The Macromatic TR-6312U time delay relay is a direct replacement of the TR-63122. Both feature the Repeat Cycle OFF function, meaning the OFF time is first, followed by the ON time (during which the output is energized), and then the cycle repeats. There are two main differences between these two models. One is that the older TR-63122 relay has an input voltage of 120V AC/DC, while the TR-6312U has a universal voltage range of 24-240V AC and 12-125V DC, covering a wider range of applications. The other difference is the timing ranges. The TR-63122 had 16 timing ranges from 0.6 seconds to 24 hours. The TR-6312U relay also has 16 timing ranges, but goes from 0.05 seconds to 100 hours.
