| Datasheet | Download Datasheet |
The Macromatic TR-55121-13 is a time delay relay with 2C DPDT output and rated 10 A at 240 V AC, 10 A at 30 V DC, driven by a 240V AC input.
It is adjustable from 4.5 to 450 s and set by an onboard knob.
It is a Repeat Cycle (On 1st) timer.
Upon application of control voltage, the output is energized and the time delay (t1) begins. At the end of the time delay (t1), the output is de-energized and remains in that condition for the time delay (t2). At the end of this time delay, the output is energized and the sequence repeats until input voltage is removed.
It has Socketable mounting and Plug In terminals.
