The Carlo Gavazzi RM1A48A50 solid state relay is part of the RM1A series of automation products, and one of the most widely used range of solid state relays in the world today. Designed for superior performance and reliability in demanding industrial applications, the RM1A48A50 solid state relay utilizes back-to-back SCRs to switch power to/from AC loads. This minimizes overall power dissipation and increases the solid state relay’s ability to withstand surge currents.
The RM1A48A50 can reliably switch 50 amp loads at line voltages between 42Vac and 530Vac in a 40°C ambient. The input of the RM1A48A50 can accept control signals between 20Vac and 280Vac, or 22Vdc and 48Vdc. The control circuit will draw less than 20mA at the maximum specified input voltage.
The RM1A48A50 solid state relay uses zero-crossing optical isolators to trigger the output SCRs. When an input signal is applied, the output of the solid state relay will not conduct load current until the AC mains passes through the zero-crossing point of the sine wave. This greatly reduces inrush currents and minimizes the level of conducted emissions coupled onto the AC mains by the solid state relay.
Typical Carlo Gavazzi solid state relay applications include resistive heating control, motor control and some lighting control systems.
Additional features and benefits of the Carlo Gavazzi RM1A48A50 solid state relay include:
- Direct bond copper (DBC) substrate for superior thermal performance
- Integrated overvoltage protection
- Epoxy-free design to eliminate stress caused by the expansion and contraction of epoxy during normal operation
- Removable IP20 touch-safe cover
- Agency approvals: cURus, CSA, CCC, EAC, and CE
A heat sink and thermal compound are normally required to prevent a solid state relay from overheating during normal operation. HBControls can pre-assemble the RM1A48A50 solid state relay onto a wide range of DIN or panel mount heat sinks.
