TIME DELAY RELAYS

Macromatic offers a wide variety of Time Delay Relays (sometimes referred to as time relays or timers). Four types of mounting configurations for time delay relays are available. Each time relay series has a variety of functions, time-setting methods & output configurations. Pick the exact time delay relay product to meet your requirements.

Largest Selection of Time Delay Relays in the Industry

Time Delay Relays with plug-in enclosures use 8- or 11-pin octal sockets that mount on 35 mm DIN-rail or to a panel with two screws. Encapsulated designs are compact, low-cost, and resistant to the effects of harsh environments. DIN-rail mounted timers are easily installed, saving space and installation costs. Relays with DIN-16 mounting can be door mounted for easy access without opening the door. If you need help picking the right relay, contact us.

PLUG-IN

The time delay on TR-5 and TR-6 Series Relays is analog set. TD-7 Series Relays use pushbutton thumbwheels to set the time range, time delay, and function. TD-8 Series Relays use two 10-positon DIP-switches for programming.

ENCAPSULATED

THR-1 and THR-3 Series have 10A SPDT relay output. THS-1, THL-1 and THL-8 have 1 A Normally Open solid-state output. A 10-position DIP-switch is used to program the THL-8 Series uses. Time delay is analog set on other encapsulated series.

17.5mm WIDE, DIN-RAIL

Choose from single (TE-6 Series) or multi-function (TE-881 Series). These compact relays mount on 35 mm DIN-rail to conserve space and reduce installation time.

30 AMP ENCAPSULATED

High Amp TH4 Series effectively and economically control heavy loads without a separerate contactor. The relays combine time-based control with high amperage switching capacity in compact 2” x 3” encapsulated enclosures.

1/16 DIN MOUNTING

Relays with 1/16 DIN style enclosures include an adapter for panel or surface mounting. TAD Series use push-button thumbwheels to set the time delay shown on a LED display. TAA Series use a large dial to set the time delay.

Frequently Asked Questions About Time Delay Relays

WHAT TERMINALS WILL WORK WITH MACROMATIC SOCKETS?

Our wide array of sockets can accept stripped wire, ferrules, ring and fork terminals. Read more details about the size and types of terminal a specific socket can accept.

If you are an Authorized Macromatic Distributor, click on “Registration Form” at the upper left corner on the Checkout page.

You can also LOG IN after selecting products. On the Checkout page you can register as a Returning Customer, create a New Customer account, or use Guest Checkout.

WHAT IS THE CURRENT OR POWER DRAW OF YOUR RELAYS?

Macromatic relays specify the power consumed by the device as “burden” in units of VA. Look for the burden specification in the catalog page for the specific device you have. The unit of VA(volt-amps) is essentially the same as Watts(power), current draw can be calculated in Amps by taking the VA specification and dividing by the voltage control voltage you are using to power the device.

CAN I SET THE ON TIME AND OFF TIME SEPARATELY ON A CYCLE TIMER?

If you need to set the ON and OFF time independently on a cycle timer then you need to select a product with either Repeat Cycle ON or repeat cycle OFF function. Although the operation is similar, Flasher ON and Flasher OFF function do not allow for independent setting of the ON and OFF times.

NEED A TIME DELAY RELAY TO POWER A COOLING FAN. WHEN THE EQUIPMENT TURNS OFF, I WANT TO RUN THE FAN FOR 1-2 MINS TO COOL IT DOWN.

This is an OFF Delay function. This function is available in several of our time delay relay product lines. Select the time delay relay series that works best for your application.

WHAT IS THE MINIMUM DURATION OF A TRIGGER PULSE TO A TIME DELAY RELAY?

Product specifications for all Macromatic time delay relays state a minimum of 50 ms in length for the application of a trigger.

HOW CAN I CROSS ANOTHER MANUFACTURERS PART NUMBER TO MACROMATIC?

Macromatic maintains an extensive cross reference database. Follow the link here.

HOW DO I SELECT THE RIGHT TIME DELAY FUNCTION. THERE ARE SO MANY?

We provide a detailed description and graphical representation of all our time delay relay function to help with selection, see link.

HOW DO I GET A TIME DELAY RELAY FOR 208/220VAC CONTROL VOLTAGES?

Macromatic time delay relays rated for 240VAC have an operating range of 204-264VAC for control voltage and are suited for 208/220/230/240/250V applications.

I WANT TO TURN ON AN AIR SOLENOID AND HAVE IT STAY ON FOR 10 SECONDS WHEN A PHOTO EYE IS TRIPPED. AFTER IT TIMES OUT IT NEEDS TO BE RESET. I PICKED TE-8812U. I AM NOT SURE WHICH FUNCTION WOULD WORK BEST. I ALSO NEED HELP UNDERSTANDING HOW TRIGGER S WORKS.

The function you are describe is the Retriggerable One Shot, setting E. The timing will start when there is a connection between A1 and S. This can be accomplished with a momentary or sustained switch placed between the two terminals.

Macromatic’s Time Delay Relay Function Guide

Important questions to ask. Understanding the differences between all the functions available in time delay relays can sometimes be a daunting task. When designing circuits using time delay relays, several questions must be asked. WHAT IS THE DIFFERENCE BETWEEN A CONTROL RELAY & A TIME DELAY RELAY? Time delay relays

Time Delay Relays with Fixed Time Delay

Issue: I would like to get a time delay relay with a fixed time delay vs. adjustable to both make it easy to set up & to avoid anyone from later changing the setting. What options do I have with either your plug-in or encapsulated products? Solution/Resolution: Macromatic will build

Remote Adjustable Time Delay

Issue: How can I set the time delay remotely, either adjustable or fixed? Solution/Resolution: There may be an application requiring the setting of the time delay “remotely” or at some distance from the time delay relay itself. For example, the requirement may call for an adjustment outside the control panel
