| Datasheet | Download Datasheet |
The Macromatic RT16B-12 is a reset timer with SPNO output and rated 10 A at 240 V AC, 7 A at 28 V DC, driven by a 240V AC input.
It times out unless a reset signal keeps restarting it, with the delay adjustable from 3 to 300 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.
