RM1E23V25 – SSR AS 230V 25A 0-10V

Why Choose the Carlo Gavazzi RM1E23V25 Solid State Relay?

The Carlo Gavazzi RM1E23V25 is a compact and reliable single-pole analogue solid state relay (SSR) designed for proportional control of AC loads in industrial heating, lighting, automation and process-control applications. As part of the established Carlo Gavazzi RM1E series, it uses phase-angle control to regulate the power delivered to suitable resistive and slightly inductive loads.

This solid state relay provides electronic proportional switching without mechanical contacts, helping eliminate contact wear while delivering quiet and reliable operation. The 0–10 V DC analogue control input determines the output switching point within the AC sine wave, allowing proportional power control from suitable PLCs, process controllers and automation systems. The voltage-controlled RM1E version uses an external 24 V DC supply.

With a rated operational current of 25 A AC-51, an operating voltage range of 90–265 V AC and a 0–10 V DC control input, the RM1E23V25 is well suited to proportional control of AC loads. Its panel-mount construction and screw terminals with captive clamp provide straightforward installation in electrical control panels when used with an appropriately selected heatsink.

Precise Proportional Control for Industrial Loads

Analogue solid state relays such as the Carlo Gavazzi RM1E23V25 use semiconductor switching to regulate AC load power according to an analogue control signal. Phase-angle control varies the conduction angle of the AC waveform, allowing the connected load to be controlled proportionally rather than simply switched fully on or off. A 0 V DC input corresponds to zero output power, while 10 V DC corresponds to full output power with a near-linear power response.

The RM1E series is designed for industrial applications including heaters, lighting and slightly inductive loads such as small fans. The 0–10 V DC control interface makes the RM1E23V25 particularly suitable for process-control systems where output power needs to follow a controller or PLC analogue signal. The relay switches off when the output current crosses zero and switches on according to the applied control input.

Typical Applications

• Industrial heating and temperature control systems.
• Proportional control of resistive heating elements.
• Industrial lighting control.
• Suitable slightly inductive AC loads such as small fans.
• PLC and process-controller analogue output applications.
• Soft turn-on of high-power incandescent lamps.
• Industrial automation and process-control equipment.
• Electrical control panels and industrial machinery.
