MACROMATIC TD-70822 Time Delay Relay, 120V AC/DC, 10A

Macromatic TD-70822 time delay relay is suitable for selecting time delay between 50 ms & 999 hours. This relay unit can be programmed by pushbutton thumbwheels to digitally set the time delay & function required. The digital setting of time delay offers more accuracy than other relay units having an analogue potentiometer.

Features:

• Macromatic TD-70822 time delay relay uses an 8-pin octal socket for proper wiring.
• It offers a Flasher (OFF 1st) function for the time delay of the circuit.
• This unit has one pushbutton thumbwheel for choosing between the 7 time ranges.
• It is equipped with an LED to indicate the unit's timing mode & the time-out condition.
• This unit has an input rating of 120V AC / DC and an output rating of 10A DPDT.
• It can operate at temperatures ranging from -28 to 65 degrees C (-18 to 149 degrees F).

Compatible Accessories:

• Solid State Switches: These switches are used to control the load current flowing into this relay unit.

Standards and Approvals:

• UL
• CE
• CSA

Frequently Asked Questions:

Q. How does the Flasher function work in this Macromatic TD-70822 time delay relay?

A. The time delay starts in the Flasher (OFF 1st) function when the voltage is applied and the relay is de-energised (Off condition). This unit energises after the first time delay and remains energised for another time delay interval. This cycle repeats till the input voltage is removed.

Q. How to install this Macromatic TD-70822 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 Macromatic TD-70822 time delay relay into the socket while properly orienting the key on the centre post.
