SSAC TDM120AL Digi-Set Time Delay Relay 10A 120V

The SSAC TDM120AL is a precision delay-on-make time delay relay, engineered to deliver accurate timing control in industrial applications. This device integrates advanced digital circuitry with isolated, double-pole double-throw (DPDT) relay contacts, all housed within a standard 8-pin plug-in package.

Key Features

• Adjustable Time Delay: Offers a selectable delay range from 1 to 1,023 seconds, adjustable in 1-second increments via DIP switches, allowing for precise timing customization.
• High Accuracy: Ensures repeat accuracy of ±0.1% and setting accuracy of ±2%, providing reliable performance in critical applications.
• Robust Output Contacts: Equipped with isolated 10A DPDT contacts, capable of handling resistive loads up to 10A at 120/240VAC and 28VDC, as well as motor loads up to 1/3 horsepower at 120/240VAC.
• LED Status Indicator: Features an LED that illuminates during the timing cycle, offering clear visual indication of the relay’s status.
• Compact and Versatile Design: Designed for easy integration into control panels, with an octal 8-pin plug-in termination for straightforward installation and replacement.

Operational Overview

Upon application of input voltage, the TDM120AL initiates the preset time delay. During this period, the output remains de-energized. Once the delay elapses, the output relay energizes and stays energized until the input voltage is removed. Resetting the device is achieved by removing the input voltage, which resets both the time delay and the output.
