Solid State Contactor accepts 4-20 mA control signal.
Press Release Summary:
Able to handle resistive loads up to 25 or 35 A/phase, 3-phase DMA3-6V75T converts analog input into high-speed time proportional output that is compatible with most PLCs or SCADA systems. Switched outputs are zero-crossing solid state back-to-back thyristors to minimize electronic noise. Contactor is suited for applications such as resistive electric heaters, food processing heaters, and heater control on plastics extrusion or blow molding machines.

Power-IO Introduces Improved 4-20 mA Input, Solid State Contactor
Power-io has released an improved DMA3-6V75T solid state contactor. This three phase contactors accepts an analog 4-20mA control signal and provides a 3 phase solid state contactor for resistive loads up to 25 or 35 amps/phase. The contactor converts the analog input into a high speed time proportional output that is directly compatible with most PLCs or SCADA systems. The switched outputs are zero-crossing solid state back-to-back thyristors for long life and minimum electronic noise. Typical applications include: resistive electric heaters, food processing heaters, heater control on plastics extrusion or blow molding machines, and other process heaters.
