Schneider Electric Harmony Time Series Plug In Timer Relay, 230V ac, 4-Contact, 0.1 s → 100h

This miniature timer relay from Schneider Electric is a versatile device that lets you set an 'on' delay of between 0.1 seconds and 100 hours for up to four different circuits. Setting the time delay is as simple as turning the dial and switching on the power supply. The unit mounts easily onto a DIN rail using a relay socket (884-1310) for ease of installation. Thanks to its wide operating temperature range of -20°C to +60°C, it's suitable for use in harsh industrial conditions.

• Mechanical lifespan of 100,000 operations for long-lasting, reliable performance
• Compact dimensions of 59.5 (L) x 27 (W) x 21mm (D) for installation in areas where space is limited
• Silver-nickel contact material for high conductivity and corrosion resistance, ensuring a reliable connection

• Irrigation applications
• Warehouses
• Food and beverage processing
• Industrial process control

A small AC (alternating current) motor is turned at a rate determined by the frequency of the AC power supply. Gears then drive a shaft at the desired rate, which turns the timer's cam.
