Why Choose the Carlo Gavazzi RM1E23AA100 Solid State Relay?
The Carlo Gavazzi RM1E23AA100 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 providing quiet and reliable operation. The 4–20 mA analogue control input allows the relay output to be regulated according to the applied control signal, making it suitable for integration with PLCs, process controllers and other industrial automation equipment.
With a rated operational current of 100 A AC-51, a 90–280 V AC operating voltage range and a 4–20 mA DC control input, the RM1E23AA100 is well suited to high-current heating and load-control applications. 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 RM1E23AA100 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 RM1E23AA100 particularly suitable for process-control systems where output power needs to follow a controller or PLC analogue signal.
Typical Applications
- Industrial heating and temperature control systems.
- Proportional control of resistive heating elements.
- Industrial lighting control.
- Small fans and suitable slightly inductive loads.
- PLC and process-controller analogue output applications.
- Soft turn-on of high-power incandescent lamps.
- Electrical control panels and industrial automation systems.
