Protect 24V AC/DC control signals with Weidmuller VSSC4 CL surge protection. Slim DIN-rail design for reliable automation and measurement systems.
Weidmueller VSSC4 CL FG24VAC/DC0.5A surge protection is a compact DIN-rail mounted device designed to protect 24 V AC/DC measurement and control signal lines from transient overvoltage conditions. It is optimized for floating-ground signal circuits and supports current loops up to 0.5 A, making it suitable for industrial automation, process control, and building automation systems. The slim 6.2 mm housing allows installation close to sensitive I&C equipment, reducing exposure to surge energy. This design ensures reliable signal protection while maintaining stable system operation in limited cabinet space.
In real-world control cabinets, the VSSC4 CL FG24VAC/DC0.5A helps prevent damage caused by lightning effects and switching surges on field signal wiring. By safely limiting transient voltages before they reach PLC inputs, sensors, or transmitters, it reduces unexpected downtime and maintenance costs. Support for both AC and DC signals simplifies integration across different control architectures, while compatibility with communication-enabled instrumentation ensures signal quality is preserved. The defined protective response under fault conditions prioritizes downstream device safety, delivering higher system availability and long-term operational reliability.
Why Weidmueller VSSC4 CL FG24VAC/DC0.5A?
The Weidmueller VSSC4 CL FG24VAC/DC0.5A is chosen when signal reliability is non-negotiable. Its ultra-slim DIN-rail design allows engineers to add high-performance surge protection exactly where sensitive 24 V signal lines enter the control cabinet. Built for floating-ground circuits, it combines strong surge-handling capability with minimal impact on signal quality, making it ideal for modern automation systems where space, precision, and long-term stability are critical.
What problem does it solve?
It solves the hidden but costly problem of transient overvoltages damaging low-voltage control and measurement signals. Lightning-induced surges, switching operations, and electromagnetic interference can silently degrade PLC inputs, sensors, and transmitters. This surge protector absorbs and limits harmful voltage spikes before they reach connected devices, preventing unexpected failures, inaccurate measurements, and unplanned downtime in industrial and building automation environments.

In process industries such as water treatment, oil and gas, and chemical production, low-voltage sensors transmit essential measurements to control systems through long cable runs. These cables are vulnerable to electrical noise, switching disturbances, and surge events. Installing the Weidmueller VSSC4 CL FG24VAC/DC0.5A close to the control equipment limits transient voltages before they reach sensitive inputs. Its floating-ground circuit design helps avoid ground-related interference, while the narrow DIN-rail footprint allows easy integration in crowded panels. This approach improves measurement stability, reduces sensor damage, and supports continuous operation in electrically demanding environments.
Automated machinery depends on reliable PLC inputs to coordinate sensors, actuators, and control logic. Voltage spikes from motors, relays, or nearby high-power equipment can disrupt these signals and damage input modules. The Weidmueller VSSC4 CL FG24VAC/DC0.5A is used between field wiring and PLC terminals to absorb and limit these transient events. Its ability to handle both AC and DC control signals simplifies deployment across different machine designs. By reducing electrical stress on PLC inputs, manufacturers experience fewer unexpected stoppages, lower replacement costs, and improved long-term system reliability.
Building automation systems rely heavily on 24 V control circuits for HVAC, lighting control, and environmental monitoring. Long wiring routes and frequent switching loads increase exposure to electrical disturbances. Integrating the Weidmueller VSSC4 CL FG24VAC/DC0.5A into control cabinets protects these signal lines from surge-related failures. The compact housing supports high-density installations, while fast protective action preserves stable communication between controllers and field devices. Facility operators benefit from fewer control disruptions, improved occupant comfort, and reduced maintenance caused by damaged controllers or sensors.
Energy distribution and infrastructure monitoring systems use low-voltage signals to track equipment status and operating conditions. These installations often operate in harsh electrical environments where surges and interference are common. By placing the Weidmueller VSSC4 CL FG24VAC/DC0.5A at signal entry points, transient energy is safely diverted away from monitoring electronics. The high surge-handling capability ensures signal continuity without compromising measurement accuracy. This supports reliable data collection, early fault detection, and increased operational confidence in critical energy and infrastructure systems.
