Product Overview

The Fuji NP1L-RT1 enables remote I/O communication for distributed control applications. This module connects the main controller to remote I/O stations via a dedicated bus. It facilitates efficient data exchange over longer distances for flexible system layouts. The unit integrates seamlessly into Fuji Electric NP1 series programmable controller systems.

Technical Specifications

Physical Dimensions and Mounting

This communication module measures 250 mm in width, 30 mm in height, and 140 mm in depth. The unit weighs approximately 0.38 kg. It plugs directly into a standard NP1 series rack backplane. The front panel includes LED indicators for power, communication status, and station activity. These LEDs provide immediate visual feedback on network health.

Remote I/O Communication and Networking

The NP1L-RT1 establishes communication between the main CPU and remote I/O stations. It uses a dedicated twisted-pair bus for reliable data transmission. The module supports up to 8 remote stations within a 500-meter total distance. It handles up to 512 digital inputs and 512 outputs per system. The polling/response mechanism ensures ordered data exchange between all network nodes.

Performance and Diagnostic Features

This module transfers data at 187.5 kbps for responsive I/O updates. It continuously monitors the communication status and reports any faults. The diagnostic functions detect station disconnection and wire breaks effectively. The module automatically re-establishes communication after transient faults. Furthermore, it stores communication error logs for maintenance purposes.

Installation and System Integration

You can install this module into any available slot in the NP1 series rack. Insert the module carefully into the backplane until it locks securely. Connect the twisted-pair cable to the front terminals with proper shielding. Set the station address switches according to the system layout. Always terminate the cable ends with the correct terminating resistors.

Environmental Compliance

This module carries CE marking for industrial use. It also complies with RoHS environmental directives. The unit suits standard control cabinet installations with IP20 protection.
