Industrial Applications

1. Industrial Furnace Temperature Regulation

Used to precisely control the power supplied to electric heating elements in an industrial furnace or oven. The SSR is driven by a PID temperature controller's DC output.

Problem Solved

Provides fast, silent, and reliable switching compared to mechanical contactors, which wear out quickly under frequent cycling. The zero-cross function (rated for 200-480VAC loads) reduces electrical noise and thermal stress on the 15A heating elements, ensuring stable temperatures and longer heater life.

2. Plastic Injection Molding Machine Heater Control

Integrated into the control panel of a plastic injection molding machine to manage the multiple heater bands that melt the plastic resin.

Problem Solved

The G3PE-515B's compact, DIN-rail mountable design (22.5mm width) allows for high-density placement in space-constrained control cabinets. Its 15A rating is sufficient for individual heater bands, and the solid-state design offers the high reliability needed for continuous, 24/7 manufacturing operations without the maintenance downtime associated with electromechanical relays.

3. Semiconductor Manufacturing Wafer Processing Equipment

Controls the resistive heaters within a wafer processing chamber for thermal processes like annealing or chemical vapor deposition (CVD).

Problem Solved

Semiconductor processes demand extremely precise and clean power switching. The SSR's solid-state nature eliminates the arcing and particle generation common with mechanical relays, preventing contamination. The 12-24VDC input is compatible with standard low-voltage control signals from the equipment's master controller, ensuring precise power delivery to heaters rated up to 480VAC.
