| Datasheet | Download Datasheet |
The Macromatic RT26B-09 is a reset timer with SPNO output and rated 10 A at 240 V AC, 7 A at 28 V DC, driven by a 120V AC input.
It times out unless a reset signal keeps restarting it, with the delay adjustable from 1.2 to 120 seconds.
When the delay runs out, the output energizes and its normally closed contact opens, so whatever that contact was holding up drops out.
It keeps no memory through a power loss: when the supply comes back, the delay starts again from zero.
It has Surface Mounting and Quick Connect - 0.250" (6.35mm) terminals.
