TD-78122 Macromatic Relays, TD Series

• DIP‑Switches for Accurate Digital Set of Time Delay
• 100ms ‑ 1,023 Hours Programmable Time Delay
• Uses Industry‑Standard 8 or 11 Pin Octal Sockets

The TD Series time delay relays offer an easy and accurate method to select any time delay between 100ms and 1,023 hours. Programming is accomplished using 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 and adding their corresponding values (see examples below). This method provides a greater setting accuracy than is found on other units with an analog potentiometer. An LED indicates relay status.
