| Datasheet | Download Datasheet |
The Macromatic THR-12268-37 is a time delay relay with 1C SPDT output and rated 10 A at 240 V AC, 7 A at 28 V DC, driven by a 24V AC/DC input.
It is adjustable from 10 to 1,000 min and set by an onboard knob.
It is a Single Shot Falling Edge timer.
Upon application of control voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output remains de-energized. Upon removal of the trigger, the output is energized and the time delay (t) begins. At the end of the time delay (t), the output is de-energized unless the trigger is removed and re-applied prior to time out (before time delay (t) elapses). Continuous cycling of the trigger at a rate faster than the time delay (t) will cause the output to remain energized indefinitely.
It is started by a control switch.
It has Surface Mounting and 0.250" (6.3mm) quick-connect terminals.
