Macromatic THR-3856U Multifunction Time Delay Relay, Square, 4 Functions 12 to 125V DC, 24 to 240V AC

Industrial Timing Relay for Automation

The Macromatic THR-3856U is a multi-function encapsulated timing relay designed for industrial electrical controls and automation. It operates on a wide input voltage range of 12 to 125V DC and 24 to 240V AC. The unit features a square base shape with a transparent housing and uses screw terminals for secure electrical connections. Four selectable delay functions are configured via an onboard DIP switch adjustment method.

Suits Panels Needing Flexible Timing Logic

This relay suits installers who need a single device covering delayed interval, repeat cycle off first, repeat cycle on first, and triggered delayed interval modes. The SPDT contact form handles 24 A at 240V AC or 12 A at 125V DC for direct load switching. Buyers who require more than four timing functions or a different contact arrangement should look at alternative control modules. The minimum time setting of .1 sec covers fast cycling applications.

Fits Standard Square Base Sockets in Cabinets

The square base plugs into compatible industrial sockets for quick installation inside control cabinets. Screw terminal connections accept standard wiring without special tools. The wide coil voltage tolerance frees up inventory by replacing multiple single-voltage relays. Encapsulated construction protects internal components in harsh environments. The transparent cover allows visual inspection of the DIP switch settings during commissioning or maintenance.
