Acromag has released new isolated CAN bus modules to interface network sensors and actuators to high-performance control systems. Two versions of the CAN bus interface module are available. The IP560 is an Industry Pack ANSI/VITA-4 card that plugs into VME, CompactPCI, and PCI bus mezzanine carrier cards or single-board computers in embedded systems. IOS-560 models are designed for use within Acromag's I/O Server industrial PC, a small fanless box computer, which services mobile computing, machine control, and test applications. Both CAN bus interface modules feature two channels with optional isolation. Each channel has an NXP SJA1000 CAN controller with a TJA1041 transceiver. Extended temperature models support -40 to 85 degree C operation.
"The addition of CAN bus interface modules to Acromag's line of I/O products provides even more flexibility to control system developers who can mix several I/O functions on a single carrier card for high-density, cost-effective computing solutions," states Joseph Primeau, Sales and Marketing Director - Embedded Products.
All models have two complete CAN bus interfaces, each using an NXP SJA1000 CAN controller with a high-speed TJA1041 transceiver. The advantage of this design is that it allows reporting of bus fault conditions directly from the transceivers. It also has the ability to transmit, receive and perform message filtering on extended and standard messages. The modules support CAN 2.0B protocol compatibility and ISO 11898 compliance for Part A (11-bit) and Part B extended (29-bit) arbitration IDs. PeliCAN mode extensions provide numerous communication capabilities.
An isolation option eliminates ground loop potentials and protects equipment from electrical noise, surges, and spikes. The 1000V isolation barrier safely separates channel-to-channel and channel-to-host.
