FR-2054T
8-channel FRNet Isolated Digital Input and 8-channel Isolated Digital Output Module.

The FR-2054T module provides 8 Isolated Sink Type Digital Outputs and 8 Isolated Sink/Source
Digital Inputs. The I/O data transmission is controlled by the FRnet control chip developed by
ICPDAS. FRnet was designed to provide deterministic high speed network communication. The
communication mechanism is dominated by the token-stream, which is generated by the network
manager located at a specific node (SA0). This manager provides for fixed scan-time and I/O
synchronization capabilities without the need of any special communication protocol.
Special anti-noise circuitry has also been built into the FRnet control chip to ensure
communication reliability. This distributive digital output module must be connected to other
modules or a host controller with a network manger built in.
- Built-in Wire-saving FRnet DI/DO control
- High-speed transmission reliability
- Simple synchronization mechanism
- No software overhead on protocol processing
- Supporting broadcasting (1:n data transmission)
- Duplicating output easily
- Fixed I/O scan-time and I/O synchronization
- DIN-Rail
