FUJI NP1L-TS1 Communication Module

This communication module provides high-speed data exchange for Fuji MICREX-SX PLC systems. The FUJI NP1L-TS1 connects controllers to remote I/O racks and peripheral devices. Dual communication ports support multiple protocols for flexible system integration. Consequently, automation engineers can link HMIs, drives, and SCADA systems through a single module.

Technical Specifications of the Communication Module

The FUJI NP1L-TS1 measures 113.6 mm in width and 90 mm in height. Its depth reaches 76 mm for standard MICREX-SX rack mounting. The module weighs approximately 0.26 kg including all communication and isolation circuitry. A single front panel LED array shows port activity, link status, and error conditions. The front side features two 9-pin D-sub connectors for RS-232 and RS-422/485 ports. This design stores minimal energy in small decoupling capacitors only. Therefore, the module contains no batteries or large energy storage elements.

Functional Features and Network Integration

The FUJI NP1L-TS1 allows you to configure each port independently for different protocols. You can use one port for HMI communication and the second for drive control. The module automatically buffers incoming data for background processing by the CPU. Integrated diagnostics report communication errors and line break conditions. Consequently, operators receive immediate alerts for network failures or cable disconnections.

Installation and System Configuration

You must install this communication module into a standard MICREX-SX rack slot. The FUJI NP1L-TS1 communicates with the CPU through the high-speed backplane. Shielded cables connect the module to external devices up to 1200 meters away. The module uses DIP switches for setting station addresses and baud rates. Always verify cable shielding and grounding before commissioning the communication network.

Maintenance and Operational Benefits

Because the FUJI NP1L-TS1 stores no battery-backed data, it needs no periodic battery changes. Technicians can replace the module without losing any communication parameters. The module retains all port settings and protocol configurations in non-volatile memory. Consequently, maintenance remains simple and reliable for plant-wide communication networks.
