Schneider 140NOM21100 DIO Head-End Adaptor

140NOM21100 Modicon Quantum DIO Head-End Adaptor

Product Introduction

The 140NOM21100 serves as a dedicated DIO (Distributed I/O) head-end adaptor for the Modicon Quantum automation platform. Specifically, it interfaces between the main Quantum processor and remote I/O sub-stations. This adaptor communicates over a Modbus+ RS485 twisted pair network at 1 Mbit/s. Additionally, it includes an RS232 port for local configuration or auxiliary device connection. The 140NOM21100 supports up to 30 input words and 32 output words per drop. Consequently, it offers efficient data exchange for medium-scale distributed architectures. Its robust design makes it suitable for harsh industrial environments, from manufacturing plants to utilities.

Technical Specifications

The 140NOM21100 provides a reliable communication bridge between the processor and remote racks. Its primary interface is a Modbus+ RS485 port, using a single twisted pair copper cable. This supports high-speed transmission at 1 Mbit/s, ensuring timely I/O updates. A secondary RS232 port is available for local programming or connecting human-machine interfaces. The adaptor manages 30 I/O words for inputs and 32 for outputs. It performs built-in checks to verify data integrity. Specifically, it includes checksum and RAM address verification. The module consumes 780 mA from the bus and dissipates 4 W of power. Its standard format ensures compatibility with Quantum racks.

Compatibility and Supported Racks

The 140NOM21100 works seamlessly with specific remote I/O adaptors. It is directly compatible with the 140CRA21120 and 140CRA21110 modules. These are remote I/O adaptors that connect to the head-end. Together, they form a distributed I/O system controlled by the Quantum processor. The 140NOM21100 cannot be used as a standalone device. It must be paired with these compatible adaptors to function. Consequently, verify your system configuration before ordering. This adaptor is ideal for applications requiring remote I/O distributed across a plant floor.

Environmental Resilience

The 140NOM21100 is built to withstand industrial conditions. Its operating temperature ranges from 32 °F to 140 °F (0 °C to 60 °C). For storage, it tolerates extreme temperatures from -40 °F to 185 °F (-40 °C to 85 °C). The module operates at relative humidity up to 95 %, without condensation. It functions reliably at altitudes of up to 16,404 feet (5,000 meters). Additionally, it resists electrostatic discharge up to 4 kV contact and 8 kV air. It also withstands electromagnetic fields of 9.1 V/m (10 V/m) from 80 to 2000 MHz. Therefore, this adaptor is suitable for power plants, water treatment, and factory automation.

Certifications and Standards

The 140NOM21100 complies with UL 508 standards for industrial control equipment. It holds multiple certifications, including CSA, RMRS, FM Class 1 Division 2, C-tick, and GOST. The FM Class 1 Division 2 certification is particularly valuable. It allows installation in hazardous locations where flammable gases or dust may be present. Consequently, this adaptor is a safe choice for oil and gas, chemical, and mining industries. Its adherence to international standards ensures global acceptance.

Installation Guidelines

Proper installation of the 140NOM21100 is straightforward. First, power down the Quantum rack completely. Insert the adaptor into an available slot on the local Quantum rack. Secure it by tightening the two retaining screws. For remote I/O drops, connect the 140NOM21100 to the 140CRA21120 or 140CRA21110 adaptors. Use shielded twisted-pair cables for the Modbus+ RS485 connection. The maximum cable length depends on baud rate and cable quality. Typically, it can reach up to 1,000 meters with proper termination. Configure the Modbus+ network addresses using the rotary switches on the module. Set the baud rate and parity for the RS232 port if used. Finally, power up the system and verify communication via the processor's programming software. Check the module's LEDs for proper status.
