In today’s automation and control systems, surge protection is not optional—it’s essential. Whether from lightning strikes, switching transients, or power disruptions, voltage surges can damage sensitive electronics, leading to costly downtime and maintenance.
The Phoenix Contact 2900576, part of the VAL-MS series, offers a compact, reliable, and standards-compliant surge protection solution for 24V DC systems. It’s designed specifically for protecting power supply lines in industrial control cabinets, PLCs, and sensor/actuator networks.
The 2900576 (VAL-MS 24 ST) is a Type 2 surge protection device that safeguards 24V DC circuits from overvoltage events. Housed in a compact, DIN rail-mountable module, it provides high-performance transient suppression while taking up minimal panel space.
Key Technical Features
- Nominal Voltage: 24V DC
- Maximum Continuous Voltage (Uc): 28.6V DC
- Voltage Protection Level (Up): ≤ 60V
- Discharge Current (Imax): Up to 20 kA (8/20 µs waveform)
- Response Time: < 25 ns
- Status Indicator: Visual fault indicator enables fast diagnostics
A single transient event can damage downstream electronics, trip power supplies, or disrupt operations. By integrating the Phoenix Contact 2900576, you protect critical control voltage lines from harmful overvoltages—improving system reliability and reducing costly downtime.
Where It’s Commonly Used
The 2900576 is ideal for:
- 24V power lines in control cabinets
- PLC input/output modules
- Sensor and actuator supply lines
- Building automation systems
- Industrial machinery and process control systems
Engineers choose the VAL-MS series when they need fast-acting protection with minimal insertion loss and high surge-handling capacity—all in a modular, service-friendly design.
