PLCs, Power Supplies & Others

The Schneider Electric 140NRP95400 is a fiber optic repeater module for the Modicon Quantum platform. This device reliably extends the S908 Remote I/O network using multi-mode optical fiber. It operates with a standard 5 VDC power supply and draws 1 amp of current. Consequently, the module provides excellent electrical isolation and noise immunity for long-distance communication.

Optical Communication and Electrical Specifications

This repeater module features two independent communication channels for robust data transmission. It specifically supports the S908 RIO protocol over a multi-mode (MM) fiber optic backbone. The module requires a bus current of 700 milliamps from the Quantum backplane to operate. Its power dissipation is rated at a low 5 watts, ensuring efficient performance within the rack.

Furthermore, the 140NRP95400 integrates clear local signaling via status LEDs. These indicators provide immediate visual feedback on power and channel activity. The module uses ST-type connectors for reliable and secure fiber optic cable termination.

Physical Design and System Integration

The module installs directly into a standard Modicon Quantum rack using its backplane connector. Its compact form factor optimizes valuable space within industrial control cabinets. The robust construction ensures reliable operation in typical manufacturing and process environments.

The fiber optic design eliminates concerns about electromagnetic interference (EMI). It also enables significantly longer distances between the CPU and remote I/O drops. This makes the 140NRP95400 ideal for plants with widely distributed equipment. Professionals can source such specialized communication modules from trusted industrial suppliers globally.
