the need for expensive backplanes and complex rack assemblies. We supply this module as 100% Brand New original hardware, ensuring seamless integration into your Bachmann or third-party CANopen networks.

Technical Specifications

The DIO264-C combines extreme channel density with robust electrical protection to maintain signal integrity in high-interference environments.

Engineering Advantages

The DIO264-C resolves the challenges of high-point-count remote sensing by offering a decentralized, backplane-free solution.

• Maximum Configuration Flexibility: Unlike fixed-ratio modules, the DIO264-C allows you to define channels as inputs or outputs. This adaptability reduces spare part inventory, as a single DIO264-C unit can replace multiple variations of lower-density fixed modules.

• Stand-Alone Network Integration: The module functions as a complete CAN node. By removing the requirement for a local CPU or backplane, it reduces the physical footprint in remote junction boxes and lowers the overall system cost per I/O point.

• Superior Output Current Handling: Each output channel delivers up to 1 A of continuous current. This capability allows the module to drive heavy-duty solenoids, hydraulic valves, and large contactors directly, bypassing the need for interposing relays in many applications.

• Redundant Loop-Through Connectivity: The dual 9-pin D-Sub ports facilitate easy "daisy-chain" wiring. This simplifies the CAN bus trunk layout and ensures that the communication signal remains stable across the entire network branch.

• Galvanic Signal Integrity: 500V galvanic isolation protects the internal control logic from field-side electrical noise and ground loops. This protection ensures reliable data transmission even when the module sits adjacent to high-frequency variable speed drives (VFDs).

FAQs

• Does the DIO264-C require a separate bus terminator?

  Yes. While the module supports loop-through, you must install an external 123 $\Omega$ termination resistor at the physical end of the CAN bus segment to prevent signal reflections.

• Can I use this module with non-Bachmann controllers?

  Yes. The DIO264-C follows standard CAN communication protocols (Node ID range 1–254), making it compatible with any industrial PLC or PC-based controller that supports CANopen or standard CAN frames.

• What is the maximum output switching frequency?

  The module supports switching frequencies up to 500 Hz. This high-speed performance makes it suitable for pulse-width modulation (PWM) tasks and rapid-cycle packaging machinery.

• Is there a lower-density version of this module?

  For applications requiring fewer points, Bachmann offers the DIO16-C (16 channels) and DIO32-C (32 channels), both of which share the same standalone CAN slave architecture.
