Why Choose the Unitronics UAC‑CB‑01CAN Uni‑COM™ CB CANbus Module?
The Unitronics UAC‑CB‑01CAN is a DIN‑rail mounted communication expansion module that adds a galvanically isolated CANbus port to compatible UniStream™ PLCs via the Uni‑COM™ CB connector. It enables integration with CANopen or DeviceNet® networks without requiring additional power—ideal for distributed I/O or remote telemetry using Remote Expansion Adapter EX‑RC1.
Technical Specifications
- Model: UAC‑CB‑01CAN – Uni‑COM™ CB CANbus module
- Port: Single isolated CANbus port; internally powered—no external supply required.
- Isolation: 500 VAC between port and I/O bus for 1 minute.
- Cable: DeviceNet® or CAT‑5e shielded twisted pair
- Termination: DIP switches set to ON ON by default (terminated); OFF OFF for non‑terminated units
- Operating Environment: IP20 / NEMA 1 enclosure; ambient −20 °C to +55 °C; storage −30 °C to +70 °C; 5 %–95 % RH non‑condensing
- Physical: DIN‑rail mountable (approx. 120 mm wide); weight ~100–110 g
- Indicators: Green LEDs for Tx/Rx communication activity
Typical Applications
- Connecting UniStream controllers to CANopen or DeviceNet® networks for remote I/O or sensor integration
- Serving as the backbone for up to 64 EX‑RC1 remote I/O adapters or CAN-enabled units via Uni‑COM™ CB expansion
- Supporting distributed automation, motion control or fieldbus monitoring over CANbus
Installation & Wiring Notes
- Ensure controller power is off before installing/removing modules
- Mount onto DIN‑rail adjacent to the host controller and connect the COM module plug into the Uni‑COM™ CB jack
- If it's the final module in a row, leave the COM jack cover on the next module or host to protect against ESD or debris
- Use CANbus-standard wiring: shielded twisted pair, appropriate termination resistors at both ends, and stub lengths ≤ 2 m per node
Frequently Asked Questions
- Which controllers support the UAC‑CB‑01CAN?
- Is termination switch-set by default?
- How is the module powered?
- Can I mix with other CB modules?
It is compatible with UniStream™ Built‑in models featuring a Uni‑COM™ CB connector (e.g. US5‑B5, US7‑C5/B5, US10‑B10, etc.).
Yes—the DIP switches are shipped ON‑ON (termination enabled). Switch to OFF‑OFF if the module is not at the end of the CANbus chain.
The CANbus port is internally powered and does not require external supply.
Yes—you may chain RS‑232, RS‑485 or CANbus modules as long as the CANbus module is adjacent to the host or plug; COM jacks on unused modules must remain covered.
