Carlo Gavazzi Control Cables and Domestic Solution Selection Guide

In industrial automation and control systems, control cables serve as the key bridge for stable connections between devices such as PLCs (Programmable Logic Controllers), relays, and sensors. With the continuous improvement of automation equipment performance, higher requirements have been placed on the transmission stability, anti-interference, and compatibility of control cables. Among numerous well-known automation component brands, Carlo Gavazzi Inc. holds a significant position in the global industrial control market thanks to its extensive product portfolio of relays, monitoring relays, and solid-state relays. Carlo Gavazzi is a global manufacturer of automation components, covering a wide range of fields from sensors, solid-state relays, monitoring relays, current transmitters to various industrial control modules, and widely used in industrial automation, power monitoring, and energy management scenarios. Although the brand itself does not focus on cable production, its relays and配套 control equipment (solid-state relays, monitoring relays) require high-quality control cables for precise signal transmission when interfacing with PLCs, which is the foundation for product performance.

One, matching scheme of control cables with Carlo Gavazzi relays/PLC
In control system design, when matching PLC control outputs to relay inputs (including Carlo Gavazzi series relays), several key factors need to be considered:
The cable specification should match the signal category: PLC output signals (such as 24V DC control signals) require the selection of control cables with corresponding impedance and shielding levels to reduce noise interference and improve signal integrity, especially when connected to Carlo Gavazzi relay DIN rail modules.
• Shielding layer and anti-interference design: When deploying control cables in complex industrial environments (next to motors, high-power equipment), shielding design can significantly reduce the impact of EMI (electromagnetic interference) on the PLC and Carlo Gavazzi solid-state relay control circuit.
Connector compatibility: Choosing M8/M12 cable connectors compatible with the PLC can enhance wiring reliability and maintenance efficiency when using Carlo Gavazzi solid-state relays or supervisory relay modules.
Reasonable matching not only guarantees signal stability but also reduces maintenance costs, which is an important aspect of industrial automation system design.

Section 2: Selection, Compatibility, and Alternative Solutions Reference and Recommendations
For wiring requirements of Carlo Gavazzi control devices (such as monitoring relays, solid-state relays, etc.) with PLCs, we propose the following selection and compatibility recommendations:
Selection Suggestions
It is recommended to use multi-core control cables with shielding layers (such as 18AWG and above specifications) which are suitable for connecting PLCs with Carlo Gavazzi signal input/output terminals, effectively reducing interference. When connecting Carlo Gavazzi DIN rail relays, use standard industrial connectors with shielded cables to enhance the reliability of on-site connections.
 Compatibility reference scheme
For a 24V DC output signal PLC, you can choose a 24V DC relay series (such as Carlo Gavazzi solid-state relay or monitor relay series) and match it with a noise-resistant shielded control cable. In high-noise environments (such as large motor control cabinets), it is recommended to use shielded cables and配合 metal connector shell to enhance the anti-interference capability.
  Domestic alternative reference
Currently, there are many domestic control cables and industrial connectors on the market that can provide high-quality solutions compatible with Carlo Gavazzi control equipment. Under conditions such as meeting PLC output signal specifications like 24V and 5V control voltage, these domestic cables are increasingly improving in terms of durability, shielding effect, and cost control, making them a worthy alternative choice to pay attention to.

Carlo Gavazzi's relays and related automation control products have reliable performance and a wide range of application scenarios in the field of industrial control. The efficient connection with PLC systems not only depends on the correct selection scheme but also cannot be separated from high-quality control cables and reasonable connection schemes. When designing automation systems, combining the characteristics of Carlo Gavazzi's equipment with the electrical performance of control cables can build stable and anti-interference control circuits, providing a long-term reliable operation foundation for industrial sites.
