| Datasheet | Download Datasheet |
The Macromatic THR-3856U 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 24-240V AC & 12-125V DC input.
It is adjustable from 0.1 s to 1,000 min and set by DIP switches and knob.
Its second delay adjusts from 0.1 s to 1,000 min.
It offers Repeat Cycle (Off 1st), Repeat Cycle (On 1st), Delayed Interval, Delayed Interval (Switch Trigger).
It is started by applying the supply or a control switch, depending on the function.
It has Surface Mounting and 0.250" (6.3mm) quick-connect terminals.
