With six DIP switches, these new THR-3 Series relays are easy to program, feature four of the
most common time delay functions built-in, and include universal voltage.
Macromatic announced the THR-3 programmable encapsulated time delay relay series. This
series is comprised of the THR-3816U, THR-3836U and the THR-3856U models. Each model has
multi-function capability with four of the most common time delay functions built-in. All models
come with a programmable time delay that includes four time ranges covering 0.1S to 100M
(1,000M on THR-3856U). Choices include onboard or remote adjust adjustment of time delay. Now,
even a timer with a fixed delay can be replaced with one of these products.
“Distributors can literally replace thousands of products on their shelves with one of these three
THR-3 Series models,” said Macromatic Industrial Controls President, John Perdue. “It streamlines
and controls inventory immensely. Now, instead of having to order one piece, worrying about
meeting order minimums and waiting two weeks or longer, distributors can satisfy their customer
immediately from their stock.”
The THR-3 series has a 10A SPDT relay output which is used when a higher current carrying and/or
switching capacity are required or when switching a horsepower-rated device. It is designed with a
universal input voltage of 24-240VAC & 12-125VDC which covers almost any application. These
units are encapsulated for protection against harsh environments.
Functions available vary by each model.
- The THR-3816U functions include: on delay, off delay, interval and single shot
- The THR-3836U functions include: flasher off, flasher on, watchdog, one shot falling edge
- The THR-3856U functions include: repeat cycle off, repeat cycle on, delayed interval, and
delayed interval (triggered)
Other encapsulated time delay relays offered by Macromatic are the THS Solid State Output, THL
Solid State Output Inline, and the THR Relay Output. Macromatic’s THx Series Time Delay Relays
utilize a microprocessor-based design for greater performance and maximum flexibility. All products
are encapsulated for protection against harsh environments and are available in adjustable, fixed
onboard or remote time delay.
