RS PRO Timer Relay 11-Contact, 12 to 250 V DC/12 V AC, 240 V AC, 0.1 s to 10 min Time Range, 1-Function, 2 x SPDT 178-5024

RS PRO 178-5024 Timer Relay is an 11-contact plug-in timer relay designed for versatile automation control in industrial and electrical applications. It supports a supply voltage range from 12 to 250 V DC and 12 V and 240 V AC with a single timer function and a time range adjustable from 0.1 seconds up to 10 minutes.

The relay features two single-pole double-throw (SPDT) contacts configured for star-delta timing mode. Timing is initiated by applying supply voltage on specific pins, which immediately triggers the star time during which star contacts remain closed. Upon expiration, the star contacts open followed by a brief pause before the delta contacts close. This sequencing is critical for controlling star-delta motor starters and other phased operations.

The device is user-friendly with a selector switch enabling selection among four different time ranges. Fine tuning within a selected range is possible via a potentiometer, accompanied by green and red LEDs indicating power supply and relay status respectively, enhancing operational feedback.

With robust operating temperature limits of -20°C to 65°C and plug-in 11-pin terminals, the timer relay supports easy replacement and maintenance. The compact form factor with dimensions 48 mm (L) x 74 mm (H) x 24 mm (W) facilitates installation in various control panels and industrial environments.

The RS PRO 178-5024 conforms to important safety and quality standards including CE and RoHS, ensuring compliance with industry regulations. Its construction and manufacturing origin in the United Kingdom affirm high-quality build standards suitable for demanding industrial automation, manufacturing, HVAC, and control relay applications.

Features an 11-pin plug-in design with 2 x SPDT relay outputs. Selectable four time ranges with fine potentiometer adjustment. Dual LED indicators for supply and relay output status. Star-delta mode timing for sequential control operations.
