Why Choose the Carlo Gavazzi RM1E23AA50 Solid State Relay?
The Carlo Gavazzi RM1E23AA50 is a robust single-pole analogue solid state relay (SSR) designed for proportional control of AC loads in industrial heating, lighting and automation applications. As part of the established Carlo Gavazzi RM1E series, it uses phase-angle control to provide precise regulation of 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 4–20 mA analogue control input determines the output conduction according to the applied control signal, making the relay suitable for integration with PLCs, process controllers and other industrial automation equipment.
With a rated operational current of 50 A AC-51, an operating voltage range of 90–280 V AC and a 4–20 mA DC control input, the RM1E23AA50 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 RM1E23AA50 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.
The RM1E series is designed for industrial applications including heaters, lighting and slightly inductive loads such as small fans. The 4–20 mA control interface makes the RM1E23AA50 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.
- Electrical control panels and industrial automation systems.
