Product Overview:
The 43134‑03 solid state contactor is an internal power switching module used in Rotork actuators. It replaces traditional electromechanical contactors with a semiconductor‑based design, providing silent, wear‑free, and reliable motor switching. It is critical for actuator motor control, torque regulation, and protection.
Specifications (typical for Rotork SSC boards):
| Feature | Specification |

| Function | Motor switching and protection |
| Switching Type | Solid state (triac/thyristor based) |
| Load Voltage | 110–480 VAC (depending on actuator model) |
| Load Current | 10–25 A continuous (model dependent) |
| Control Voltage | 24 VDC logic from actuator control board |
| Isolation | Optical isolation between control and power circuits |
| Protection | Over‑voltage, over‑current, thermal shutdown |
| Operating Temp | −20 °C to +70 °C |
| Compliance | IEC 60947, IP68 (when installed in actuator housing) |
