MACROMATIC TD-84121-40 Time Delay Relay, 240VAC, 10A

Macromatic TD-84121-40 time delay relay is ideal for selecting a time delay between 0.1 to 102.3 seconds. This TD-8 Series relay unit can be programmed by moving the increment switches of a 10-position DIP switch and adding their corresponding values. It is equipped with an LED that indicates the status of the relay.

Features:

• Macromatic TD-84121-40 time delay relay offers an On / Off delay function with separate On & Off time ranges in energising the circuit.
• It is equipped with an LED that lights to a green colour for indicating the unit's power status and lights to red colour to show the energised relay status.
• This unit has DPDT output contacts rating of 10A at 240VAC / 30VDC, 1/2hp at 120 / 240VAC (N.O.), 1/3hp at 120 / 240VAC (N.C.).
• It can operate in temperatures ranging from -28 to 65 degrees C (-18 to 149 degrees F).
• This pilot-duty rated relay requires 11-pin octal sockets for proper wiring.
• It has a mechanical operating life of 10000000 operations and full load life of 100000 operations.

Standards and Approvals:

• UL
• CE
• CSA

Frequently Asked Questions:

Q. How does the On / Off Delay function work in this Macromatic TD-84121-40 time delay relay?

A. After the input voltage is applied, a trigger can be applied to the relay unit which will start the time delay (t1). After this time delay (t1), the output becomes energised. The output contacts stay in energised state for the time delay (t2) after the trigger is removed. After the time delay (t2), the output becomes de-energised & the time delay relay becomes ready for another trigger. Removing the trigger during the time delay period (t1) de-energises the output and resets the time delay (t1). Reapplying the trigger during the time delay period (t2) causes the output to remain energised and resets the time delay (t2).

Q. How to install this Macromatic TD-84121-40 time delay relay?

A.

• Mount an appropriate socket inside a suitable enclosure & wire it according to the wiring diagram.
• Users should match the terminal numbers of the socket with the relay unit's wiring diagram.
• Plug the Macromatic TD-84121-40 time delay relay into the socket while properly orienting the key on the centre post.

Q. What to do in case this Macromatic TD-84121-40 time delay relay fails to operate properly?

A. If this relay unit does not operate properly, users should check all the connections while following the correct wiring diagrams on the product.
