Celduc SC942110 Solid State Relay 25A 12–280VAC 4–30VDC Control Panel Mount

Brand: Celduc Relais, France.
Model: SC942110 solid state relay, standard hockey‑puck style housing, intended to be used with a heatsink to achieve full current rating.

Condition: New old stock / never used; screw terminals are bright with no wiring marks and the base plate only shows minor storage scratches. Relay will be supplied exactly as shown, without heatsink or original packaging unless otherwise pictured.

Technical specifications (from manufacturer data):

• Relay type: Single‑phase solid state relay, SPST‑NO (1 Form A).

• Load voltage range: 12–280 VAC, up to 600 V peak.

• Rated load current: 25 A continuous with appropriate heatsink, AC‑51 resistive loads.

• Control input: 4–30 VDC, optically isolated control.

• Switching mode: Zero‑cross for low EMI and reduced inrush on resistive loads.

• Operating temperature range: approximately −40 to +100 °C (with suitable heatsink and derating).

• Mounting: Panel mount with single M5/M6 fixing hole and four screw power/control terminals.

Main features and applications:

• Reliable, maintenance‑free switching for resistive heaters, lighting, small motors, solenoids and general industrial loads.

• Compact form factor makes it ideal for OEM machinery, heaters, ovens, packaging and plastics equipment where long life and silent operation are required.

Background / usage notes:
SC9‑series Celduc relays are widely used in automation panels and are compatible with most PLC and temperature‑controller transistor outputs providing 4–30 VDC control signals. When installing, always use a suitable heatsink, observe tightening torques on terminals and ensure load current and ambient temperature stay within the datasheet derating curves.
