• Available as either a multifunction version with 16 functions built-in or as individual function versions
• DIP-Switches for accurate digital set of time delay (multi- & single-function) & selection of function (for multi-function only)
• Programmable delay of 100ms - 1,023 hours (multi-function) or 100ms - 1,023 minutes (single-function)
• Uses industry-standard 8 & 11 pin octal sockets
• 10A DPDT output contacts
• LED indicates relay status

The TD-8 series of time delay relays offer an easy and accurate way to select any time delay between 100ms & 1,023 hours. Programming is accomplished through the use of 10-position DIP-switches. This method provides a greater setting accuracy than is found on other units with an analog potentiometer. An LED indicates relay status.

The TD-8 series comes in two versions: a multi-function product with 16 functions built-in or a single function product.

Multi-Function

The TD-881 Series offers the digital-set accuracy of DIP-switch setting as well as the flexible programmability of a multi-function & multi-time range relay. These products provide an easy & accurate method to select any of 16 time delay functions and any time range between 100ms and 1,023 hours. This product can literally replace hundreds of different catalog numbers, thereby reducing inventory requirements.

Programming Function & Time Delay

Programming is accomplished through the use of two 10-position DIP-switches (see drawings at right). Switches A-D of the left-mounted DIP-switch are used to select a function. Switches E-K of the same DIP-switch are used to select the time base. A convenient chart is on the side of the relay to clearly illustrate how to set both the function & time base.

The right-mounted 10-position DIP-switch is used to select the time delay within the time base selected with switches E-K from the first DIP-switch. Each position on the second DIP-switch is marked with a binary time increment. The required delay is selected by moving the switch of each increment to the ON position & adding their corresponding values (see right). Note that dual mode products can either have the same or different ON & OFF times.

Single-Function

The TD-8 Series time delay relays offer an easy & accurate method to select any time delay between 100ms & 1,023 minutes. Programming is accomplished through the use of a 10-position DIP-switch. Each position is marked with a binary time increment. The required delay is selected by moving the switch of each increment to the ON position & adding their corresponding values (see examples at right). This method provides a greater setting accuracy than is found on other units with an analog potentiometer. An LED indicates relay status.
