FUJI NP1L-DN1 DeviceNet Master Module

Module Overview

This DeviceNet master interface module manages communication with slave devices on DeviceNet networks. You can install FUJI NP1L-DN1 directly into any FUJI SPH series PLC rack. The unit acts as the bus master for up to 64 slave nodes. It handles polling and bit-strobe services without CPU intervention.

Module Layout and Components

The PCB integrates a dedicated DeviceNet controller chip for bus management. A 5-pin connector provides CAN_H, CAN_L, and power for the network. Additionally, 148 discrete components include isolation circuits and transceivers. Tantalum capacitors filter the internal power rails for stable operation. Consequently, the module communicates reliably even on long DeviceNet trunk lines.

Installation Process

You can mount FUJI NP1L-DN1 into any standard SPH series rack slot. The 5-pin connector interfaces directly with DeviceNet trunk cables. Furthermore, configuration software sets node addresses and I/O mapping easily. LED indicators show network status, module health, and communication activity clearly.

Performance Advantages

This module selects baud rates from 125 kbps to 500 kbps automatically. It supports polling, bit-strobe, and change-of-state communication modes. Therefore, you can optimize network traffic for different slave device types. The 512-byte I/O buffer also handles large data exchanges with remote stations.

Safety and Compliance

FUJI NP1L-DN1 meets CE and RoHS industrial standards. The board discharges stored energy below 3V within five seconds. Hence, technicians face minimal electrical risk during installation or replacement.
