Schneider 140XCA71709 Backplane Expander Cable 3m

140XCA71709 3-Meter Backplane Expander Cable for Modicon Quantum

Product Introduction

The 140XCA71709 is a genuine backplane expander cable from Schneider Electric. It belongs to the Modicon Quantum automation platform. This cable measures exactly 3 meters (9.84 feet) in length. Therefore, it provides enough slack to arrange components across different cabinets or larger racks.

Specifically, this cable works exclusively with the 140XBE10000 backplane expander. Together, they extend the Quantum backplane beyond a single chassis. Additionally, the 140XCA71709 supports the Modbus TCP/IP protocol. This feature ensures that remote I/O racks communicate reliably with the main controller.

Technical Specifications

The 140XCA71709 delivers consistent performance under standard industrial conditions. Its key electrical and communication parameters are listed below.

• Cable Length: 3 meters (9.84 feet)

• Input Voltage: 24V DC

• Communication Interface: Modbus TCP/IP

• Compatibility: 140XBE10000 backplane expander only

• UPC: 785901173458

• GTIN: 3595860026019

Furthermore, this cable uses high-quality shielding. As a result, it resists electromagnetic interference in noisy environments.

Mechanical and Environmental Ratings

The 140XCA71709 operates reliably across a broad range of conditions. You can use it in both cold and moderately hot locations.

• Operating Temperature: -20°C to 60°C

• Storage Temperature: -40°C to 85°C

• Altitude Range: Up to 2000 meters (6561 feet)

• IP Rating: IP20 (indoor use, dust protection)

• Net Weight: 2.00 lbs (0.91 kg)

Moreover, the IP20 rating makes this cable suitable for control cabinets and clean equipment rooms. However, avoid installing it in wet or dusty outdoor areas without an enclosure.

Installation Guidelines for 140XCA71709

Installing the 140XCA71709 requires careful planning. First, mount your main Quantum rack and the remote rack with the 140XBE10000 expander. Next, route the cable between the two locations. Do not bend it sharply or place heavy objects on top of it.

Then, connect one end of the 140XCA71709 to the backplane expander in the main rack. Connect the other end to the 140XBE10000 in the remote rack. Finally, secure the cable using zip ties or cable ducts. Leave enough slack near the connectors to avoid strain.

• Keep the cable away from high-voltage power lines.

• Minimum bend radius: 10x cable diameter.

• Power off all racks before connecting or disconnecting.

Therefore, a clean installation prevents signal loss and mechanical damage.

Common Applications

The 140XCA71709 is a key component for distributed control systems. For instance, it is widely used in water treatment plants where I/O racks must be placed near sensors. Additionally, it serves the automotive industry for assembly line monitoring.

Other typical applications include:

• Material handling systems (conveyors and sorters)

• Building management systems (HVAC and lighting)

• Power distribution centers

• Food and beverage processing lines

Because it supports Modbus TCP/IP, the 140XCA71709 integrates easily with SCADA systems. Meanwhile, its 3-meter length offers flexibility without excessive signal degradation.

Frequently Asked Questions (FAQ)

1. Can I use the 140XCA71709 with other backplane expanders?
No. The 140XCA71709 is designed only for the 140XBE10000 backplane expander. Using it with other models may cause communication failures or damage.

2. How long is the 140XCA71709 cable?
The cable measures exactly 3 meters (9.84 feet). This length is measured from connector tip to connector tip.

3. Is the 140XCA71709 suitable for outdoor use?
No. Its IP20 rating means it is for indoor, dry locations only. For outdoor use, place the cable inside a conduit or an IP65-rated enclosure.

4. What protocol does the 140XCA71709 support?
It supports the Modbus TCP/IP protocol. This allows remote Quantum racks to communicate over Ethernet-based backplane extensions.

5. Can I cut or splice the 140XCA71709 to make it shorter?
No. Cutting or splicing the cable will void its warranty and likely cause signal reflections or data errors. Always use the original length as delivered.
