Through advanced circuit design and packaging technology, the 313B Series Plug-in Adjustable Time Delay Relay from the Automatic Timing and Controls division of Marsh Bellofram Corporation packs all of the performance of a conventional plug-in TDR in a space-saving housing.
The 313B Series Plug-in Adjustable Time Delay Relay further features a digital timing circuit which ensures high repeat accuracy and excellent noise immunity.
Miniature Housing: You can mount several ATC 313B Series Plug-in Adjustable Time Delay Relays in the same space as a single conventional TDR
Digital Accuracy: A custom C-MOS integrated circuit accurately measures the dial-adjustable delay by counting the output of an internal oscillator. Repeat accuracy remains high even with variations in voltage, temperature and reset time
Status Indicators: Two LEDs clearly indicate the operational status of 313B Series Plug-in Adjustable Time Delay Relays: one is energized when power is applied; the other is off during the delay period and on at time-out.
Industrial Quality: With a load relay capable of switching 7A resistive loads and a C-MOS design that protects components against noise and voltage transients, the 313B Series Plug-in Adjustable Time Delay Relay is built for industrial use.
