RS PRO Timer Relay 8-Contact DPDT 12 to 250 V DC/12V, 240 V AC, 0.1 s to 10 Days 1-Function 178-5023

The RS PRO 178-5023 Timer Relay is an advanced, 8-contact DPDT asymmetrical cyclic timer designed for use in industrial, electrical automation, manufacturing, and control systems. It accommodates a broad voltage supply from 12 to 250 V DC and up to 240 V AC, making it highly versatile for varied power sources.

This 8-pin plug-in timer features a selector switch enabling users to select from eight different time ranges spanning 1 second to 100 days. Fine time adjustments for both timing intervals T1 and T2 are independently set via dual percentage potentiometers, allowing precise control over energisation and de-energisation timings.

Its operation initiates timing as soon as supply is applied to pins 2 and 7 with a cycle that first energises and then de-energises relay contacts, repeating continuously while power is maintained. Dual LED indicators provide clear status feedback: green denotes supply presence, while red indicates relay activation.

Compact with a length of 48mm, height of 74mm, and width of 24mm, this timer relay fits efficiently into control panels, offering a robust and reliable solution for cyclic timing functions required in industrial automation, electrical control, HVAC systems, and water treatment plants.

This timer relay supports multiple voltage types, including DC and AC supply between 12 and 250 V and up to 240 V AC. Equipped with 8 contacts configured as DPDT (Double Pole Double Throw) suitable for diverse switching applications.

The device supports a single timer function with adjustable timing intervals over an extensive range (0.1 seconds to 10 days). High durability and compliance with multiple standards (CE, RoHS, EN61000-6-4, and EN61010-1) guarantee safe integration into industrial environments.

Operating temperature from -20°C to 65°C ensures dependable performance in harsh conditions. Dual LEDs for easy visual status indication enhance operational monitoring and maintenance. Plug-in terminal type with 8 pins facilitates easy installation and replacement in relay sockets.

The RS PRO 178-5023 Timer Relay enables precise timing control essential for automation processes, cyclic switching, and sequence management in diverse industrial, laboratory, and commercial electrical applications. Its reliable design and wide voltage operation range make it an excellent choice for specialists seeking robust Timer Relay solutions.
