Overview
The Carlo Gavazzi RM1E23AA25 is a 1-pole, panel-mount analog switching solid state relay designed for proportional load control in industrial automation and process control applications. Operating voltage ranges from 90–280 VAC, with a rated current of 25 A AC and 4–20 mAdc analog input. This SSR employs phase-angle control technology to deliver smooth, variable power modulation without mechanical contact bounce or wear.
Key Features
- 1-pole AC solid-state relay in the RM series
- Analogue switching via phase angle control principle; output switching point depends on control input (4–20mA or 0–10VDC)
- 4mA or 0VDC corresponds to zero output power; 20mA or 10VDC corresponds to full output power with near-linear response
- Integral snubber network and polarized lockable control connector for safe connection in voltage-controlled version
- Built-in overvoltage protection
- Panel-mount design with screw-type power terminals

Typical Applications
These relays offer analog switching (phase-angle control) for resistive and slightly inductive load applications. Common uses include:
- Heaters, lighting, and slightly inductive loads such as small fans
- Soft turn-on of high-power incandescent lamps
- Process temperature control
- Power regulation and load dimming
- Industrial HVAC and thermal equipment
Compatibility & Replacements
Compatible With
- Industrial PLC analog control outputs (0–10VDC or 4–20mA)
- Variable frequency drives and soft starters
- Temperature controllers with analog 4–20mA or 0–10VDC outputs
