FR-2054T 8-channel isolated digital output and 8-channel isolated digital input module

FR-2054T 8-channel isolated digital output and 8-channel isolated digital input module

Features

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
