RSR58 – Solid State Relays with Dual AC Output Channels
RSR58 – Solid State Relays with Dual AC Output Channels
RSR58 – A compact and reliable solid state relay with dual AC output channels, designed for applications requiring precise control of high-power loads and high resistance to environmental conditions.
Performance and Reliability in Dual Channels
The RSR58 model is engineered for efficient and safe control of two independent AC loads, making it an ideal solution for high-current-demand applications – from the food and chemical industries to HVAC systems and lighting installations.
The SCR-based (thyristor) output ensures fast and spark-free switching. Additionally, the zero-crossing turn-on function significantly reduces EMC interference and extends the lifetime of connected equipment.
Key Technical Features:
- Control voltage range (DC): 4...32 V DC
- Three load voltage versions:
- 24...280 V AC
- 24...530 V AC
- 24...660 V AC
- Three load current levels:
- 25 A
- 50 A
- 75 A
- Surge current capacity: up to 750 A (10 ms)
- Advanced optical isolation: 4,000 Vrms
Mounting Options
The RSR58 solid-state relay is available in variants designed for:
- Baseplate mounting,
- Mounting on RH series heatsinks (RH08, RH08-F, RH16-F),
This enables precise thermal adaptation based on the application. Thermal characteristics are available to assist in proper heatsink selection, depending on load and ambient operating temperature.
Design & Installation
Equipped with mechanical screw terminals (M3 for input, M4 for output) and a robust IP20-rated enclosure, the relay ensures safe and straightforward installation and maintenance.
Additionally, front-mounted LED indicators for each output channel provide immediate visual feedback on the relay’s operational status, significantly reducing diagnostics and service time.
Applications
The RSR58 is built for environments that demand high availability and strong interference resistance. It is especially suitable for:
- Heating, ventilation, and air conditioning (HVAC) systems
- Process automation
- Food and plastics industries
- Production lines and industrial machinery
- Lighting control and temperature chambers
RSR58 – Reliable Switching in a Compact Form
With two independent output channels, a wide range of permissible loads, and broad operating voltage compatibility, the RSR58 is an ideal choice for system integrators and control engineers seeking a compact yet powerful switching interface.
Easy mounting, maintenance-free operation, and high manufacturing quality define this modern SSR (Solid State Relay) from Relpol.
