In industrial fluid systems, precise actuation of solenoid valves is essential for safety and performance. The PLC-RPT-230AC/21-21/SO46/HI serves as an interface between low-voltage PLC outputs and high-voltage valve circuits. Its 230 V AC coil and reinforced insulation safely manage the power transfer while shielding control electronics from voltage surges. With two changeover contacts, it enables both main actuation and feedback signaling. This combination ensures stable and reliable valve operation even in environments with high electrical noise or vibration.
Production lines often operate across multiple voltage domains—such as 24 V logic and 230 V actuator circuits—which can introduce interference. This relay module provides safe galvanic separation up to 6 kV, allowing smooth signal transmission without cross-talk or damage. It effectively protects sensitive PLC hardware from overvoltage or transient spikes generated by large motors or heaters. Its durable contact design guarantees long service life, keeping the automation line stable and minimizing costly downtime.
For modern building automation systems that integrate lighting, HVAC, and energy monitoring, compact and efficient switching components are vital. The slim 14 mm width of this relay module allows more channels to fit into control cabinets. The push-in terminals enable quick, tool-free wiring, while the LED indicator provides at-a-glance system feedback. Its dual contact design can simultaneously drive two different loads or provide real-time signal verification, ensuring precise control with minimal wiring complexity.
Marine control systems demand high endurance and strong electrical isolation due to continuous vibration and humidity. The PLC-RPT-230AC/21-21/SO46/HI’s rugged construction and 30-million-cycle lifespan make it ideal for these challenging environments. It can manage control signals for pumps, generators, or navigation aids, ensuring consistent performance under fluctuating voltage or moisture exposure. By maintaining reliable isolation between circuits, it enhances operational safety and reduces the risk of system faults during critical operations.
